    摘要: A conductivity-modulation MOSFET employs a substrate (30) of an N type conductivity as its N base. A first source layer (34) of a heavily-doped N type conductivity is formed in a P base layer (32) formed in the N base (30). A source electrode (38) electrically conducts the P base (32) and the source (34). A first gate electrode (36) insulatively covers a channel region (CH1) defined by the N⁺ source layer (34) in the P base (32). A P drain layer (44) is formed on an opposite substrate surface. An N⁺ second source layer (46) is formed in a P type drain layer (44) by diffusion to define a second channel region (CH2). A second gate electrode (40) insulatively covers the second channel region (CH2), thus providing a voltage-controlled turn-off controlling transistor. A drain electrode (48) of the MOSFET conducts the P type drain (44) and second source (46). When the turn-off controlling transistor is rendered conductive to turn off the MOSFET a "shorted anode structure" is temporarily formed wherein the N type base (30) is short-circuited to the drain electrode (48), whereby case, the flow of carriers accumulated in the N type base (30) into the drain electrode is facilitated to accelerate dispersion of carriers upon turn-off of the transistor.

    摘要: A semiconductor device includes a semiconductor substrate, a pair of low breakdown voltage elements formed in the substrate so as to be adjacent to each other, and a high breakdown voltage element formed to be adjacent to one of the low breakdown voltage elements. The pair of low breakdown voltage elements are isolated from each other by a pn junction and the one of the low breakdown voltage elements and the high breakdown voltage element are isolated from each other by a dielectric material. The semiconductor substrate is a composite substrate formed by directly bonding a first substrate serving as an element region to a second substrate serving as a supporting member through an insulating film.

    摘要: Disclosed is a method of manufacturing a semiconductor device, comprising the step of forming a semiconductor wafer having a first impurity-doped layer and a second impurity-doped layer having a higher impurity concentration than that of the first impurity-doped layer, comprising the steps of bringing a first semiconductor substrate (11), having a third impurity-doped layer (12) which has a higher impurity concentration than that of the first impurity-doped layer and the same conductivity type as that of the second impurity-doped layer, and whose surface is mirror-polished, into contact with a second semiconductor substrate (13) having a fourth impurity doped layer, which has a higher impurity concentration than that of the first impurity-doped layer and the same conductiviey type as that of the second impurity-doped layer, and whose surface is mirror-polished, so that the mirror-polished surfaces thereof are in contact with each other, and in a clean atmosphere so that virtually no foreign substances are present therebetween, and annealing the first and second semiconductor substrates (11,13) whose mirror-polished surfaces are in contact with each other at a temperature of not less than 200°C so as to bond them together, thereby forming the second impurity-doped layer consisting of the third and fourth impurity-doped layers.
