METHOD FOR FABRICATING THICK FILM TYPE GAS SENSOR

摘要

PURPOSE: A method for fabricating a thick film type gas sensor is provided to fabricate the thick film type gas sensor through a simple process by evenly distributing sensor powders in suspension liquid and uniformly depositing sensor powders on a substrate. CONSTITUTION: A thick film type gas sensor is fabricated by forming a thick film including sensor material on a substrate. Sensor materials are distributed in suspension liquid. Suspension liquid is subject to a centrifugal separation process in such a manner that sensor material is deposited on a predetermined portion of the substrate, which is positioned in perpendicular to a centrifugal force direction, thereby forming a thick film. Then, a heat treatment process is carried out with respect to the thick film. Before the heat treatment process for the thick film is carried out, a cold isostatic press is carried out.
