摘要： A trench DMOS transistor device that comprises: (a) a substrate of a first conductivity type; (b) an epitaxial layer of first conductivity type over the substrate, wherein the epitaxial layer has a lower majority carrier concentration than the substrate; (c) a trench extending into the epitaxial layer from an upper surface of the epitaxial layer; (d) an insulating layer lining at least a portion of the trench; (e) a conductive region within the trench adjacent the insulating layer; (f) a body region of a second conductivity type provided within an upper portion of the epitaxial layer and adjacent the trench; (g) a source region of first conductivity type within an upper portion of the body region and adjacent the trench; and (h) one or more low resistivity deep regions extending into the device from an upper surface of the epitaxial layer. The low resistivity deep region acts to provide electrical contact with the substrate, which is a common drain region for the device. By constructing a trench DMOS transistor device in this fashion, source, drain and gate contacts can all be provided on a single surface of the device.

摘要： A wafer-level process for fabricating a plurality of passivated semiconductor devices comprising the steps of providing a semiconductor wafer on that at least one p-n junction is formed, Cutting a plurality of grooves in said wafer to expose said at least one p-n junction, wherein each of said grooves extends partly through the wafer and has a depth that is enough to expose said at least one p-n junction, applying a passivating material into said grooves and curing the material. The grooves can be formed by using a disc saw having a blade, by performing a sandblasting operation within a controlled operation time, or by performing a photolithographically chemical etching process. The passivating material is either screen-printed or pin-dispensed into the grooves. A dicing operation can be subsequently proceeded to divide the wafer into individual chips for subsequent fabrication into completed semiconductor devices.

摘要： A leaded semiconductor device package for nonsoldering assembling is disclosed. In the package of the invention, both leads of a semiconductor device package are flattened, cut and bent by automatic machines on the bais of conventional packaging process. Unlike a conventional semiconductor device package which is electrically connected to a circuit by soldering, the flattened and bent parts of both leads of the semiconductor device package can be electrically connected to a circuit by elastically contacting and directly assembling without soldering.
