ABSTRACT:
In a semiconductor device having a metal electrode on a crystalline semiconductor surface, the metal electrode includes first portions electrically and mechanically connected to the surface and second portions mechanically separated from the surface and having configurations that easily deform. These first and second portions are alternatingly arranged on the surface. Accordingly, stress applied to the semiconductor beneath the electrode is reduced and deformation of the semiconductor element due to thermal stress is prevented, thereby preventing deterioration of element characteristics.
