Very high resistance values may be necessary in integrated circuits, for example in the gigaohm range, for example for realizing RC times of 1 ms to 1 s. Such resistance values cannot or substantially not be realized by known methods in standard i.c. processes because of the too large space occupation. In addition, kno...
