    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: A buried oxide film 4 is formed on a main surface of a silicon substrate 1. An SOI layer 5 is formed on buried oxide film 4. Channel stop regions 22a and 22b respectively connected to channel regions of an nMOS 2 and a pMOS 3 are formed in an element isolation region of SOI layer 5. nMOS 2 and pMOS 3 are formed in an element formation region of SOI layer. A concentration of a p type impurity or an n type impurity included in channel stop regions 22a and 22b is higher than a concentration of the p type impurity or the n type impurity included in the channel region of nMOS 2 or the channel region of pMOS 3. An FS gate 16 is formed on channel stop regions 22a and 22b with an FS gate oxide film 15 interposed therebetween. Therefore, a semiconductor device having an SOI structure which is capable of suppressing a parasitic bipolar operation by drawing out efficiently excessive carriers stored in the channel region of transistor can be obtained.
