Abstract
A semiconductor device fabrication process includes forming a Schottky layer, a cap layer covering the surface of the Schottky layer, and a Schottky electrode of a two-level structure having a lower portion that penetrates through the cap layer and reaches the Schottky layer, and having an upper portion larger than the lower portion in cross-sectional area and that overlies the cap layer. With this construction, surface defects are unlikely to occur, so that a highly reliable semiconductor device can be fabricated.
