Patent ID: 11901283
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method, comprising:
forming a first electrode routing over a semiconductor substrate;
forming a capacitor structure over the first electrode routing, the capacitor structure comprising a first metal plate serving to receive a first voltage potential and having opposite linear edges extending along a first direction, and a second metal plate over the first metal plate, the second metal plate serving to receive a second voltage potential different than the first voltage potential, the second metal plate having opposite linear edges extending along the first direction, wherein a first distance between the opposite linear edges of the first metal plate is different than a second distance between the opposite linear edges of the second metal plate, the first metal plate has a non-linear edge connecting the linear edges of the first metal plate, and the non-linear edge of the first metal plate has a plurality of notches arranged along a second direction perpendicular to the first direction; and
forming a second electrode routing over the capacitor structure, wherein the capacitor structure is connected between the first and second electrode routings.
