Title: Temperature measuring device and manufacture thereof
Inventor: FUJINO TAKESHI
IPC: G01K7/18
Filed: 1991-09-11
Abstract: PURPOSE:To make it possible to measure temperature even if the temperature of a test specimen is rapidly changed by using a thin film for the substrate of a metallic-wire forming part for measuring resistance change. CONSTITUTION:Silicon nitride or silicon carbide is used for a thin film part 4 which is formed in a silicon substrate 1. The thickness is made to be about 2mum. The thin film part 4 is used as a substrate, and a metallic wiring 2 is formed. Electrode terminals 3 which are connected to the wiring 2 are led out of the thin film part 4 and formed. Since the substrate of the forming part of the metallic wire 2 is made to be the thin film having the thickness of 2mum, the heat capacity of the thin film part 4, which is the substrate, is small, and the device can react with the rapid temperature change of the test specimen.
