摘要： Systems and approaches for silicon germanium thickness and composition determination using combined XPS and XRF technologies are described. In an example, a method for characterizing a silicon germanium film includes generating an X-ray beam. A sample is positioned in a pathway of said X-ray beam. An X-ray photoelectron spectroscopy (XPS) signal generated by bombarding said sample with said X-ray beam is collected. An X-ray fluorescence (XRF) signal generated by bombarding said sample with said X-ray beam is also collected. Thickness or composition, or both, of the silicon germanium film is determined from the XRF signal or the XPS signal, or both.

In one embodiment, the method provides depositing a material on a substrate within a vapor deposition chamber coupled to a buffer chamber contained within a mainframe while maintaining a pressure of about 1×10−6 Torr or lower within a transfer chamber contained within the mainframe. The method further includes transferring the substrate from the vapor deposition chamber to the buffer chamber by a substrate handling robot while flowing a gas into the buffer chamber, evacuating the vapor deposition chamber, and maintaining a greater internal pressure within the buffer chamber than in the vapor deposition chamber. In some embodiments, the method includes transferring the substrate from the transfer chamber to a PVD chamber coupled to the transfer chamber by another substrate handling robot and depositing another material on the substrate within the PVD chamber.
