Abstract:
An x-y infrared CCD sensor employing the photoelectric effect as in a p-doped semiconductor substrate of silicon with an n.sup.+ pn diode as the infrared sensor element with a three layer structure in the vertical direction in the semiconductor substrate and a n-channel charge coupled device shift register. The device has a metal-oxide-semiconductor storage electrode directly adjacent to the n-region of the three layer structure. The device is manufactured by masked ion implantation with the doping density for the three layer sequence such that the doping density for the layer operating as the emitter is greater than the doping density for the layer operating as a base, which in turn is greater than the doping density for the layer operating as the collector.
Abstract:
The invention relates to a transistor that is provided with a first source/drain area (S/D1), a channel area (KA) adjacent thereto, a second source/drain area (S/D 2) adjacent thereto, a gate dielectric and a gate electrode. A first capacitor electrode (SP) of the capacitor is connected to the first source/drain area (S/D1). An insulating structure entirely surrounds an insulating area of the circuit arrangement. At least the first capacitor electrode (SP) and the first source/drain area (S/D1) are arranged in the insulating area. The second source/drain area (S/D2) and the second capacitor electrode of the capacitor are arranged outside the insulating area. The insulating structure prevents the first capacitor electrode (SP) from loosing charge through leaking currents between charging and discharging of the capacitor. A tunnel barrier (T) which is arranged in the channel area (KA) is part of the insulating structure. A capacitor dielectric (KD) that separates the first capacitor electrode (SP) from the second capacitor electrode is part of the insulating structure.

Abstract:
A voltage-stable sub-.mu.m-MOS transistor for VLSI circuits consist of a low-resistant silicon substrate of a first conductivity type with a high-resistant, thin, epitaxial layer of the first conductivity type situated thereon and on which a gate electrode consisting of polysilicon is disposed. Highly doped source/drain zones of the second conductivity type form a channel region of the first conductivity type. A doping substance concentration, rising in the direction of the substrate, is generated by means of double implantation, whereby the concentration maximum extends to behind the source/drain zones. A method for manufacturing same incorporates steps of forming the several layers, applying a mask, executing a double implantation in the channel region, and forming the gate electrode.

A photo-transistor in MOS thin-film technology operable with alternating voltages is comprised of a semiconductor body (3) composed of polycrystalline silicon having source (4) and drain (5) zones therein spaced apart by an undoped channel region (13) and having a gate electrode (1, 10) separated from the semiconductor body (3) by a SiO.sub.2 layer (2) produced by thermal oxidation. These phototransistors are easily and reproducably produced and are characterized by low threshold voltages and a good transistor characteristic curve. Thus, these photo-transistors are well suited for use as sensor elements, opto-couplers, time-delay elements and as photo-transistors in VLSI circuits.
