Patent ID: 11943939
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. The IC device of claim 9, further comprising:
a first ring region over the substrate and surrounding the first core region, wherein the at least one first IO pattern is in the first ring region;
a second core region over the substrate;
a second ring region over the substrate, and surrounding the second core region; and
at least one third IO pattern in the second ring region and configured to electrically couple the second core region to external circuitry outside the second core region,
wherein
the at least one third IO pattern extends along the fourth direction,
the at least one third IO pattern is arranged in a metal layer different from the first metal layer,
the at least one first IO pattern overlaps the at least one third IO pattern, and
the IC device further comprises at least one via electrically coupling the at least one first IO pattern to the at least one third IO pattern.
