Abstract
In a highly integrated semiconductor wiring structure having a plurality of wiring layers and a self-aligned contact hole formed therebetween, the wiring layer is formed such that a portion where a contact hole will be formed is formed to a first wiring width and a remaining portion is formed to a second wiring width being wider than the first wiring width. In the method for manufacturing such a structure, the contact hole is formed in self-alignment fashion, and thus, a short which may occur due to misalignment can be prevented.
