Nexperia China Fully Upgrades to 12-Inch Wafer Platform, Ends Reliance on European Supply

September 30, 2025 — A Dutch administrative order placed Nexperia China (under Wingtech Technology) in a difficult position, cutting off its overseas wafer supply. After a prolonged supply disruption, the company has now achieved a breakthrough by fully upgrading to a 12-inch wafer process platform, simultaneously advancing new product validation and mass production ramp-up, thereby completely eliminating its reliance on European front-end wafer supply.

Background: A Fragmented Global Supply Chain

Previously, Nexperia’s production chain operated on a cross-border model: European wafer fabs handled front-end manufacturing, while facilities in China, Malaysia, and the Philippines managed packaging and testing. Leveraging its extensive automotive-grade product portfolio and its strategy of being "rooted in China, serving the world," Nexperia China’s Dongguan factory accounted for approximately 70% of the company’s global packaging and testing capacity.

However, due to restrictions on control over Nexperia’s overseas entities, the supply of certain overseas wafer and packaging capacities became severely constrained.

Strategic Response and Timeline

Following the disruption of overseas wafer supply channels, Nexperia China launched a concentrated effort in Q4 2025 to develop alternative solutions for transistor wafers. By the end of Q1 2026, the company had reached a partnership with a strategic partner in China, successfully completing the introduction of a 12-inch wafer process platform and simultaneously advancing new product validation and mass production.

Key Upgrades and Benefits

Through this collaboration, Nexperia China has fully upgraded products originally manufactured on 6-inch and 8-inch wafers in Europe to the 12-inch wafer process platform, achieving comprehensive improvements in manufacturing processes, product performance, and iteration speed.

• Cost Efficiency Optimization: The effective area of a 12-inch wafer is 2.25 times that of an 8-inch wafer, significantly increasing chip output per wafer. The economies of scale effectively reduce manufacturing costs, offering customers more competitive pricing.
• Improved Performance Consistency: Equipped with advanced fully automated production equipment, the platform delivers enhanced critical dimension control precision and narrower dispersion of electrical parameters, fully meeting automotive-grade requirements.

Product Portfolio and Quality Certification

Based on the 12-inch wafer process platform, Nexperia China’s power devices, logic devices, and bipolar discrete components have obtained automotive-grade quality system certifications, making them suitable for the stringent reliability, lifespan, and environmental tolerance standards of OEMs and Tier 1 suppliers.

Supply Chain Adjustments and Delivery Impact

Due to the supply chain restructuring, delivery schedules for MOSFETs, logic, and analog IC products experienced temporary pressure, which was reflected in the product revenue structure for the first half of the year. As supply chain optimization continues, the continuity of supply for these two product categories is gradually improving. Supply of transistor products is expected to return to normal levels by the second half of 2026.

Transistors and Protection Devices

The company has successfully completed the R&D and mass production of certain 12-inch wafer bipolar diodes and transistors, becoming the first company globally to master this core technology and achieve mass production. In the first half of the year, the company initiated a comprehensive upgrade of mainstream products originally manufactured on 6-inch and 8-inch wafers. Dozens of core platforms have either completed new product development or are in the R&D phase, covering a full range of small-signal diodes, transistors, protection devices, and various power devices.

MOSFET Power Devices

Leveraging its strategic partnership in China, the company has upgraded its MOS process platform to 12-inch wafers. Under the new platform, the cost and performance of MOS products have been significantly optimized. The newly launched T2x series MOSFETs, built on an advanced SGT platform, achieve world-leading performance. The company has also released a 40–100V automotive MOSFET product portfolio in industry-standard pin packages, designed for body control, infotainment, battery LED, and new energy applications.

Next-Generation IGBT Technology

In the area of next-generation IGBT technology, the company is advancing the development of its 1,200V FS8 series IGBTs. Positioned as the next-generation IGBT process platform, sample test results show performance superior to current seventh-generation IGBT products. The series is currently undergoing final reliability validation and is expected to become the world’s first new-generation IGBT to fully meet automotive-grade standards across all dimensions.

Logic and Analog ICs

The company is steadily building a self-controllable supply chain for logic and analog chips. Through its partnership, it has upgraded the process platform to 12-inch wafers, achieving significant improvements in product performance and cost. Currently, over 1,300 logic chip part numbers are in mass production on the 12-inch platform, covering consumer electronics applications.
