Abstract:
The invention relates to a semiconductor component comprising a first main terminal (40); a second main terminal (80); a gate terminal (70) for controlling the current between the main terminals (40, 80), a first diode device (100) which can be switched between the first gate (40) and the gate terminal (70) and whose first breakdown voltage is such that the first diode device short-circuits the first main terminal (40) with the gate terminal (70), hereby switching on the semiconductor component, when the voltage that drops off over the first diode device (100) exceeds a certain predetermined value. The first diode device (100) is connected to the control gate (70) in an integrated manner and has an external contacting area (120) for connecting to the first main terminal (40).
Abstract:
The invention relates to a method for producing a body area for a vertical MOS transistor array in a semiconductor body, wherein the body area has at least one channel region disposed between the source area and the drain area and borders on a gate electrode. A first implantation of doping material is effected in the semiconductor body, wherein the maximum of doping material of the first implantation is placed in the back part of the channel region (11) within the semiconductor body. At least a second implantation of doping material is then effected with a smaller dose than in the first implantation, wherein the maximum of doping material of the second implantation lies within the semiconductor body below the maximum of doping material of the first implantation. Subsequently, the doping material is diffused off.
Abstract:
Production of a body area (9) of first conductivity type comprises implanting a doping material of first conductivity type into a semiconductor body followed by implanting a doping material of second conductivity type having a lower dose than the first implantation step, and then diffusion of the doping material. Production of a body area (9) of first conductivity type comprises implanting a doping material of first conductivity type into a semiconductor body followed by implanting a doping material of second conductivity type having a lower dose than the first implantation step. The body area has at least one channel region (11) arranged between a source region (10) and a drain region (2, 3) of second conductivity and bordering a gate electrode (5). The body area and the source region extend from a first surface (14) into the semiconductor body, and the drain region extends from a second surface (15) into the semiconductor body. The dosage of the first implantation is 10-1000 times larger than that of the second implantation.
Abstract:
A semiconductor component with a pn junction comprises a semiconductor body comprising a front side and an edge region. A pn junction is formed fashion in curved fashion in the edge region of the semiconductor body. An edge structure comprising depressions is also provided in the edge region of the semiconductor body. The depressions may comprise, for example, a number of capillaries which extend into the semiconductor body proceeding from the front side of the semiconductor body. In one suitable embodiment, the capillaries may be filled with a dielectric
Abstract:
The first and second surfaces (3, 4) of a first wafer (1) are recessed (2, 5) forming penetrations between them, over the entire first surface of the first wafer. A temperature-stable, detachable connection (21) is formed between them, with spacing layers (13-15) of dielectric, uniting the first surface of the first wafer with a first surface of the second wafer, by wafer-bonding connection. An Independent claim is included for a corresponding method of forming a detachable, highly-temperature stable bond between two wafers.
Abstract:
The component has a semiconducting body (1) of one conductor type contg. a body zone (2) of the opposite conductor type and at least one field plate (4) on an insulating coating (5,6) on the semiconducting body and essentially in a region outside the pn-junction defined by the body zone and the semiconducting body. The body zone has an extension zone (10) of the other conductor type formed by additional doping that extends in the semiconducting body until beneath the insulating coating at a distance from the surface of the semiconducting body.
