摘要:
A polyimide thin film is formed on a substrate by imparting energy under vacuum, by means of heating, ultraviolet light or electron beam irradiation, or a combination thereof, to a polyimide having in the polymer main chain imide bonds and decomposable bonds such as carbon-carbon single bond differing from the imide bonds so as to break the decomposable bonds.
