Patent ID: 7385289

Claim:
A semiconductor device, comprising: a semiconductor substrate having formed thereon a semiconductor element; a first wiring layer formed on said semiconductor substrate above an operating region where said semiconductor element is formed, said first wiring layer being electrically connected to said operating region; a second wiring layer formed on said semiconductor substrate above said first wiring layer; and a bonding pad to be electrically connected to an external connection terminal, formed on said semiconductor substrate above said second wiring layer, at least a part of said bonding pad being located above said operating region, wherein said second wiring layer includes a plurality of wirings formed in the region under said bonding pad, a predetermined wiring of said plurality of wirings is electrically connected to said bonding pad, and an insulating film is provided for insulating said bonding pad from other wirings than the predetermined wiring among said plurality of wirings so that a plurality of wirings of the second wiring layer, which are located directly under the bonding pad, are insulated from the bonding pad by the insulating film, wherein said insulating film is formed over said other wirings so as to directly contact the bonding pad; said other wirings provided parallel to the edges of said bonding pad are not formed in regions right under the edges, and wherein at least one of said other wirings of said second wiring layer that is insulated from said bonding pad is electrically connected to the first wiring layer by way of a via defined in an insulator located between said first and second wiring layers so that the at least one of the other wirings of said second wiring layer is electrically connected to both (a) the first wiring layer, and (b) the operation region by way of the first wiring layer; said insulating film is made up of an inorganic insulating film only, so that no organic insulating film is provided between the other wirings and the bonding pad; and wherein a group of the other wirings of the second wiring layer is not electrically connected to any wiring layer thereunder, whereas said one of the other wirings of the second wiring layer is electrically connected to the first wiring layer which is provided thereunder.
