PURPOSE:To use adjacent terminals of four terminals as pairs on incorporation into a circuit, and to facilitate soldering and the like by forming a wiring electrode connecting other two element regions onto a high molecular group resin between a Schottky electrode and an ohmic electrode in one element region. CONSTITUTION:There are isolation grooves 10 shaped so as to part an N<++> type impurity 3 up to a section under the impurity 3 from the surface of a substrate 1 in order to partition element regions 11a, 11b, 11c, 11d, and the side surfaces of the grooves 10 are made perpendicular to the surface of the substrate 1. A high molecular group resin 12 such as polyimide formed as an insulating film on the upper surface of the substrate 1 is also introduced into the isolation grooves 10..., thus ensuring element isolation by the isolation grooves 10.... A wiring electrode 7a connecting an ohmic electrode 6 in a region 11c and a Schottky electrode 5 in an element region 11a is shaped onto the high molecular group resin 12 between a Schottky electrode 5 in an element region 11d and an ohmic electrode 6, thus connecting four diodes in a crossed manner. |
