ABSTRACT:
A method for forming a pattern of an organic semiconductor film comprises applying at least a bicyclo compound onto a base material, the bicyclo compound being converted to an organic semiconductor on the base material through retro-Diels-Alder reaction which removes a part of the bicyclo skeleton to allow extension of pi electron system.
