Abstract:
Semiconductor component, especially for high voltage applications, with low-doped base region (3) of the first conductivity type (n) extending in the lateral direction (x),two terminal areas (1, 2) which are separated at least by the base region (3) in the lateral direction (x) for connection to electrical contacts (A, K), characterized in that the base material of the base region (3) is silicon (Si), with a dopant concentration of 1012 to 5Ã—1014 cmâˆ’3, the dopant surface concentration (NA) which has been determined by integration of the dopant concentration over the vertical thickness of the base region (3) along the lateral direction (x) being less than 2Ã—1012 cmâˆ’2, and there are compensation layers (6, 6a, 6b, 6c, 7, 7a, 7b, 7c, 8) of the second conductivity type (p) opposite the first conductivity type which extend inside or outside the base region in the lateral direction (x), the lateral length (lK) of the compensation layers being greater than their vertical thickness (d6, d7) and a dopant surface concentration (NA) which has been determined by integration of the dopant concentration over the vertical thickness of a compensation layer along the lateral direction (x) being less than 1Ã—1012 cmâˆ’2.
