PROCESS FOR PRODUCING SEMICONDUCTOR DEVICE, SEMICONDUCTOR DEVICE, SEMICONDUCTOR PRODUCTION APPARATUS, AND STORAGE MEDIUM

摘要

This invention provides a process for producing a semiconductor device, comprising a step (a) of activating an organic silane gas containing a phenyl group and silicon and free from nitrogen other than unavoidable impurities to produce plasma, and, in such a state that the temperature of a substrate is set at 200°C or below, exposing the substrate to the plasma to form a thin film containing a phenyl group and silicon on the substrate, and a step (b) of applying energy to the substrate to eliminate water from the thin film to form a low-permittivity film. This production process can provide an organic material-containing silicon oxide-type low-permittivity film which, when subjected to etching treatment, ashing treatment or other plasma treatment, does not cause any significant damage caused by the elimination of the organic matter.
