Title:
MANUFACTURE OF SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
Japanese Patent JPH0541337
Kind Code:
A
Abstract:

PURPOSE: To make small the value of an ESR in a solid electrolytic capacitor.

CONSTITUTION: In a method of forming a semiconductor layer 3 of a solid electrolytic capacitor which is formed by laminating in order a dielectric oxide film layer 2, the layer 3 and a conductor layer 4, a polyaniline solution, which is obtained by dedoping a polyaniline polymertized at a low temperature by a chemical oxidation method and is soluble to an organic solvent, and a high- molecular solution having a sulfone group to work as a dopant are alternately made to soak in the upper part of the layer 2. Thereby, the insoluble polyaniline semiconductor layer 3 is formed.
