Abstract: Embodiments of the present disclosure relate to the field of electronic device manufacturing, and in particular, to multi-layered epitaxial stacks, such as complementary field-effect-transistors (cFETs). A method is used to fabricate a layered middle dielectric isolation (MDI) structure and carbon-doping of epitaxially grown silicon germanium layers together in the cFETs. In some embodiments, by integrating the layered MDI structure together with carbon-doping of SiGe layers into the cFETs, relaxation, wafer bow, and defects in a stack have been significantly reduced when compared to traditional stacks. Advantageously, multi-layered epitaxial stacks incorporate a greater number of silicon channels (e.g., pMOS and nMOS channels) when compared to traditional stacks. Furthermore, the selectivity in the downstream processes is improved by an order of magnitude.
