    • A semiconductor device includes: a semiconductor layer 10; a semiconductor region 15s of a first conductivity type defined on the surface 10s of the semiconductor layer; a semiconductor region 14s of a second conductivity type defined on the surface 10s of the semiconductor layer to surround the semiconductor region 15s; and a conductor 19 with a conductive surface 19s to contact with the semiconductor regions 15s and 14s. The semiconductor layer 10 includes silicon carbide. At least one of the semiconductor region 15s and the conductive surface 19s is not circular. The semiconductor region 15s and the conductive surface 19s are shaped such that as the degree of misalignment between the conductive surface 19s and the semiconductor region 15s increases from zero through one-third of the width of the conductive surface 19s, a portion of the profile of the conductive surface 19s that crosses the semiconductor region 15s has smoothly changing lengths.
    • 半导体器件包括:半导体层10; 限定在半导体层的表面10s上的第一导电类型的半导体区域15s; 限定在半导体层的表面10s上以包围半导体区域15s的第二导电类型的半导体区域14s; 以及具有导电表面19s以与半导体区域15s和14s接触的导体19。 半导体层10包括碳化硅。 半导体区域15s和导电表面19s中的至少一个不是圆形的。 半导体区域15s和导电表面19s被成形为使得当导电表面19s和半导体区域15s之间的未对准程度从零增加到导电表面19s的宽度的三分之一时,轮廓的一部分 穿过半导体区域15s的导电表面19s具有平滑变化的长度。
