Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device securing a low threshold and higher voltage resistance, even if a Schottky electrode is not installed.  <P>SOLUTION: A cathode layer 1 of type N<SP>+</SP>is formed, in junction with a cathode electrode 100 and a drift layer 2 of type N in low impurity concentration is formed, in junction with the cathode layer 1. A plurality of trenches 4a, 4b are arranged on the upper surface of the drift layer 2, keeping a predetermined interval. Embedded electrodes 5a, 5b are respectively formed within the trenches 4a, 4b via insulating films 6a, 6b. An inter-trench region 7 is formed between the neighboring trenches. In addition, a universal contact layer 3, jointed with an anode electrode 200, is formed in junction with the inter-trench region 7, by alternately arranging a P<SP>+</SP>-layer 31 at a high impurity concentration and an N<SP>+</SP>-layer 32 at a high impurity concentration. Since the potential of the inter-trench region 7 under the thermal equilibrium condition is adjusted, the difference in the potential, from that of the drift layer 2 under the thermal equilibrium condition, is lower than built-in voltage that depends on the band gap of a semiconductor material used.  <P>COPYRIGHT: (C)2011,JPO&INPIT
