Title:
METHOD FOR FORMING ORGANIC CONDUCTIVE THIN FILM, AND SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2005086144
Kind Code:
A
Abstract:

To provide a method for forming an organic conductive thin film capable of preventing formation of a step at the boundary of plural parts without causing deterioration in the organic conductive thin film, with a simple process.

A pentacen thin film 4 is formed on a silicon substrate 1 where electrodes 3A, 3B are formed, and a photomask 5 is placed on it. A width W of a chrome pattern 51 is the same as the clearance between the electrodes 3A, 3B. The chrome pattern 51 is arranged on a part 43 between the electrodes 3A, 3B of the thin film 4. An oxygen current is brought into contact with the thin film 4, and the thin film 4 is irradiated with ultraviolet rays 6 through the photomask 5. Thus, the part which is irradiated with ultraviolet rays becomes lower in the electric conductivity of the thin film 4 than that of the part 43 which is not irradiated with ultraviolet rays.
