1. A semiconductor device comprising:

  • a semiconductor substrate having at least two resistor elements formed therein, wherein said resistor elements formed therein have a specific resistance ratio relative to each other;

    an insulation layer formed on a major surface of said semiconductor substrate;

    a circuit wiring layer formed on said insulation layer, covering a portion of said insulation layer which corresponds to at least one of said resistor elements; and

    a dummy wiring layer formed on said insulation layer, covering that portion of said insulation layer which corresponds to the resistor element or elements not covered by said circuit wiring layer, and wherein said circuit wiring layer causes less stress on said resistance element not covered by said circuit wiring layer than on said resistance element covered by said circuit wiring layer, said resistance ratio of said resistance elements formed therein being stress-dependent.
