2014/7/8· BASiC 3C is developing cost effective cubic Silicon Carbide (3C-SiC) wafers produced in Colorado for power device manufacturers. While SiC is becoming the material of choice over Silicon (Si) and Gallium Nitride (GaN) for middle to high-end power device development, the traditional “4H” SiC material continues to experience issues in defects, stress, wafer diameter scaling and costs.

The company’s technique is to deposit SiC with a “3C” crystal structure on a silicon wafer, in effect SiC-on-silicon. Transistors made from SiC and gallium nitride (GaN) are being proposed as alternatives to silicon in power appliions because they can switch much faster, increasing efficiency and allowing magnetics to be shrunk, and have inherently better voltage capabilities.
This project presents the fabriion of MEMS employing a cubic silicon carbide (3C- SiC) on silicon wafer using newly developed ProTEK PSB as biotechnology photosensitive protection mask. This new biotechnology can reduce the nuer of processes and simplify the process flow with minimal impact on overall undercut performance. The 680 pm thick wafer is back-etched, leaving the 3C-SiC thin
Silicon carbide presents a high breakdown field (2-4 MV/cm) and a high energy band gap (2.3–3.2 eV), largely higher than for silicon. Within this frame, the cubic polytype of SiC (3C-SiC) is the only one that can be grown on a host substrate with the huge opportunity to grow only the silicon carbide thickness required for the targeted appliion.
It was found that homogeneous 3C-SiC(100) films were heteroepitaxially grown on both surfaces of the suspended Si(100) wafer simultaneously. The structural and electrical properties of the obtained 3C-SiC films on both surfaces were investigated by means of SEM, XRD, Raman and J-V measurements.
