摘要: The present invention discloses an integrated ethanol gas sensor and fabrication thereof. The present invention utilities micro electro mechanical system (MEMS) technology and has a main sensing part in the form of a cantilever-bridge structure made of SiC thin film material arranged over a silicon substrate. The present invention integrates an SiC heater of comb or finger electrode shape and an SnO.sub.2 thin film gas sensing element applied over distinct portions on the same Si substrate together with Al2O3 and SnO2 thin films via a VLSI technology.
