  • Patent number: 5985745
    Abstract: A semiconductor device fabricating method is capable of securing an increased margin for absorbing an error in aligning a viahole with an underlying wiring layer when forming a viahole in a layer insulating film to connect an upper wiring layer overlying the layer insulating film and a lower wiring layer underlying the layer insulating film to enable the miniaturization of a pattern and the miniaturization of the semiconductor device. The semiconductor device fabricating method forms a first Si.sub.3 N.sub.4 film between a first wiring layer and a second wiring layer, and a second layer insulating film, a third layer insulating film and a fourth layer insulating film all of SiO.sub.2 over the second wiring layer. When forming a third viahole through the layer insulating films so as to reach the second wiring layer, the layer insulating films are etched in a high SiO.sub.2 /Si.sub.3 N.sub.4 selectivity of about twenty.
