SCHOTIKY BARRIER PIODE

摘要

The diode has an electrode for high speed operation and for mechanical stress reduction caused by ultrasonic welding. A protecting layer (3) is covered on the first conduction type layer (2) except some area. A second conduction type layer (4) is formed by selective diffusion in the diffusion layer. A metal layer (6) having contact resistance is formed on the second conduction type layer (4). A metal layer (7) forming a schottky barrier and deposited from surface of the second conduction type layer (4) to the exposed surface of the first conduction type layer (2) is formed.
