    摘要: An I/O protection circuit includes a P-channel MOS transistor connected between an input terminal and a power supply line, and an N-channel MOS transistor connected between the input terminal and a ground line. Gate electrodes of both the transistors are floated. The transistors may be replaced with gate diodes. Further, gate electrodes may be formed from the same layer as a gate electrode provided for field shielding.

    摘要: According to a semiconductor device of the present invention, a field oxide film is formed so as to cover the main surface of an SOI layer and to reach the main surface of a buried oxide film. As a result, a pMOS active region of the SOI and an nMOS active region of the SOI can be electrically isolated completely. Therefore, latchup can be prevented completely. As a result, it is possible to provide a semiconductor device using an SOI substrate which can implement high integration by eliminating reduction of the breakdown voltage between source and drain, which was a problem of a conventional SOI field effect transistor, as well as by efficiently disposing a body contact region, which hampers high integration, and a method of manufacturing the same.

    摘要: In a semiconductor device having an SOI structure and a method of manufacturing the same, influence by a parasitic transistor can be prevented, and no disadvantage is caused in connection with a manufacturing process. In this semiconductor device, an upper side portion of a semiconductor layer is rounded. Thereby, concentration of an electric field at the upper side portion of the semiconductor layer can be prevented. As a result, lowering of a threshold voltage of a parasitic transistor can be prevented, so that the parasitic transistor does not adversely affect subthreshold characteristics of a regular transistor. Owing to provision of a concavity of a U-shaped section, generation of etching residue can be prevented when etching a gate electrode for patterning the same. Thereby, a disadvantage is not caused in connection with the manufacturing process.
