ABSTRACT:
Improved epitaxial resistor for use in integrated circuits in which for the lateral boundary boundary zones projecting beyond the isolation zones are provided at the surface with a depth of penetration which is smaller than the thickness of the epitaxial layer. Such resistors can be manufactured with a considerably smaller spread of the resistance value than the so far usual epitaxial resistors.
