This article describes a semiconductor resistor, consisting of a stripe-formed resistor zone having contacts at both ends, the zone being formed by re-doping a corresponding region of a semiconductor layer. The specified semiconductor resistor is designed as P-resistor zone B in an N-epitaxial layer 2 applied on a P-substrate 1. Fig. 1 depicts the structure of the complete semiconductor resistor in a plan view. The effective width B' of the semiconductor resistor is determined by limitation zones A externally overlapping resistor zone B and being of the opposite conductivity type and of a higher absolute concentration. First, as shown by the sectional view I-II of the structure of Fig. 1 in Fig.
