    摘要: A semiconductor device (10,50) is disclosed which can accommodate a negative voltage on its source using a P-type substrate (12) which is connected to ground potential. A first embodiment illustrates a device which can handle high voltage applications as well as a negative voltage applied to the source. A drain contact region (29) is recessed by a dimension (X) from a first insulated region (18). The dimension (X) provides for an optimum distance for high voltage applications while avoiding lateral surface punch-through. A second embodiment illustrates a gate structure (52) having a shape which surrounds a drain contact region (62) and accommodates a high voltage application while also eliminating the lateral surface punch-through. The drain contact region (62) is formed in a P-type region (20) centered inside the gate structure (52).

    摘要: A method of forming a semiconductor device (10, 40, 45, 50) forms a plurality of P and N stripes (16,17) within a first region (12) that is formed with an opposite conductivity to a substrate (11). The plurality of P and N stripes assist in providing a low on-resistance. A portion (15) of the first region underlies the P and N stripes and protects the semiconductor device from high voltages applied to the drain. A base layer (41) and a cap layer (48) further reduce the on-resistance of the semiconductor device.

    摘要: A method of manufacturing a semiconductor wafer having at least one device trench extending to a first depth position includes providing a semiconductor substrate having first and second main surfaces and a semiconductor material layer having first and second main surfaces disposed on the first main surface of the semiconductor substrate and determining an etch ratio. The least one device trench and at least one monitor trench are simultaneously formed in the first main surface of the semiconductor material layer. The at least one monitor trench is monitored to detect when it extends to a second depth position. A ratio of the first depth position to the second depth position is generally equal to the etch ratio.

    摘要: A semiconductor device (10, 40) is formed to have a well (19) in a substrate (11). The well and the substrate have the same doping type, for example both P-type or both N-type. Low resistance contact regions (26, 27) of a second conductivity type are formed to at least abut the well. A drain (17) is formed within one low resistance contact region. A source (12) is formed in the substrate and laterally displaced from the other low resistance contact region. A buried layer (21, 22, 23) is formed laterally across the well.

    摘要: A method and system for creating 3D laser-induced images of a body or bodies suspended in air within a transparent material by way of using a scanner (e.g., a laser scanner) to optically scan an environment and stop action. The same 3D data may be utilized construct portraits of individuals through 3D laser etching, 3D laser cutting, 3D printing/rendering (or any form of rapid prototyping). Multiple scanners such as scanners 102, 104, 106 and 108 can be utilized to capture a complete person three dimensionally—laser scans on all X, Y, Z planes, thereby enabling synchronizing scans. Such an approach further enables the construction of a complete three-dimensional data model from multiple data.
