    摘要: Transistor and method of manufacturing a bipolar transistor of the double-polysilicon, heterojunction-base type, in which a semiconducting layer with SiGe heterojunction is formed by non-selective epitaxy on an active region of a substrate and an insulating region surrounding the active region. At least one stop layer is formed on the semiconducting layer above a part of the active region. A layer of polysilicon and an upper insulating layer are formed on the semiconducting layer and on a part of the stop layer, leaving an emitter window free. An emitter region is formed by epitaxy in the emitter window, resting partially on the upper insulating layer and in contact with the semiconducting layer.

    摘要: A vertical bipolar transistor includes a semiconductor substrate, an extrinsic collector layer in the semiconductor substrate, an intrinsic collector on the extrinsic collector, a lateral isolating region surrounding an upper part of the intrinsic collector, an offset extrinsic collector well, a base including a semiconductor region above the intrinsic collector and above the lateral isolating region including at least one silicon layer, and a doped emitter surrounded by the base. The doped emitter may include first and second parts. The first part may be formed from single-crystal silicon and in direct contact with the upper surface of the semiconductor region in a predetermined window in the upper surface above the intrinsic collector. The second part may be formed from polycrystalline silicon. The two parts of the emitter may be separated by a separating oxide layer spaced apart from the emitter-base junction of the transistor.

    摘要: A self-aligned double-polysilicon type bi-polar transistor with a heterojunction base comprises a semiconducting heterojunction region lying over an active region of a semiconductor substrate and over an isolating region delimiting the active region, and incorporating the intrinsic base region of the transistor. An emitter region situated above the active region and coming into contact with the upper surface of the semiconducting heterojunction region. A polysilicon layer forming the extrinsic base region of the transistor, situated on each side of the emitter region and separated from the semiconducting heterojunction region by a separation layer comprising an electrically conducting connection part situated just outside the emitter region. This connection part ensures an electrical contact between the extrinsic base and the intrinsic base.

    摘要: The intrinsic collector of a vertical bipolar transitor is grown epitaxially on an extrinsic collector layer buried in a semiconductor substrate. A lateral isolation region surrounds the upper part of the intrinsic collector and an offset extrinsic collector well is produced. An SiGe heterojunction base lying above the intrinsic collector and above the lateral isolation region is produced by non-selective epitaxy. An in-situ doped emitter is produced by epitaxy on a predetermined window in the surface of the base which lies above the intrinsic collector so as to obtain, at least above the window, an emitter region formed from single-crystal silicon and directly in contact with the silicon of the base.

    摘要: A transistor including a germanium-rich channel. The germanium-rich channel is produced by oxidation of the silicon contained in the silicon-germanium intermediate layer starting from the lower surface of the said intermediate layer. The germanium atoms are therefore caused to migrate towards the upper surface of the silicon-germanium intermediate layer, and are stopped by the gate insulating layer. The migration of the atoms during the oxidation step is thus less prejudicial to the performance of the transistor, since the gate insulator of the transistor has already been produced and is not modified during this step. The migration of the germanium atoms towards the gate insulator, which is immobile, leads to a limitation of the surface defects between the channel and the insulator.
