Abstract:
1. A method of forming a semiconductor device, the method comprising: forming a multilayer structure including a first film on a substrate and including a second film on the first firm, the first film comprising an organic semiconductor; applying a gas to the multilayer structure, the gas comprising a dedoping compound, the second film being configured to be permeable to the gas after forming the multilayer structure; wherein the dedoping compound has a structure represented by formula (I); and sealing the multilayer structure after applying the gas to the multilayer structure; wherein R 1 -R 8 each independently represents a hydrogen atom or a C 1 -C 6 alkyl group which may be linear or branched and which may be optionally substituted with one or more hydroxyl groups and/or one or more halogen atoms and/or a C 1 -C 3 alkoxy group; one or more pairs of R groups which are not hydrogen may join to form a cyclic group according to the following pairings: R 1 and R 2 ; R R R R R R R
