Patent ID: 7692315

Claim:
A semiconductor device, comprising: an element region including a wiring structure in a low dielectric constant insulating film; and a pad region electrically connecting said element region and the outside, in which the low dielectric constant insulating film is formed in association with in said element region, wherein an occupied density of a plurality of first connection holes formed in the low dielectric constant insulating film in said pad region is higher than an occupied density of a second connection hole in any of portions of the wiring structure in said element region, wherein a Young's modulus of the low dielectric constant insulating film is 20 GPa and below, wherein the plurality of first connection holes are formed in such a manner to be distributed substantially evenly in said pad region, and wherein a lattice shaped wiring electrically connecting said element region and the outside is formed above the low dielectric constant insulating film in said pad region.
