METHOD FOR FORMING SEMICONDUCTOR THIN FILM AND METHOD FOR MANUFACTURING THIN FILM SEMICONDUCTOR DEVICE

摘要

Provided is a method for forming a semiconductor thin film, by which the semiconductor thin film wherein mobility deterioration due to heat and characteristic deterioration due to the mobility deterioration can be suppressed and heat resistance is improved can be obtained by more simple steps. A solution wherein a plurality of kinds of organic materials, including an organic semiconductor material, are mixed is applied or printed on a substrate and a thin film is formed. Then, a plurality of kinds of the organic materials are phase-separated in a step of drying the thin film. Thus, a semiconductor thin film (1) having a lamination structure wherein an intermediate layer (b) composed of an organic insulating material is sandwiched between two semiconductor layers (a, a') is obtained.
