Abstract:
1. A method of manufacturing a semiconductor device comprising the steps of: forming a gate electrode layer over a light-transmitting substrate; forming a gate insulating layer containing an inorganic material over the gate electrode layer and the substrate; forming an organic layer containing a photopolymerizable reactive group over the gate insulating layer; polymerizing selectively the organic layer by irradiating the organic layer with light from back side of the substrate, using the gate electrode layer as a mask; forming an organic polymer layer by removing a residue of the organic layer, which is other than polymerized; forming an organosilane film including a hydrolytic group over the gate insulating layer in a region other than a region in which the organic polymer layer is formed; forming a source electrode layer and a drain electrode layer by applying a composition containing a conductive material over the organic polymer layer; and forming a semiconductor layer over the gate electrode layer, the source electrode layer, and the drain electrode layer.
