ABSTRACT:
A small glass electrode and process for preparation thereof, the small glass electrode having a bonded structure and comprising a reference electrode composed of silver/silver chloride, a glass substrate having a pad embedded therein, the pad being composed of gold or platinum and circuit-connected to the reference electrode, and a silicon substrate having a (100) plane selectively etched by the anisotropic etching technique and comprising a groove for injecting an electrolyte composed of an aqueous solution containing chlorine such as KCA, or HCA, at least one hole for holding the electrolyte and a glass film formed in a portion corresponding to the reference electrode. The structure of the small glass electrode may be produced by the disclosed process easily and at low cost. Additionally, the small glass electrode, in differing embodiments, may include a reference electrode and a temperature sensor.
