Abstract

This paper present characteristics of chromium oxide thin-film as piezoresistive sensors, which were deposited on Si substrates by DC reactive magnetron sputtering in an argon-Oxide atmosphere for high temperature applications. The chemical composition, physical and electrical properties and thermal stability ranges of the CrOx sensing elements have studied. CrOx thin films with a linear gauge factor(GF≒15), high electrical resistivity(ρ=340μΩ㎝) and TCR〈-55ppm/℃ have been obtained. These CrOx thin films may allow high temperature pressure sensor miniaturization to be achieved.
