ABSTRACT:
A semiconductor resistor element comprising a semiconductor film which has a desired shape and electrode wirings at both ends thereof, and a control electrode provided between the two ends of the semiconductor film via an insulating film. The control electrode is served with a control voltage which controls the resistance of the semiconductor film. Namely, the control electrode is served with a control voltage that changes with the change in temperature to offset the change in resistance of the semi-conductor film caused by the change in temperature.
