Classification: CPC H | IPC H

Claim 2:
3. The IC device of claim 1, further comprising:
a first metal layer over the at least one active region, and comprising the at least one first IO pattern and an extension pattern, the extension pattern contiguous to the at least one first IO pattern and extending from inside the boundary of the circuit region to outside the boundary;
a second metal layer over the at least one active region, and comprising a further pattern which extends along a fourth direction to overlap the extension pattern; and
a via electrically coupling the further pattern to the extension pattern,
wherein
the fourth direction is oblique to both the first direction and the second direction, and is transverse to the third direction, and
the further pattern is an IO pattern of a further circuit region.
