Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. The IC device of claim 1, wherein the at least one first IO pattern comprises a plurality of first IO patterns, the IC device further comprising:
a first metal layer over the at least one active region, and comprising the plurality of first IO patterns;
a second metal layer over the at least one active region, and comprising a further pattern which extends along a fourth direction oblique to both the first direction and the second direction, the fourth direction transverse to the third direction;
an extension pattern in the first metal layer, the extension pattern contiguous to one first IO pattern among the plurality of first IO patterns and extending from inside the boundary of the circuit region to outside the boundary to overlap the further pattern;
a first via electrically coupling the further pattern to the extension pattern;
a third metal layer over the at least one active region, and comprising an access pattern which extends along the first direction or the second direction from outside the boundary of the circuit region to inside the boundary to overlap a further first IO pattern among the plurality of first IO patterns; and
a second via electrically coupling the access pattern to the further first IO pattern.
