Patent ID: 6899544

Claim:
An integrated circuit device comprising: a substrate; a first pad row having a plurality of first pads provided in a first direction on said substrate; a second pad row having a plurality of second pads provided in said first direction on said substrate; a third pad row having a plurality of third pads provided in said first direction on said substrate, said first to third pad rows being apart from each other in a second direction orthogonal to said first direction, and said second pad row being sandwiched by said first and third pad rows; a plurality of first leads provided on said substrate and respectively connected to said plurality of first pads; a plurality of second leads provided on said substrate and respectively connected to said plurality of second pads; a plurality of third leads provided on said substrate and respectively connected to said plurality of third pads; and an integrated circuit provided at that position on said substrate at which said integrated circuit and said second pad row sandwich said third pad row, and connected to said first leads, said second leads and said third leads, wherein a first slanted side extending in a direction oblique to said first direction is formed at each of said second pads at that corner which lies on that side of said third pad row, a second slanted side extending in a direction oblique to said second direction is formed at each of said third pads at that corner which faces said first slanted side, and each of said first leads has a first slanted portion provided between said first slanted side and said second slanted side and extending in a direction oblique to said first direction.
