Zusammenfassung:A semiconductor device is provided. The semiconductor device includes a bottom field effect transistor (FET) including a bottom source-drain epitaxial layer formed on sides of the bottom FET; a top FET stacked over the bottom FET; a back-end-of-line (BEOL) layer formed on the top FET; a bottom gate contact formed in contact with the bottom FET and having an extending portion of the bottom gate contact that extends laterally over the bottom source-drain epitaxial layer; and a top gate contact formed in contact with the extending portion of the bottom gate contact and electrically connecting the bottom gate contact to the BEOL layer.
