The global automotive semiconductor industry maintains robust growth driven by rapid electric vehicle popularization and continuous intelligent driving technology advancement. Modern new energy vehicles deploy massive quantities of power control chips, automotive MCUs, radar MEMS sensors and onboard computing chips, all of which rely on high-performance wafer substrates as core foundational materials. Vehicle-grade chips have extremely strict long-term reliability standards for substrate performance, creating strong, sustained rising demand for high-quality thermal oxide wafers and SOI wafers across the automotive supply chain.
For automotive power chips and vehicle MEMS sensors deployed inside engine compartments, battery management systems and autonomous driving sensing modules, wafers need excellent dielectric insulation performance, solid radiation resistance, and highly stable thermal oxide layer structure to endure harsh operating conditions including drastic working temperature swings, frequent voltage fluctuation, mechanical vibration and long-term outdoor exposure. Mass-produced standard commercial wafers are engineered for consumer electronics scenarios, and cannot satisfy these rigorous automotive-grade durability requirements. For this reason, automotive chip design houses and component manufacturers are increasingly sourcing customizable wafer products from specialized, process-capable wafer suppliers to achieve qualified substrate performance.
