Semiconductors have a wide range of applications in the automotive industry. With the increasing level of automotive electronics, semiconductor discrete devices, as basic components, meet the needs of automotive intelligence, informatization, and networking. For example, the popularity of LED energy-saving lamps in automotive main lights, indicator lights, lighting fixtures, decorative lights, and other areas has provided broad development space for semiconductor discrete devices. In addition, electronic systems in modern cars require a large amount of memory, such as storing vehicle information, driver preferences, audio and video, which has also driven the widespread application of semiconductor memory.
