Silicon Carbide (SiC) wafers are semiconductor substrates made from a compound of silicon and carbon. SiC is a wide bandgap semiconductor, unlike wafer manufacturing with simple silicon, which means it can operate under extreme conditions, including high temperatures, high voltages, and high frequencies. This makes SiC wafers ideal for demanding electronic applications.
Structure and Properties of SiC
SiC is a compound semiconductor with a wider bandgap than silicon, which gives the material several advantages, such as:
High Breakdown Voltage: SiC can tolerate much higher electric fields before breaking down, making it perfect for high-voltage applications.
High Temperature Tolerance: Devices made from SiC can operate at temperatures exceeding 300°C.
Fast Switching Capabilities: SiC supports higher frequency operation, improving power electronics efficiency.
Uses of SiC Wafers
Due to their unique electrical and thermal properties, SiC wafers are used in a variety of high-performance applications, including:
Power Electronics:SiC-based MOSFETs, Schottky diodes, and IGBTs offer much higher efficiency than their silicon counterparts.
RF and Microwave Devices: SiC can operate at high frequencies and withstand high power, so it's used in RF amplifiers and microwave devices.
Aerospace and Defense: SiC’s durability under high temperature and radiation conditions makes it valuable in aerospace electronics, military systems, and satellite components where traditional materials might fail.
High-Temperature Sensors: SiC is also used to fabricate sensors that operate in harsh environments, such as combustion engines, jet turbines, or deep-well drilling systems.
