Carbon-based materials such as graphite, carbon fibers, and carbon/carbon (C/C) composites are known for their high specific strength, high specific modulus, and excellent thermal properties, making them suitable for a wide range of high-temperature applications. These materials are widely utilized in aerospace, chemical engineering, and energy storage. However, their susceptibility to oxidation and corrosion in high-temperature environments, along with poor scratch resistance, restricts their further application.

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

The ultra-high synthesis temperature and the difficulty of achieving dense sintering of SiC ceramics have limited their development. The sintering process is crucial for SiC ceramics.

Today, Onsemi announced on its official website that it has reached an agreement with Qorvo to acquire the SiC JFET technology business and Qorvo's subsidiary.

Oxidation processes play a critical role in preventing such problems by creating a protective layer on the wafer, known as the oxide layer, which acts as a barrier between different chemicals.

The new energy vehicle industry is quickly advancing toward high-quality growth, becoming an eagerly awaited part of the global supply chain. The automotive power module acts as the "power center" of new energy vehicles, responsible for converting the battery's DC power into the AC needed to operate the motor. It also manages the motor's speed and torque, directly affecting the vehicle's performance and energy efficiency.
