Abstract

SiC thin films less than 1 μm thick are grown by thermal decomposition of CH3SiC13 in a hydrogen atmosphere in an open CVD system. The interface stress is shown to be depend on the growth conditions. The optimal conditions for the preparation of uniform SiC films have been determined. Thermal annealing of the films has also been studied, and the conditions that provide for relaxation of the interface stresses are determined.
