Process for producing a field effect transistor, a semiconductor device for producing ink, in field effect transistors, and organic heterocyclic compounds

摘要

The present invention provides a field-effect transistor characterized by using a semiconductor material compound represented by the following formula (1). (Equation (1), X ² and X ¹ is a C1-C36 aliphatic hydrocarbon group unsubstituted or halogeno-substituted independently each ^{R 2} and .R ¹ represents a sulfur atom, a selenium atom or a tellurium atom independently . represent)
