STMicroelectronics Automotive Chip Shortage Worsens, AI Occupies 8-inch Wafer Capacity, Industrial ST MCU Spot Stock Ready for Fast Delivery on LXBCHIP
Introduction
The global automotive industry, still recovering from the chip shortages of the past few years, is facing a new challenge. STMicroelectronics (ST), a key player in the automotive semiconductor market, is warning that the shortage of automotive-grade chips is set to worsen in the second half of 2026. The root cause? A massive shift in 8-inch wafer production capacity towards AI-related applications.
The Capacity Crunch: AI vs. Automotive
STMicroelectronics, like many other chipmakers, is reallocating its manufacturing resources to meet the explosive demand for AI chips. This has come at a cost to traditional markets:
- 8-inch Wafer Impact: Approximately 30% of ST’s 8-inch wafer capacity, previously dedicated to producing automotive MCUs and power MOSFETs, is now being used for AI power management ICs and other high-margin AI components.
- Lead Time Extension: As a direct result, the lead time for ST’s automotive 32-bit MCUs (e.g., STM32F7, STM32H7 series) has been extended to 20-26 weeks. Some high-demand models are quoted at over 30 weeks.
- Power MOSFETs Under Pressure: STP-series power MOSFETs, critical for electric vehicle (EV) powertrains and charging infrastructure, are also facing supply constraints with lead times stretching beyond 18 weeks.
The Industrial Market Ripple Effect
The capacity shift isn’t just affecting the automotive sector. Industrial customers are also feeling the pinch:
- STM32F4/F103 Series: These workhorse industrial MCUs are now facing spot shortages in the open market, with distributors quoting prices 20-30% above the official list price.
- Global Tightness: Overseas distributors, anticipating further shortages, are hoarding stock, making it even harder for end-users to secure the components they need.
