Abstract

Official abstract text for this publication.

According to one embodiment, a first core pattern is formed in a wiring portion on a process target film and a second core pattern, which is led out from the first core pattern and includes an opening, is formed in a leading portion on the process target film, a sidewall pattern is formed along an outer periphery of the first core pattern and the second core pattern and a sidewall dummy pattern is formed along an inner periphery of the opening of the second core pattern, the first core pattern and the second core pattern are removed, and the process target film is processed to transfer the sidewall pattern and the sidewall dummy pattern.

First claim

Opening claim text (preview).

What is claimed is: 1. A semiconductor device comprising: a plurality of wires formed in a wiring portion on a semiconductor substrate to be parallel to each other at substantially a constant pitch; a plurality of leading lines that are led out from the wires, respectively, and are formed in parallel with each other in a leading portion on the semiconductor substrate at a pitch larger than the wires; dummy leading lines that are formed in the leading portion on the semiconduct…
