Abstract:
1. A temperature-sensing device for use in protecting a heat-generating power device from an over-temperature condition comprises: a semiconductor substrate having a first surface, a second surface opposite of the first surface and a diode structure; a cathode and an anode electrically coupled to the diode structure and disposed on the first surface of the semiconductor substrate, wherein the diode structure is temperature sensitive such that a change in temperature of the diode structure causes a predictable change in the voltage drop across the anode and the cathode while a constant forward bias current is applied; a dielectric layer formed on the second surface of the semiconductor substrate such that the second surface of the semiconductor substrate is electrically isolated; and a metallization layer formed on the dielectric layer such that the metallization layer is bound to the dielectric and is attachable to a conductive or semiconductive substrate.
