Abstract: Methods and systems for epitaxial deposition using X-ray fluorescence (XRF) measurements and process control techniques are provided. The method involves performing an epitaxial deposition process to deposit alternating layers of silicon (Si) and silicon germanium (SiGe) on a substrate. XRF measurements determine the thickness and composition of these layers, allowing for precise control over layer thickness and composition. The process helps maintain the targeted strain and prevents defects, improving device performance. The XRF measurements can be performed in-situ or in a transfer chamber, enabling real-time adjustments to the deposition parameters. The method is applicable to various semiconductor devices, including 3D DRAM and gate-all-around (GAA) transistor devices.

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.
