Due to its outstanding electrical, chemical and mechanical properties, silicon carbide (SiC) is a leading material for MEMS in harsh environment appliions. Silicon carbide-on-oxide wafers are attractive substrates for SiC surface micromachined devices since the buried oxide layer provides both electrical isolation and serves as a sacial layer. Wafer bonding is commonly used to

SPTS and QMF grow 3C-SiC epi on 300mm silicon The Queensland Micro and Nanotechnology Facility (QMF) of Griffith University in Brisbane, Australia and its industry partner, plasma etch, deposition and thermal processing equipment maker SPTS Technologies Ltd of Newport, Wales, UK, have announced the epitaxial growth of 3C silicon carbide (SiC) films on 300mm silicon wafers.
8/7/2014· 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.
