Abstract
PURPOSE:To enable to allow an insulating film to occur a defect such as pinholes or the like in the partial region at the producing time by electrically isolating a semiconductor region directly under wires of different voltages aligned in parallel with each other on a semiconductor substrate at every wire. CONSTITUTION:Regions 5a, 5b of a semiconductor substrate directly under wires 4a, 4b of different voltages provided on a surface insulating film 3 on a semiconductor substrate 1 are electrically insulated via an isolation 2 in advance in an oxidized film or a P-N junction or the like. In this manner, a leakage for shortcircuiting the wires 4a, 4b through the substrate from the pinholes 6 occured at the film 3 is prevented, thereby improving the yield and the reliability of an IC.
