An electrical resistor integrated in an integrated semiconductor circuit to have a useful resistor with two spaced-apart useful resistor terminal contact regions and a useful resistor region of semiconductor material located therebetween; and an auxiliary resistor having two spaced-apart auxiliary resistor terminal contact regions and an auxiliary resistor region located therebetween. The auxiliary resistor region is formed in semiconductor material located underneath the useful resistor region; an intermediate region is provided between the useful resistor region and the auxiliary resistor region; the useful resistor region and the auxiliary resistor region have a substantially identical topography; and the auxiliary resistor terminal contact regions and the useful resistor terminal contact regions are wired in such a manner that, on connection of the semiconductor circuit to a supply voltage source, the auxiliary resistor terminal contact region at one end of said auxiliary resistor region and the auxiliary resistor terminal contact region at the other end of said auxiliary contact region each have the same potential difference with respect to the respectively adjacent useful resistor terminal contact region.
