Abstract

A temperature sensor, comprising: a diode structure including, a) a silicon substrate, b) a first region of a metal silicide in the silicon substrate, c) a second region of a metal-oxide semiconductor material on the first region, d) a third region of a metal over the second region; and, means for using the diode structure as a temperature sensitive device to measure an ambient temperature. The metal-oxide semiconductor material is preferably selected to have a bandgap of not less than about 3.0 eV.
