Abstract:
1. A semiconductor device comprising: a substrate; conductive members provided in an upper portion of the substrate or above the substrate to extend in one direction; an interlayer insulating film provided on the substrate and the conductive members; and a plurality of contacts provided in the interlayer insulating film, in a first region on the substrate, the contacts being located at some of lattice points of an imaginary first lattice, in a second region on the substrate, the contacts being located at some of lattice points of an imaginary second lattice, the second lattice being different from the first lattice, and each of the first lattice and the second lattice including some of the lattice points located on the conductive members or on an extension region extended in the one direction of the conductive members, a position of each of the lattice points located on the conductive members and the extension region in the one direction being periodically displaced based on every n consecutively-arranged conductive members, n being a natural number.
