    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 heterojunction bipolar transistor includes an emitter layer (11) of a first conductivity type, a base layer (12) of a second conductivity type adjacent to the emitter layer, a collector buffer layer (13) of the first conductivity type, and a collector layer (14, 15) arranged between the collector buffer layer and the base layer. The collector layer includes a first collector layer (14) formed at the side of the base layer and a second collector layer (15) arranged at the side of the collector buffer layer. The first collector layer is a semiconductor layer having an impurity concentration lower than that of the base layer. The second collector layer is a semiconductor layer of the second conductivity type having an impurity concentration higher than that of the first collector layer.

    摘要: Bipolar transistors are made by forming a base window through a dielectric layer overlying a substrate. In the wall of the base window a polysilicon layer is exposed. Subsequent processing involves the forming of various sidewall spacers within the base window to define the base and emitter regions. Since spacer formation requires no lithographic processing, there is no need to define very small features, such as the emitter, lithographically. The smallest feature which needs to be defined lithographically is the original base window which may be between 1 and 2 microns for emitter widths of 0.5 um or less.

    摘要: A semiconductor device comprising a p⁺ region (2) and an n⁺ region (3) forming a p⁺/n⁺ homojunction in a semiconductor layer (2, 3) formed between a semiconductor substrate (1) and a cap semiconductor layer (4) both of a wider band gap material than that of the semiconductor layer (2, 3). The p⁺ region (2) and the n⁺ region (3) are respectively provided with contact regions (6, 5), and a gate electrode (7) is formed on the cap layer (4). A tunneling current can flow between a two-dimensional electron gas (10) and a two-dimensional hole gas (11) induced at the heterojunction boundaries of the double heterojunction structure owing to an electric field applied to the semiconductor layer (2, 3). A buffer layer (71) of wide band gap semiconductor material can be further provided between the semiconductor substrate (1) and the semiconductor layer (2, 3) for reducing the leakage currents.

    摘要: Bipolartransistorstrukturen vom Typ npn mit extrem fla­chen Emitter/Basis-Zonen (2, 4) werden erhalten, wenn die Bildung der aktiven Basiszone (2) unter der Emitter­zone (4) neben der Bor-Ionenimplantation mit einer Phos­phor-Ionenimplantation mit etwas größerer Eindringtiefe erfolgt (Figur 1). Hierdurch wird der "Channeling"-­Schwanz des Bordotierungsprofils umdotiert und die Basis­weite W B drastisch reduziert. Die Erfindung wird bei der Herstellung hochintegrierter CMOS-Schaltungen verwendet.
