Solid state sensor

摘要

A solid state sensor that is ideally well suited for detecting the presence of ozone in an atmosphere under ambient conditions. A metal oxide semiconductor is placed upon a glass substrate by heating the substrate to about 1200 DEG F. and then depositing molten granules of the metal oxide upon the heated substrate whereby the granules become fused to the substrate and each other to form a rough textured coating. The oxide coating is machined to a desired thickness using any one of many suitable machining operations.
