    摘要: The invention relates to a method for fabricating a transistor structure, comprising at least a first and a second bipolar transistor having different collector widths.The invention is distinguished by the fact that all junctions between differently doped regions have a sharp interface. In this case, by way of example, a first collector region 2.1 is suitable for a high-frequency transistor with high limiting frequencies fT and a second collector region 2.2 is suitable for a high-voltage transistor with increased breakdown voltages.

    摘要: The invention relates to a method for producing a bipolar transistor. A semiconductor substrate is provided that encompasses a collector area of a first conductivity type, which is embedded therein and is bare towards the top. A monocrystalline base area is provided and a base-connecting area of the second conductivity type is provided above the base area. An insulating area is provided above the base-connecting area and a window is formed in the insulating area and the base-connecting area so as to at least partly expose the base area. An insulating sidewall spacer is provided in the window in order to insulate the base-connecting area. An emitter layer which forms a monocrystalline emitter area above the base area and a polycrystalline emitter area above the insulating area and the sidewall spacer is differentially deposited and structured, and a tempering step is carried out.

    摘要: A memory cell configuration in a semiconductor substrate is proposed, in which the semiconductor substrate is of the first conductivity type. Trenches which run parallel to one another are incorporated in the semiconductor substrate, and first address lines run along the side walls of the trenches. Second address lines are formed on the semiconductor substrate, transversely with respect to the trenches. Semiconductor substrate regions, in which a diode and a dielectric whose conductivity can be changed are arranged, are located between the first address lines and the second address lines. A suitable current pulse can be used to produce a breakdown in the dielectric, with information thus being stored in the dielectric.

    摘要: A method for fabricating a dopant region is disclosed. The dopant region is formed by providing a semiconductor substrate that has a surface. An electrically insulating intermediate layer is applied to the surface. A doped semiconductor layer is then applied to the electrically insulating intermediate layer, the semiconductor layer being of a first conductivity type and contains a dopant of the first conductivity type. A temperature treatment of the semiconductor substrate at a predefined diffusion temperature is performed, so that the dopant diffuses partially out of the semiconductor layer through the intermediate layer into the semiconductor substrate and forms there a dopant region of the first conductivity type. The electrical conductivity of the intermediate layer is modified, so that an electrical contact between the semiconductor substrate and the semiconductor layer is produced through the intermediate layer.

    摘要: The DRAM cell arrangement comprises, per memory cell, a vertical MOS transistor whose first source/drain region is connected to a storage node of a storage capacitor, whose channel region (3) is annularly enclosed by a gate electrode (13) and whose second source/drain region is connected to a buried bit line. The DRAM cell arrangement is produced using only two masks, with the aid of a spacer technique, with a memory cell area of 2F.sup.2, where F is the minimum structure size which can be produced using the respective technology.
