ABSTRACT:
A semiconductor device has a plurality of interconnect layers each including a plurality of interconnect lines. The semiconductor device includes a dielectric film (HDP film) formed by means of high density plasma-enhanced CVD and including an edge formed on the side surface of the topmost-layer interconnect lines, a silicon oxide film formed by modifying a SOG film on the HDP film between adjacent two of the topmost-layer interconnect lines in the element forming region, and a passivation film formed to cover the HDP film and the topmost-layer interconnect lines.
