    摘要: A portable computer having a display unit coupled to a base. The display unit includes an exterior display case, a screen, one or more liquid crystal display (LCD) panels, display electronics and a light source. The light source is a tubular shaped lamp which extends along a length of the display case and is held in place by a harness at one end of the display case. A section of the display case is an independently movable reflector, coated with a light reflective mirrored finish that distributes light evenly along the LCD panel surface. The computer has a storage mode and an active mode. When in active mode, the reflector is inclined and light from the light source reflects unto the LCD panel within the case. In storage mode, the reflector is closed and no light is reflected unto the LCD panel.

    摘要: A top drain trench based RESURF DMOS (reduced surface field double diffused MOS) transistor structure provides improved RDSon performance by minimizing transistor cell pitch. The transistor includes a gate, a source and drain. The trench may include a nonuniform dielectric lining. A drain drift region partially surrounds the trench. Current flows laterally enabling multiple trench based RESURF DMOS transistors to be formed on a single semiconductor die. The addition of an isolation region to electrically isolate the source from the substrate allows the power transistor to be incorporated into high side driver applications as well as other application mandating electrical isolation between the source and ground.

    摘要: A high voltage power transistor cell is developed that provides improved RDSon performance without sacrificing breakdown performance through utilization of trench based transistor technology. A source, drain and trench are formed within a substrate. A gate is formed on the surface over a spacing between the source and the trench. A drift region is formed around the trench. An isolation region may optionally be added allowing electrical isolation between the source and the substrate. The lateral current flow feature allows multiple high voltage power transistors, electrically isolated from one another, to exist on a single semiconductor chip. The drift region formed around the trench provides RESURF transistor characteristics without sacrificing die area.

    摘要: A transistor device (10) includes an epitaxial layer (14) formed on a semiconductor substrate layer (12). A base layer (16) is formed on the epitaxial layer (14) and a source layer (18) is formed on the base layer (16). A trench region (22) is formed extending through the source layer (18), the base layer (16), and the epitaxial layer (14) and into the semiconductor substrate layer (12). An oxide layer (24) is formed on the source layer (18) and on the internal walls of the trench region (22) such that the oxide layer (24) is wider at the bottom of the trench region (22) than at the top in order to handle high voltage applications. A gate layer (26) is formed within the trench region (22) on the oxide layer (24). The gate layer (26) causes a drift region formed within the epitaxial layer (14) to fully deplete under full rated blocking conditions, decreasing the drift region component of the on-resistance which is the dominant parameter in very high voltage devices.
