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

Claim 18:
19. A method for fabricating a semiconductor device, comprising:
forming a plurality of gate-all-around (GAA) transistors over a front side of a substrate, wherein each of the GAA transistors includes a respective set of nanostructures, a respective gate structure wrapping around each of the set of nanostructures, and a respective pair of source/drain structures;
forming, over the front side, a first interconnecting structure electrically connected to the gate structures; and
forming, over a back side of the substrate opposite to the front side, a second interconnecting structure electrically connected to the pairs of source/drain structures;
wherein the plurality of GAA transistors, the first interconnecting structure, and the second interconnecting structure are collectively configured as a decoupling capacitor.
