Abstract
Integrated circuit structures having backside self-aligned penetrating conductive source or drain contacts, and methods of fabricating integrated circuit structures having backside self-aligned penetrating conductive source or drain contacts, are described. For example, an integrated circuit structure includes a sub-fin structure over a vertical stack of horizontal nanowires. An epitaxial source or drain structure is laterally adjacent and coupled to the vertical stack of horizontal nanowires. A conductive source or drain contact is laterally adjacent to the sub-fin structure and extends into the epitaxial source or drain structure. The conductive source or drain contact does not extend around the epitaxial source or drain structure.
