    摘要: Even if the insulated isolation structure which makes element isolation using partial and full isolation combined use technology is manufactured, the manufacturing method of a semiconductor device which can manufacture the semiconductor device with which characteristics good as a semiconductor element formed in the SOI layer where insulated isolation was made are obtained is obtained. Etching to an inner wall oxide film and an SOI layer is performed by using as a mask the resist and trench mask which were patterned, and the trench for full isolation which penetrates an SOI layer and reaches an embedded insulating layer is formed. Although a part of CVD oxide films with which the resist is not formed in the upper part are removed at this time, since a silicon nitride film is protected by the CVD oxide film, the thickness of a silicon nitride film is kept constant. Then, after removing the resist and depositing an isolation oxide film on the whole surface, an isolation oxide film is flattened in good thickness precision in the height specified by the thickness of a silicon nitride film by performing CMP treatment which used the silicon nitride film as the polishing stopper.

    摘要: A partial oxide film (31) with well regions formed therebeneath isolates transistor formation regions in an SOI layer (3) from each other. A p-type well region (11) is formed beneath part of the partial oxide film (31) which isolates NMOS transistors from each other, and an n-type well region (12) is formed beneath part of the partial oxide film (31) which isolates PMOS transistors from each other. The p-type well region (11) and the n-type well region (12) are formed in side-by-side relation beneath part of the partial oxide film (31) which provides isolation between the NMOS and PMOS transistors. A body region is in contact with the well region (11) adjacent thereto. An interconnect layer formed on an interlayer insulation film (4) is electrically connected to the body region through a body contact provided in the interlayer insulation film (4). A semiconductor device having an SOI structure reduces a floating-substrate effect.

    摘要: A contact connected to a word line is formed on a gate electrode of an access transistor of an SRAM cell. The contact passes through an element isolation insulating film to reach an SOI layer. A body region of a driver transistor and that of the access transistor are electrically connected with each other through the SOI layer located under the element isolation insulating film. Therefore, the access transistor is in a DTMOS structure having the gate electrode connected with the body region through the contact, which in turn is also electrically connected to the body region of the driver transistor. Thus, operations can be stabilized while suppressing increase of an area for forming the SRAM cell.
