Abstract
Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, integrated circuit structures having source or drain structures with a relatively high germanium content are described. In an example, an integrated circuit structure includes a fin including a semiconductor material. A gate stack is over an upper fin portion of the fin. A first epitaxial source or drain structure is embedded in the fin at a first side of the gate stack. A second epitaxial source or drain structure is embedded in the fin at a second side of the gate stack. The first and second epitaxial source or drain structures include silicon and germanium and have a same or greater atomic concentration of germanium than the fin.
