Formation of dense diamond films

To grow the diamond films by using RF-MW mix-process, at first, diamond seeds were deposited on silicon substrate by RF plasma CVD, and then a diamond layer grown by MW plasma CVD on the seeds. The grain-size of diamond films deposited by using HF-MW mix-process was smaller and denser than those of the MW plasma CVD process. The deposited diamond films were analyzed by scanning electron microscophy, X-ray diffractometer and Raman spectroscopy.
