Abstract: Fabrication of a bipolar transistor on a monocrystalline silicon substrate (1) with a first type of conductivity incorporates a stage of carbon implantation at the surface of the substrate followed by annealing, before epitaxial formation of the base of the transistor in the form of a multi-layer (T) semiconductor incorporating at least one lower layer (4), a median heavily doped layer (5) with a second type of conductivity and a upper layer (6) which contacts a heavily doped emitter (9) with the first type of conductivity. An Independent claim is included for a hetero-junction bipolar transistor produced.

Abstract: The x-ray diffraction spectrum of the structure is measured. The diffraction spectra of a monocrystalline silicon substrate, and a monocrystalline silicon substrate completely covered with a layer of monocrystalline SiGe, are simulated. Simulated spectra are added, assigning weights (a) and (1-a), to obtain a summed spectrum. The summed spectrum is compared with the measured spectrum. Simulation parameters and weighting (a) are adjusted, to reduce the difference between summed, and measured spectra.

Abstract: Built-in capacitance (C1) on a silicon substrate (7) comprises a first highly doped polysilicon electrode (1), a thin layer (3) of silicon oxide, a second polysilicon electrode (10) and a silicide layer (4) over the second electrode. The second electrode has a high dopant concentration at the interface with the silicon oxide and a relatively low dopant concentration at the interface with the silicide layer. An Independent claim is also included for an integrated circuit, comprising at least one capacitance as above.

Abstract: Une portion monocristalline (1) à base de silicium est réalisée sur un substrat (100), sélectivement dans une zone (101) où un matériau monocristallin est initialement découvert. La portion est réalisée en dehors de zones où la surface (S) du substrat est en matériau isolant (102). La portion monocristalline est formée à partir d'un mélange gazeux comprenant un précurseur de silicium du type hydrure non-chloré, du chlorure d'hydrogène et un gaz porteur. Le procédé permet de réduire une température de chauffage du substrat nécessaire pour former la portion monocristalline par croissance épitaxiale sélective.

Abstract: A vertical bipolar transistor production process comprises epitaxy of a single crystal silicon emitter region in direct contact with the upper layer of a silicon germanium heterojunction base. Production of a vertical bipolar transistor comprises (a) forming an intrinsic collector (4) on an extrinsic collector layer buried in a semiconductor substrate (1); (b) forming a lateral insulation region (5) around the upper part of the intrinsic collector and an offset extrinsic collector well (60); (c) forming an silicon germanium heterojunction base above the intrinsic collector (4) and the lateral insulation region (5) by non-selective epitaxy of a multilayer (8) including a silicon germanium layer; and (e) forming an in-situ doped emitter by epitaxy on a window of the surface of the multilayer located above the intrinsic collector to obtain, above the window, a single crystal silicon emitter region in direct contact with the upper layer of the multilayer (8). An Independent claim is also included for a vertical bipolar transistor produced by the above process.
