ABSTRACT:
A method of manufacturing a semiconductor device, which comprises the steps of, selectively silylating a photosensitive resin film by exposing the photosensitive resin film according to an exposure pattern thereby to form a silylated portion having a glass transition temperature which is lower than that of the photosensitive resin film and at the same time exposing the photosensitive resin film to an intermediate temperature between the glass transition temperature of the silylated portion and the glass transition temperature of the photosensitive resin film thereby fluidizing the silylated portion so as to cover a portion of the photosensitive resin film neighboring the silylated portion with the fluidized silylated portion, and developing the photosensitive resin film by making use of the silylated portion and the portion of photosensitive resin film covered by the fluidized silylated portion as a mask.
