A method for forming a photodetector device includes forming waveguide feature on a substrate, and forming a photodetector feature including a germanium (Ge) film, the Ge film deposited on the waveguide feature using a plasma enhanced chemical vapor deposition (PECVD) process, the PECVD process having a deposition temperature from about 500° C. to about 550° C., and a deposition pressure from about 666.612 Pa to about 1066.579 Pa.
