Abstract
Abstract The present invention sets forth an integrated circuit (IC) device wherein the IC chip includes peripheral circuits, such as input/output circuits, which are arranged non-perpendicular with respect to the rectangular shape of the active area of the IC. This structure permits positioning some of the terminal bond pads closely adjacent the corners of the chip without overlap of adjacent circuits.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
An integrated circuit chip of substantially rectangular shape having peripheral edges, a substantially rectangular area within said chip containing an integrated circuit spaced from said peripheral edges, a plurality of terminal bond pads disposed adjacent said peripheral edges of said chip, a plurality of peripheral circuits which interconnect said terminal bond pads to active elements of said integrated circuit, each of which is arranged in a generally elongated shape having a longitudinal axis and being disposed within said chip between a side of said rectangular area and a respective each of said terminal bond pads, at least one of said terminal bond pads being adjacent a corner of said chip, wherein each said longitudinal axis forms an angle with said side which is other than 90 degrees.
Claim 2
Dependent Claim
127 words
An integrated circuit chip of substantially rectangular shape having peripheral edges, a substantially rectangular area within said chip containing an integrated circuit spaced from said peripheral edges, a plurality of terminal bond pads disposed adjacent said peripheral edges of said chip, a plurality of peripheral circuits which interconnect said terminal bond pads to active elements of said integrated circuit, each of which is arranged in a generally elongated shape having a longitudinal axis and being disposed within said chip between a side of said rectangular area and a respective each of said terminal bond pads, at least one of said terminal bond pads being adjacent a corner of said chip, wherein each said longitudinal axis forms an angle with said side which is other than 90 degrees.
Claim 3
Dependent Claim
23 words
The integrated circuit chip set forth in claim 1 wherein each of said longitudinal axes forms substantially the same angle with said side.
Claim 4
Dependent Claim
23 words
The integrated circuit chip set forth in claim 2 wherein said angle is less than 90 degrees but greater than about 45 degrees.
Claim 5
Dependent Claim
49 words
The integrated circuit chip as set forth in claim 1 wherein said plurality of peripheral circuits includes first and second peripheral circuits, the longitudinal axis of said first circuit forming an angle with said side that is less than that formed by the longitudinal axis of said second circuit.
Claim 6
Dependent Claim
23 words
The integrated circuit chip as set forth in claim 4 wherein said first peripheral circuit is disposed adjacent said corner of said chip.
Claim 7
Dependent Claim
24 words
The integrated circuit chip as set forth in claim 5 wherein said angle is less than 90 degrees but greater than about 45 degrees.
