Abstract:

The technical approach and status of development of synthetic single-crystal diamond (SCD) were introduced with the comparison of several different chemical vapor deposition (CVD) diamond techniques on their advantages and disadvantages.Coessential-joint growth technology, an effective method for breaking through the dimensional limitation and realizing the large size SCD, was focused on Microwave Plasma CVD (MPCVD). Inch sized SCD wafer was achieved. The discussion and analysis were presented on the scientific issues such as lateral growth, interface quality and evolution, as well as the control of 3D structure
connecting process. In addition, the prospects in the field of advanced applications were forecasted.
