Abstract:
A semiconductor device comprising:a semiconductor substrate on which a semiconductor circuit is formed,wherein the semiconductor circuit is a field effect transistor; anda regulating resistor network, formed on the semiconductor substrate, for regulating a voltage or current supplied to the semiconductor circuit,wherein the regulating resistor network includes a plurality of resistors connected in parallel to each other, andwherein each said resistor is cuttable by being irradiated with light, andwherein a resistance value of the regulating resistor network is adjustable by cutting at least one of the resistors off, andwherein the regulating resistor network is connected to a gate terminal of the field effect transistor, andwherein a bias voltage applied to the gate terminal of the field effect transistor is regulable by adjusting the resistance value of the regulating resistor network.
