Abstract

We report the deposition of 3C-SiC films on an Si(100) substrate from 1,3-disilabutane precursor molecule utilizing a conventional low-pressure chemical vapor deposition (CVD) system. The chemical, structural, and growth properties of the resulting films are investigated as functions of deposition temperature and flow rates. Based on X-ray photoelectron spectroscopy, the films deposited at temperatures as low as 650°C are indeed carbidic. X-ray diffraction analysis indicates the films to be amorphous up to 750°C, above which they become polycrystalline. The effect of process parameters on film uniformity is also reported. Highly uniform films are achieved at 800°C and lower, essentially independent of the flow rate. © 2004 The Electrochemical Society. All rights reserved.
