Organic transistor element, and method of manufacturing the same by concurrently doping an organic semiconductor layer and wet etching an electrode provided on the organic semiconductor layer

摘要

In a method for manufacturing an organic transistor element, an electrode is subjected to wet etching into a predetermined pattern on an organic semiconductor layer. In the process for performing wet etching on the electrode so as to obtain a predetermined pattern, an etching liquid containing a dopant of the organic semiconductor layer is used to perform wet etching on the electrode and, simultaneously, the organic semiconductor layer is doped with the dopant.
