Abstract

A semiconductor device structure is provided. The semiconductor device structure includes a stack of semiconductor nanostructures over a base structure and a first epitaxial structure and a second epitaxial structure sandwiching the semiconductor nanostructures. The semiconductor device structure also includes a gate stack wrapped around each of the semiconductor nanostructures and a backside conductive contact connected to the second epitaxial structure. A first portion of the backside conductive contact is directly below the base structure, and a second portion of the backside conductive contact extends upwards to approach a bottom surface of the second epitaxial structure. The semiconductor device structure further includes an insulating spacer between a sidewall of the base structure and the backside conductive contact.
