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

Claim 0:
1. A circuit structure, comprising:
a substrate;
a first transistor stack over the substrate, the first transistor stack comprising:
a first transistor, over the substrate, wherein the first transistor is a first conductivity type; and
a second transistor, above the first transistor, wherein the second transistor is a second conductivity type different from the first conductivity type; and

a plurality of first conductive lines in a first metal layer above the first transistor stack, the plurality of first conductive lines comprising, over the first transistor stack:
a power conductive line configured to route power to the first transistor stack;
one or more signal conductive lines configured to route signals to the first transistor stack; and
a shielding conductive line configured to shield the routed signals on the one or more signal conductive lines, wherein the one or more signal conductive lines are between the power conductive line and the shielding conductive line.
