    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: There is provided a semiconductor device which is formed on a semiconductor substrate and allows effective use of the feature of the semiconductor substrate, and there is also provided a method of manufacturing the same. An N-channel MOS transistor including a P-type body layer (3a), and a P-type active layer (6) for body voltage application which is in contact with the P-type body layer (3a) are formed on an SOI substrate which is formed to align a crystal direction of a support substrate (1) with a crystal direction of an SOI layer (3). A path connecting the P-type body layer (3a) and the P-type active layer (6) for body voltage application is aligned parallel to the crystal direction of the SOI layer (3). Since hole mobility is higher in the crystal direction, parasitic resistance (Ra, Rb) can be reduced in the above path. This speeds up voltage transmission to the P-type body layer (3a) and improves voltage fixing capability in the P-type body layer (3a).

    摘要: A channel region (2), a source region (3) and a drain region (4) are formed on a polycrystalline semiconductor layer (1). The characteristic of a polycrystalline TFT (101) is dispersed by the amount of crystal grain boundaries (6) contained in the channel region (2). A drain current is reduced as the amount of the crystal grain boundaries (6) contained in the channel region (2) is increased. In order to utilize a code obtained by encoding the electric characteristic of the TFT (101) for identification of a semiconductor chip, a system or the like, the TFT (101) is mounted on the semiconductor chip, the system or the like along with an encoder circuit. Thus, a barrier against illegal use of a user terminal is improved at a low cost.
