Abstract:
An electrical resistor integrated in an integrated semiconductor circuit, comprising:a useful resistor having two spaced-apart useful resistor terminal contact regions and a useful resistor region of semiconductor material located therebetween; an auxiliary resistor having two spaced apart auxiliary resistor terminal contact regions and an auxiliary resistor region located therebetween, said auxiliary resistor region formed in semiconductor material located underneath said useful resistor region; and said useful resistor region (17, 19; 69, 71; 89, 91) and said auxiliary resistor region (13; 67) have a substantially identical topography; and said auxiliary resistor terminal contact regions and said 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.
