摘要： A schottky diode includes a drift region of a first conductivity type and a lightly doped silicon region of the first conductivity type in the drift region. A conductor layer is over and in contact with the lightly doped silicon region to form a schottky contact with the lightly doped silicon region. A highly doped silicon region of the first conductivity type is in the drift region and is laterally spaced from the lightly doped silicon region such that upon biasing the schottky diode in a conducting state, a current flows laterally between the lightly doped silicon region and the highly doped silicon region through the drift region. A plurality of trenches extend into the drift region perpendicular to the current flow. Each trench has a dielectric layer lining at least a portion of the trench sidewalls and at least one conductive electrode.

A gate trench extends through the body region and terminating within the semiconductor region. A source region of the second conductivity type extends in the body region adjacent the gate trench. The source region and an interface between the body region and the semiconductor region define a channel region therebetween which extends along the gate trench sidewall.

A non-active perimeter region surrounds the active area, and includes at least one p ring surrounding the active area. One end of at last one of the strips of p pillars extending immediately adjacent an edge of the active area terminates at a substantially straight line at which one end of each of the remainder of the strips of p pillars also end. The straight line extends perpendicular to the length of the active area along which the strips of n and p pillars extend.

摘要： A gate electrode control structure of an MOS-gated semiconductor device includes four doped regions including a first (source) region forming a first P-N junction with an enclosing composite region comprising a second, lightly doped (channel) region wholly enclosing a third heavily doped (body) region partly enclosing the first region, and a fourth (drain) region forming a P-N junction with the third region. The gate electrode control structure is fabricated using known gate electrode self-alignment doping processes but wherein, in the process for forming the third heavily doped region, a spacer layer is provided on the gate electrode for defining a spacing between the third region and the channel region with an improved degree of precision.
