Abstract
A semiconductor device according to an embodiment, includes a plurality of wires, a first dielectric film, and a second dielectric film. The plurality of wires are arranged above a semiconductor substrate so as to extend in a first direction and aligned via a first cavity. The first dielectric film has a plurality of portions arranged above the plurality of wires so as to extend in a second direction substantially perpendicular to the plurality of wires and aligned along the first direction via a second cavity leading to the first cavity. The second dielectric film is formed above the first dielectric film so as to cover the second cavity.
