Patent ID: 7777288

Claim:
An integrated circuit device comprising: a substrate; a multi-layer wiring structure provided on said substrate, said multi-layer wiring structure having a plurality of wiring layer structures, each wiring layer structure having wires and an insulation layer, and a single layer temperature monitor element which comprises a metal oxide, wherein said substrate and said multilayer wiring structure form a temperature sensor section and a logic circuit section, wherein in said temperature sensor section at least two wires of said wires are formed in an uppermost wiring layer structure of said plurality of wiring layer structure and in said logic circuit section at least one wire of said wires is formed in said uppermost wiring layer structure, and wherein said single layer temperature monitor element directly contacts said at least two wires formed in said uppermost wiring layer of said temperature sensor section, wherein said single layer temperature monitor element completely covers said at least two wires, wherein one of said at least two wires is connected to a ground potential wire and another of said at least two wires is connected to a power-source potential wire via a resistor, wherein an output terminal is connected between said single layer temperature monitor element and said resistor, and wherein a mechanism is provided for detecting a potential of said output terminal by applying a ground potential to said ground wire and a power-source potential to said power-source potential wire.
