Abstract (en)

[origin: DE19712561C1] An SiC channel area (2) of a semiconductor array comprises bumps (6) running parallel to each other which are formed by misoriented epitaxial growth on its surface (20). The electrical power flow in the channel area (2) is adjusted parallel to the bumps (6). Thus, high charge carrier mobility in the channel area (2) is achieved.
