Patent ID: 7696607

Claim:
A semiconductor device, comprising: a circuit region having a function element formed on a semiconductor substrate; a scribe region located between the circuit region and another circuit region formed spaced from the circuit region, the scribe region including a cutting region cut by a dicing blade and non-cutting regions provided at both sides of the cutting region and not cut by the dicing blade; a first interlayer insulating film formed in the scribe region on the semiconductor substrate; a first dummy pattern made of conductive material and formed in the first interlayer insulating film in the cutting region; and a second dummy pattern made of conductive material and formed in the first interlayer insulating film in each of the non-cutting regions, wherein a ratio, per unit area, of the area of the first dummy pattern to the area of the cutting region is lower than the ratio, per unit area, of the area of the second dummy pattern to the area of the non-cutting regions.
