A mask inspection method according to the embodiments, original data corresponding to a semiconductor integrated circuit pattern to be formed on a substrate is created. After that, original production simulation which mocks an original production process is performed on the original data to derive information relating to an original pattern shape in the case of forming an original pattern corresponding to the original data on an original. After that, whether or not the information relating to an original pattern shape satisfies a predetermined value decided based on the original production process is determined.

An edge extraction unit extracts vertical and horizontal wiring edges and slanted wiring edges from overall wiring graphics, and a wiring width classification unit executes a scaling process for the overall wiring graphics to classify the wiring graphics into wiring width ranges which are divided by a predefined reference wiring width. A vertical and horizontal wiring edge extraction unit extracts the vertical and horizontal wiring edges which are in contact with graphics classified into the wiring width ranges, and a vertical and horizontal wiring interval verification unit verifies intervals between the vertical and horizontal wiring edges and opposed edges to be verification counterparts based on a vertical and horizontal reference interval for each wiring width range. A slanted wiring edge extraction unit extracts slanted wiring edges which are in contact with graphics classified into the wiring width ranges, and a slanted wiring interval verification unit verifies intervals between the slanted wiring edges and opposed edges to be verification counterparts based on a slanted reference interval for each wiring width range.

According to one embodiment, a semiconductor device includes interconnects extending from a element formation area to the drawing area, and connected with semiconductor elements in the element formation area and connected with contacts in the drawing area. The interconnects are formed based on a pattern of a (n+1)th second sidewall film matching a pattern of a nth (where n is an integer of 1 or more) first sidewall film on a lateral surface of a sacrificial layer. A first dimension matching an interconnect width of the interconnects and an interconnects interval in the element formation area is (k1/2n)×(λ/NA) or less when an exposure wavelength of an exposure device is λ, a numerical aperture of a lens of the exposure device is NA and a process parameter is k1. A second dimension matching an interconnect interval in the drawing area is greater than the first dimension.
