Abstract
A power device includes a semiconductor substrate having first and second current carrying terminals on respective first and second opposing surfaces thereof. A silicided polysilicon temperature sensor and silicided polysilicon gate electrode are provided on the first surface. A source region of first conductivity type and a shielding region of second conductivity type are provided in the semiconductor substrate. The shielding region forms a P-N rectifying junction with the source region, and extends between the silicided polysilicon temperature sensor and the second current carrying terminal. A field oxide insulating region is provided, which extends between the shielding region and the silicided polysilicon temperature sensor.
