摘要： An insulating layer is formed on a semiconductor substrate, and a first resist layer having a first resist opening portion is formed on the insulating layer. Then, the insulating layer is etched thought the opening portion to expose the substrate. After removing the first resist layer, a second resist layer having second resist opening portions are formed. One of the second resist opening portions is provided to expose the substrate, and a recess is formed in the substrate through the opening portion. Further, the insulating layer exposed from the other of the second resist opening portions is removed. Then, an electrode member for gate, source, and drain electrodes is deposited on the substrate. As a result, variations in intervals between the gate and drain electrodes and between the gate and source electrodes can be reduced.

摘要： An analog switching circuit comprises an insulated-gate field-effect transistor (Q20) having two n-type input-side and outpu-side semiconductor regions (201, 202) and a p-type semiconductor substrate region 203, for controlling conductiveness between an input terminal (IN) and an output terminal (OUT) based on a gate potential. A surge pulse detecting circuit (1020), responsive to an electric potential (Vi) of the input terminal (IN), produces a detection signal of a surge pulse equivalent to a forward bias of a PN junction formed between the semiconductor substrate region (203) and the input-side semiconductor region (201). A substrate potential setting circuit (1010) varies an electric potential of the semiconductor substrate region (203) in response to the electric potential (Vi) of the input terminal (IN) when aby detection signal is produced. Furthermore, a gate potential control circuit (1030) varies the gate potential of the insulated-gate field-effect transistor (Q20) in the same direction as the electric potential of the semiconductor substrate region (203) when the detection signal is produced.
