Nexperia China Says MOSFET, Logic IC Supply Chains Complete as Independent Operations Largely in Place

　　After last year’s control dispute between Wingtech and Nexperia’s Netherlands headquarters sent shockwaves through the industry, Nexperia China now says it has made significant progress in building independent operations. According to EE Times China, Wingtech Chairwoman Ruby Yang announced on May 29 that Nexperia China has largely completed the setup of its independent operating system.

　　Yang revealed that Nexperia China’s core management, R&D, and market teams are now fully based in China. The report notes that the company’s capacity and delivery capabilities have steadily recovered, while it continues to build a “China for China, China for Global” full-stack supply chain across wafer manufacturing, packaging and testing, and quality control.

　　The announcement comes as Wingtech faces mounting pressure. According to ESM China, the company said on April 29 that its auditor issued a “disclaimer of opinion” on its 2025 financial report, triggering a delisting risk warning under relevant rules.

　　Full-Stack Supply Chains Advance Across Key Product Lines

　　In terms of product layout, Nexperia China currently covers three core business lines: MOSFETs, logic ICs, and bipolar transistors, including protection devices. Yang said none of the three previously had a fully domestic, full-stack supply chain. However, according to the report, MOSFET and logic IC products have now established such supply chains.

　　The bipolar transistor line is being upgraded to a 12-inch platform and is expected to complete its full-stack domestic supply chain within 2026. Bipolar transistors entered small-batch mass production in March 2026, with capacity for protection devices such as ESD (Electrostatic Discharge) and TVS (Transient Voltage Suppressor) products expected to gradually come online in the second half of 2026, the report notes.

　　Under the plan, 19 products are expected to be ready for supply by next month, covering more than 80% of demand, the report adds. Despite the severe supply-chain fallout from last year’s Wingtech-Nexperia control dispute, the report indicates that Nexperia China has maintained large-scale delivery capabilities. Since mid-October 2025, it has shipped more than 11 billion chips to over 800 customers.

　　Wingtech Seeks Court Action in Nexperia Control Dispute

　　Meanwhile, the battle for control of Nexperia has escalated further. According to South China Morning Post, Wingtech said last week that it had filed a lawsuit in a court in China’s southern Guangdong province against Nexperia and three of its executives. The suit demands the restoration of full corporate control and 8 billion yuan, or US$1.18 billion, in compensation.

　　As Bloomberg notes, Wingtech asked the court to order the defendants to stop carrying out or supporting the disputed measures, including by withdrawing legal proceedings in the Netherlands and revoking a Dutch ministerial order issued last September under the Goods Availability Act. If the defendants fail to comply, Wingtech would seek the transfer of Nexperia and related subsidiaries to the company free of charge.
