Abstract

A stacked field effect transistor (stacked-FET) device includes a first layer comprising at least one first layer transistor structure comprising a plurality of first layer terminals, a diffusion break dielectric fill region adjacent to one of the first layer terminals, a second layer overlying and adjacent to the first layer and comprising at least one second layer transistor structure comprising a plurality of second layer terminals, and a contact wiring between the first layer and the second layer passing through the diffusion break dielectric fill region of the first layer and connecting with one of the second layer terminals.
