发明名称 Integrated circuit device
摘要 In a temperature sensor section of a semiconductor integrated circuit device, first vias of tungsten are formed at the topmost layer of a multi-layer wiring layer and pads of titanium are provided on regions of the multi-layer wiring layer which covers the vias. An insulating layer is provided in such a way as to cover the multi-layer wiring layer and the pads, second vias are so formed as to reach the pads. Vanadium oxide is buried in the second vias by reactive sputtering, and a temperature monitor part of vanadium oxide is provided in such a way as to connect the second vias each other. Accordingly, the temperature monitor part is connected between the two wires.
