Silicon has been the leading semiconductor in Micro Electromechanical Systems (MEMS), where its applications can be found in numerous ubiquitous devices, including smart phone and personal computers. Nevertheless, when it comes to high temperature, high corrosion, and long term stability (e.g. implanted electronics), Si cannot withstand such critical conditions. Owing to its wide energy band gap, excellent optical and mechanical properties, silicon carbide has emerged as a promising alternative of Si for MEMS devices operated in harsh environments. In this talk, I will present our recent studies on the epitaxial growth of high quality single crystal cubic silicon carbide (3C-SiC) on a silicon wafer and its micro/nanomachining technologies at the Queensland Micro & Nanotechnology Centre, Griffith University. The physical properties of the as-deposited films such as piezoresistive effect for strain sensing, thermal resistive effect, and residual stress for sensing applications will also be discussed [1-5]. Finally, I will enclose my talk with a brief overview of SiC micro/nano devices such as strain sensors, temperature sensors, and electrochemical sensors, as well as its potential for the next generation of MEMS devices for harsh environments, energy harvesting and bio applications.
