Title: Electrode structure of sensor
Inventor: NISHIDA TOSHIO
IPC: G01N27/12
Filed: 1987-10-16
Abstract: PURPOSE:To enable the prevention of deterioration of a metal electrode, an oxide sensor layer and an insulating layer, by laminating a second metal electrode layer on a first metal electrode layer. CONSTITUTION:A composite is formed by laminating an Al electrode layer 3 and an Mo electrode layer 10. Moreover, a resist pattern 5 is formed and developed for processing the composite electrode. Next, etching is conducted by using an etching liquid. An unnecessary part is removed by this etching. Then, the pattern 5 is exfoliated by using a resist exfoliation liquid. Since the electrode layer 3 is covered with the electrode layer 10, a difference in equilibrium electrode potential between the electrode layer 3 and an oxide sensor layer 2 in a resist developing liquid is small. Therefore an electrochemical reaction is suppressed, and not only the deterioration of the electrode layer 3, but also deteriorations such as corrosion, exfoliation, cloudiness and degeneration of the ground sensor layer 2 occurring in a hatched part indicated by a mark A, can be prevented.
