Cat-CVD as a new fabrication technology of semiconductor devices

Cat-CVD, often called hot-wire CVD, is a new method to obtain device quality thin films at low substrate temperatures. In the method, gas molecules are decomposed by catalytic cracking reactions on heated catalyzer placed near substrates, instead of plasma decomposition in the conventional plasma enhanced CVD (PECVD). This paper is to review this Cat-CVD from fundamental mechanisms to device application. The features of Cat-CVD are demonstrated with comparison of PECVD.
