Abstract
In a method of forming an integrated circuit array having a capacitance formed by a pn-junction and separated from other components by a pn-junction, semiconductor areas are provided which connect that zone of the two semiconductor zones forming the pn-junction of the capacitance that extends deeper into the semiconductor element than the other of the two semiconductor zones forming the pn-junction of the capacitance electrically to that zone of the two semiconductor zones forming the separating pn-junction that faces away from the capacitance.
