Patent ID: 7906848

Claim:
A semiconductor device comprising a semiconductor chip of a planer rectangular shape, wherein the semiconductor chip includes: a semiconductor substrate having a semiconductor element formed on a main surface thereof and patterned into the planer rectangular shape; a first insulator formed on the main surface of the semiconductor substrate; a first wire formed by filling an electric conductive film in a first trench portion formed in the first insulator; a second insulator formed on the first insulator and the first wire; and a third insulator formed on the second insulator so as to contact the second insulator, wherein the second insulator has a higher Young's modulus compared to the third insulator, wherein the second insulator is made of a SiN film, a SiCN film, a SiCO film, or a stacked film thereof, wherein the third insulator is a film formed closest to the semiconductor substrate side of films made of a material having a relatively lower dielectric constant than a silicon oxide film deposited by CVD method, wherein the second insulator is removed in only a first region corresponding to a planar outer periphery of the semiconductor chip, and wherein the semiconductor chip is sealed by a resin.
