Title:
THIN FILM OF CONDENSED POLYCYCLC AROMATIC COMPOUND, AND METHOD FOR PREPARING THIN FILM OF CONDENSED POLYCYCLC AROMATIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2005/087390
Kind Code:
A1
Abstract:
An organic semiconductor thin film exhibiting high mobility and a method for the preparation thereof, and a material for the preparation of said organic semiconductor thin film by a wet process and a method for preparation thereof are provided. Further, an organic semiconductor element excellent in electronic characteristics is provided. In an example, a mixture of high purity pentacene and 1,2,4-trichlorobenzene was heated to prepare a uniform solution, and a silicon substrate having a pattern of a gold electrode as a source/drain electrode formed thereon is heated to 100°C and the resultant pentacene solution was expanded on the surface of the substrate. 1,2,4-trichlorobenzene was evaporated, to thereby form a pentacene thin film, which resulted in the formation of a transistor.
