Abstract
The present invention discloses an integration flow of germanium into a conventional CMOS process, with improvements in performing selective area growth, and implementing electrical contacts to the germanium, in a way that has minimal impact on the preexisting transistor devices. The present invention also provides methods to integrate the germanium without impacting the optical or electrical performance of these devices, except where intended, such as in a germanium photodetector, or germanium waveguide photodetector.
