Abstract
There is proposed a method of forming an insulating film pattern, which enables an insulating pattern of high precision and low dielectric constant to be easily obtained by means of an alkali development with basic solution. This method comprises the steps of coating a photosensitive composition comprising a first silicone polymer having a specific monomer and a second silicone polymer having a specific monomer on a substrate thereby to form a film of photosensitive composition, selectively exposing the film of photosensitive composition, alkali-developing the exposed film to form a pattern, and heat-treating the pattern of the photosensitive composition film.
