AMEYA360:Experts Weigh Impact of Intel-Arm Collaboration

　　Intel Foundry Services and Arm agreed last month to optimize Arm’s IP for Intel’s upcoming 18A process technology (1.8 nm). The collaboration will focus on mobile designs and will undertake design technology co-optimization (DTCO) and system technology co-optimization (STCO), which means that Arm’s IP will be optimized both for Intel’s forthcoming production node and for the company’s advanced packaging technologies.　　Intel Foundry Services and Arm will jointly fine-tune Arm’s IP using the DTCO methodology for Intel’s 18A manufacturing process to optimize performance, power and costs of upcoming designs. One of the key fruits of this collaboration will be development of “an Arm-based mobile SoC and silicon technology demonstration and reference platform for chip designs,” which is a rather broad definition of the work.　　Meanwhile, Intel and Arm confirm that the work has commenced.　　“The work will validate the performance, power and area utilization of Arm SoC designs on the Intel 18A process,” a spokesperson for Intel told EE Times.　　“We are building custom IP to ensure optimal power, performance and area for Arm-based SoC design,” a spokesperson for Arm explained to EE Times. “With this announcement, we enable one more option to our licensees to choose from when they target advanced nodes for Arm-based SoC design.”

AMEYA360:ASML Ban Affects China’s Advancement in Chips

　　As part of an agreement between the U.S. government, the Netherlands, and Japan, ASML, Nikon, and Tokyo Electron won’t be supplying their high-end photolithography equipment to Chinese companies.　　According to the Wall Street Journal, “the Netherlands will bar ASML Holding NV, a Dutch maker of photolithography machines, from selling to China at least some immersion lithography machines, the most advanced kind of gear in the company’s deep ultraviolet lithography line.”　　ASML manufactures all of the world’s extreme ultraviolet lithography machines, which are critical for producing cutting-edge semiconductors.　　China could easily circumvent the export bans for advanced semiconductors, as it has been doing for many years. Acquiring huge lithography machines is much more difficult, and making them from scratch is nearly impossible. Furthermore, only a few hundred of those machines are sold every year, making it much easier to control their destination.　　ASML bans chip making equipment to China　　It is unknown how much of that critical equipment has already been sold to China and what capacity Chinese companies already have to produce the most advanced semiconductors.　　While China is unlikely to have the technology to produce sub-10nm chips, it is already investing in new fabs. Currently, only Taiwan’s TSMC can produce 5nm technology. To do that, it requires the advanced lithography machines that ASML has.　　Lithography in the U.S.　　A lithography system is a projection system. Light is projected through a blueprint of the pattern to print (known as a ‘mask’ or ‘reticle’). This process will be repeated 100 times or more, laying patterns on top of patterns to make a complete microchip.　　This crucial technology was discovered in 1957 by Jay Lathrop and James Nall, of the U.S. Army’s Diamond Ordnance Fuse Laboratories in Maryland. They patented the photolithographic techniques used to deposit thin-film metal strips about 200 micrometers wide to connect discrete transistors on a ceramic substrate.　　In 1959 Lathrop joined Texas Instruments, and Nall went to Fairchild Semiconductor. In 1958, engineers at Fairchild built one of the first “step-and-repeat” cameras to easily copy and multiply transistors on a single wafer using photolithography.　　In the early 1980s, GCA Corp. was considered the worldwide leader in photolithography and celebrated as one of the “hottest high-technology companies.” They invented the wafer stepper (the step-and-repeat camera), a device similar to a slide projector or a photographic enlarger, enabling further reductions in chip size. It was the first technology to exceed the 1-micron limit.　　At the time, Japanese competitors Nikon and Canon were catching up quickly and making bold technological investments. While American lithography companies were holding back in capital expenditures until they had a deal with semiconductor manufacturers, the Japanese worked hand-in-hand with them to define roadmaps and coordinate the delivery of new equipment.　　“It was impossible to make semiconductors without lithography tools, but the only remaining U.S. producers were struggling to survive,” wrote Chris Miller in Chip War: The Fight for the World’s Most Critical Technology.　　In 1993, after receiving at least $60 million in funds from the government-backed Sematech consortium, GCA closed its factory in Massachusetts as it could not compete with ASML, Nikon, and Canon.　　ASML can’t meet demand　　While other lithography manufacturers can print 10nm patterns, ASML’s EUV (extreme ultraviolet) technology enables the scale of the smallest feature to be reduced below that limit. That’s why they hold 100 percent of the market for the most advanced lithography machines.ASML Ban Affects China&#8217;s Advancement in Chips　　Recently, ASML reported revenues of $23 billion and $6.05 billion in net income for FY2022. The Dutch company sold 317 new and 28 used lithography systems to their customers. They expect an increase of 25 percent in net sales for FY2023.　　“For 2023, ASML expects continued strong growth with a net sales increase of more than 25 percent and a slight improvement in gross margin, relative to 2022. We expect first-quarter net sales between €6.1 billion and €6.5 billion with a gross margin between 49 percent and 50 percent,” said ASML President and CEO Peter Wennink.　　The new restrictions on exporting equipment to China won’t hurt the company’s bottom line, as the demand from Taiwan, Europe, and the U.S. will continue to grow.　　China might retaliate　　Chip-making equipment is critical for China’s ambitions to lead in artificial intelligence and quantum computing technologies.　　While it would be possible for large Chinese companies to source state-of-the-art chips and build new systems abroad, not being able to design and manufacture advanced semiconductors in mainland China is a step back in their ambitions.　　The Chinese government has not issued any comment yet on the new restrictions, but it will likely react. One possibility is trade restrictions on Western businesses.

AMEYA360:How to Avoid Electronic Component Storage Woes You

　　One of the standards that separates a qualified distributor from some of its more risky peers is proper storage and handling of electronic components. It may sound simple, but that’s part of the criteria component makers use when authorizing a channel partner.　　Using proper electronic component storage is a vital part of quality control. Relying on incorrect practices could mean products fail sooner than expected or never perform as they should. People also must have a problem-solving mindset as they tackle storage issues associated with electronic components. That might mean investing in climate-controlled storage or even pursuing automated options.　　Here are some helpful tips to keep in mind to avoid pitfalls:　　Understand the risks of electronic component storage failures　　Making mistakes or simply being uninformed about how to store electronic components can have numerous negative ramifications. When people know more about what can happen, that knowledge can motivate them to take the proper precautions and adopt preventive measures.　　image of electronic component storage in warehouseExperts warn oxidation and diffusion are two of the biggest risks to electronic components. However, the good news is there are strategic ways to prevent both outcomes. Oxidation does not happen in ultra-dry environments. Thus, keeping electronics parts in dry storage cabinets is one solution. Those products do not allow the required cathode reaction to occur and prevent oxidation.　　Another possibility is to put the electronic parts in vacuum-packed moisture-barrier bags. This option is an oxidation preventative, provided people fill the bags with nitrogen. Recent research confirmed humans are oxidation sources due to an ozone reaction with the skin’s fats and oils. It’s impossible to stop oxidation completely, but the practical methods described here are good starting points for minimizing it.　　Diffusion occurs when atmospheric vapor spreads into hygroscopic materials. As vapor pressure rises, printed circuit boards and other delicate electronic components are at a greater risk of absorbing moisture. However, putting the parts into moisture-barrier bags inside dry storage cabinets reduces the threat.　　Knowing about the primary aspects of electronic component storage allows people to act accordingly, become more familiar with how to combat issues and steer clear of them.　　Partner with providers of climate-controlled storage　　People who work at companies providing climate-controlled storage will be well-versed in meeting the needs and expectations of individuals working in the electronics industry. Ambient warehouses often provide effective electronic component storage by protecting parts from water damage and tampering.　　Keeping electronic parts at a consistent temperature is essential to ensuring they remain usable. Plastics can change shape in response to temperature fluctuations. Metals also expand and contract as the temperature shifts. However, an additional difficulty affecting electronics is it’s not typically possible to spot the damage without proceeding with disassembly.　　Having the electronic components in an environment characterized by the wrong relative humidity is also problematic. When the humidity is too low, the parts become brittle. That change can make them less able to withstand regular use. Conversely, overly high humidity negatively affects the conductivity of an electronic component.　　Most reputable companies offering climate-controlled storage solutions use various strategies to meet their aims. They might maintain dedicated temperature zones for different products or use seals around doors to minimize changes when people enter and exit. Another best practice is to have Internet of Things temperature sensors. They can help facility workers verify that conditions are as expected. Moreover, having backup climate-control systems is essential to planning for emergencies.　　Consider how automation might help　　Many of the electronics industry’s most prominent players are increasingly pursuing automation to improve workflows. Such efforts go beyond electronic component storage, but they can also include it. People have frequently raised the issue of microelectronics manufacturing returning to the U.S. in greater prominence. That won’t happen easily or quickly, but automation could streamline efforts and reduce errors.　　Consider Digi-Key, a low-volume, high-mix distributor that recently opened a new facility in Minnesota. The 2.2 million-square-foot distribution center is almost entirely automated. More specifically, parts-picking is the only task done by hand there. The location contains more than 27 miles of automated conveyor belts. Additionally, the average component order travels more than 3,200 feet inside the building to reach various destinations.　　Putting electronics parts in climate-controlled storage is a trusted way to protect them. However, many manufacturers go further by deploying automation to limit the amount of human contact the electronics components have as they move through a factory. Even the most conscientious people occasionally make errors that could cause storage-related risks for delicate parts.　　Automation leaves most of the work to intelligent systems that don’t get distracted or tired as humans do. That’s why some manufacturers automate the handling of printed circuit boards and use storage automation solutions. If an automated system puts electronic parts in the right places, there’s a reduced likelihood of errors. Plus, a well-tuned automated system is often much more efficient than people.　　Electronic component storage problems can cut into products and lead to upset customers if company representatives don’t adequately address them. Whether that means using climate-controlled storage, pursuing automation or investigating another strategy, people must act promptly and proactively rather than risk ruining valuable parts.　　Many electronics components are already in high demand and short supply. Storing them properly can help people cope with supply chain problems by ensuring more of the parts companies have available perform as expected.

AMEYA360:Distributors Boost Testing as Counterfeit Risks Rise

　　The risk of procuring counterfeit components always increases when electronic devices are in tight supply. Between 2021 and 2022 – the height of the unprecedented semiconductor shortage – reports of suspect or nonconforming parts increased by 35 percent, according to the ERAI, which collects data on counterfeits.　　Notably, global semiconductor sales were flat during that period.　　The reality is counterfeit components are omnipresent in the electronics supply chain. One of the most common scams is re-marking (or “blacktopping”) common or even sub-par components as pricier, high-reliability devices. Although the parts are authentic, they could fail in high-stress environments. Analog ICs, programmable logic ICs and microprocessor ICs are the most frequent targets of counterfeiters.　　Testing for counterfeit parts has been standard operating procedure at Sourceability since its founding in 2015　　Jens Gamperl, Sourceability　　Demand for component testing has increased significantly during the chip shortage despite costs — as much as $2,000 —  and delays that are incurred during the process. Testing is often outsourced and can damage sample devices. But for a portion of the distribution market, test capabilities distinguish them as trusted sources of supply.　　Independent, non-franchised distributors source from the open market where component makers, OEMs, EMS providers and other organizations sell excess inventory. Components that can’t be traced back to a factory; arrive in opened or damaged packaging; or are heavily discounted could be counterfeit. Stringent quality control (QC) has become paramount for top-tier independents.　　However, testing has created a backlog of orders as shortages stretch on. Last year, independent distributor Fusion Worldwide acquired a test house based in Singapore. Another independent, Sourceability, has established test labs in each of its 4 global warehouses. From the company’s founding in 2015 testing has been standard operating procedure, according to Jens Gamperl, CEO and founder of Sourceability.　　“The tide is turning for independent distributors, which often get confused with brokers,” he noted. “They are clearly two different things.”　　Brokers are opportunistic organizations that buy low and sell high during supply disruptions and have been known to set up shop, take orders; and then disappear after payment. They are a common source of counterfeit parts. ERAI saw suspect capacitor reports spike over a 5-year period that included a severe shortage.　　Trust but verify　　Based on sources of components Sourceability has a 3-level verification process. One of the biggest challenges in the open market, Gamperl said, are parts that are authentic but have been re-marked as something else.　　“There are different sources of counterfeits,” Gamperl explained. “What what we see once in a while is that a manufacturer decides that product is not on their quality level, and they send it to a destruction facility, and on the way the shipment gets lost.”　　Even products that can be traced back to manufacturers (level 1) are verified by brand, part number, packaging, date code and dimensions.  “We have a large database of known parts, so it’s relatively easy to test a component’s dimensions,” Gamperl said.　　Sourceability maintains data on components, suppliers and customers it has dealt with at one time or another. Customers sometimes ask distributors to procure parts on their behalf. “If we haven’t bought one part from a supplier in, say, 10 years, there’s usually a good reason,” Gamperl said.　　Level 2 testing is done on components bought from authorized distributors, which source directly from component factories. Sourceability checks for open packs, resealed packaging, cut tape or 3rd party packaging. Acceptable quality level sample inspection is done based on the quantity received, using various microscopy options to validate conformance.　　The risk of procuring counterfeit components always increases when electronic devices are in short supply“Where we have no traceability, we always do a level 3 inspection,” Gamperl said. These devices are sourced from independent distributors, contract manufacturers/other excess channels and brokers. Markings on components are tested for permanence – a destructive solvent test (heated solvent) is used to detect epoxy-based blacktopping.　　Devices are also analyzed through x-ray florescence (XRF), are tested for solderability and undergo chemical decapsulation.　　“This usually means we take the packaging off and go down to the die and view the wiring through x-rays,” Gamperl said. By removing external packaging on a semiconductor and exposing the semiconductor wafer or die, microscopic inspection of brand marks, trade marks, and laser die etching can be used to determine authenticity. These tests damage samples, but some customers in the automotive or defense industries, for example, will not accept shipments without seeing test results beforehand.　　Equipment or facility investment has become a cost of doing business for many independents. Sourceability’s labs use:　　High Power Microscopy Capabilities Keyence VHX5000, VHX7000, Olympus DSX1000　　Keyence IM-7020 Instant Measuring Equipment　　Heated Chemical Testing (HTC)　　Creative Electron TruView? Prime X-Ray Inspection System　　Glenbrook Technologies JEWEL BOX 70T　　RoHS Testing with X-Ray Fluorescence (XRF) Equipment Olympus : Xpert Model　　RoHS Testing with X-Ray Fluorescence (XRF) Equipment Fischer Technology-XDAL-237 SDD　　NISENE Jet-Etch Pro Acid Decapsulation System　　RPS Prelude Dip and Look Solderability Test System　　RPS Cadence Steam Aging System　　Memmert JEDEC J-STD-033 and UF260 Universal Drying Ovens　　Sometimes, functionality testing is the only way to spot a counterfeit part. Counterfeits are getting more sophisticated, Gamperl notes, and resellers are always a step behind. But out of 50,000 recent shipments, Sourceability caught 120 counterfeits. “That’s small portion, even if counterfeiting has increased,” he added.

AMEYA360:A Refutation of “China’s Underground Market of Chips Draws Desperate Automakers” by Bloomberg 2

　　In China, cars are basically standardized products when they leave the factory. In order to meet the personalized and diversified needs of car owners, there is a huge "car aftermarket", namely 4S stores, maintenance stations, and modification plants, where automobile enthusiasts can modify or add some products into their vehicles. Products in the aftermarket do not have to pass the vehicle regulations. These parts will never change the core electronic components or interfere with the car safety, as they belongs to peripheral products. I did a survey and found that most so-called car chips speculated in Huaqiangbei belong to this category! They do not belong to the ABS, ESP, and other parts asserted by Bloomberg in the article!　　Introduction to Slkor in Chinese and English　　III.Inspection of electronic components　　I, SONG Shiqiang, as a stall economist in Huaqiangbei and the General Manager of Kinghelm and Slkor, explored some rules by using the basic theories of "Kondratieff waves" and "Fiboracci Arc" in Macroeconomics. With due consideration of the effect of the cyclical constraints of the electronic component industry, functions of the electronic component reservoir in sales order configuration, I found out some rules of electronic business in Huaqiangbei. Once I had drunk too much in Huaqiangbei, I spoke the knack out in bragging.         A businesswoman heard about my elucidation on the knack and was consequently enlightened. She followed the ways and means proposed in the elucidation in her speculation and made much profit worth several Bentley cars. She even sent a Bentley model to me to express her gratitude. Businesswomen in Huaqiangbei sighed with astonishment that in addition to writing jokes and advertisement, Mr. SONG from Kinghelm also knew a lot about stall business in Huaqiangbei, "How I wish to meet him  before my speculation rather than after that". One day, I was having tea with businesswomen in Huaqiangbei to do a pre-sale roadshow for my new book “Guide to Speculation in Huaqiangbei”. I accidentally saw a boss throwing a package of glittering items into the trash can behind a small counter. I picked the package up because I enjoy learning. I found it was a package of thin objects covered with a thin layer of blue film! Later, I asked experts of the industry and knew that they were wafer scraps with demerits sold to Huaqiangbei at lower prices from wafer fabs.           Afterthese wafer scraps are sealed and tested, they become electronic components sold in counters and stalls in Huaqiangbei. If you want to trace the brand, model, or even the production date, you can find a professional testing company for help. If you need a testing authority, the No. 5th Research Institute of the Ministry of Industry and Information Technology (CEPREI) in Guangzhou is recommended. In contrast, White Horse Laboratories is a more convenient choice. Additionally, 360IC also has a lab similar to this. By chance, I found ways and means to test electronic components. For problems arising out of the electronic components, causes of problems should be analyzed. If there are disputes, all responsibilities should be clearly defined, or some information should be traced and confirmed. Then the test and inspection of electronic components will play a role.　　For example, a testing company has advanced ultrasonic testing equipment capable of doing non-destructive tests widely applied in material test, failure analysis, Research and Development (R&D), Quality Assurance and Reliability (QA/REL) tests. Items can be inspected include electronic components, LEDs, metal substrates, cracks, delamination, cavities and other irregularities. The image contrast can be used to identify the internal impedance anomalies of materials, to determine the shape and size of defects, and to determine the positions of defects. I observed wafer scraps mentioned above with a 1000x magnifying instrument lent from a friend of mine. They were found memory chip made by TSMC with models and capacity specifications clearly visible! Of course, the conventional opening, sol, electrical performance testing, sealing material testing, and sealing process analysis are all available. After this comprehensive test, similar to four ways of diagnosis --looking, listening, inquiring and feeling the pulse practiced by a doctor trained in the traditional Chinese medicine and blood test practiced by a doctor trained in the western medicine, the DNA result reveal the parents of a child clearly!　　Test results of wafer scraps found in Huaqiangbei　　What I want to state here under my name SONG Shiqiang from Kinghelm and Slkor is that in procurement of expensive chips especially those for vehicle use from Huaqingbei, the test report from the professional lab is prerequisite for the issuance of a Purchase Order from a customer for both samples and small batches. A buyer with rich procurement experience in Huaqiangbei knows the origin of a chip, the level of processing of a chip and stage of modifying for a chip through visual inspection with his naked eyes. That is why I was shocked by the simplicity involved in buying chips for vehicle use described in the article by Bloomberg easier than blowing a whistle. Too much emphasis on the importance of customer relationship in the article revealed a blurred business image in Huaqiangbei that is far away from real business practice. The prerequisite for business in Huaqiangbei is the stock available and the same stock with authenticity!
