Abstract

The present invention discloses a microwave plasma chemical vapor deposition apparatus using a plasma antenna as a coupling antenna. The present invention also discloses a method for synthesizing diamond, which uses the plasma antenna as the coupling antenna to synthesize diamond by microwave plasma chemical vapor deposition. The application also discloses the application of a microwave plasma chemical vapor deposition apparatus in the synthesis of single crystal diamond. The microwave plasma chemical vapor deposition apparatus of the present invention is coupled by a plasma antenna, which cangreatly improve the efficiency of the antenna.

Description

technical field [0001] The present application relates to the technical field of single crystal diamond synthesis, in particular to a microwave plasma chemical vapor deposition device and a diamond synthesis method. Background technique [0002] Microwave plasma chemical vapor deposition (MPCVD) transmits the microwave generated by the microwave generator to the reactor with a waveguide, and feeds CH into the reactor 4 with H 2 The mixed gas, high-intensity microwave energy excites and decomposes the carbon-containing gas above the substrate to form active carbon-containing groups and atomic hydrogen, and forms a plasma, thereby depositing a diamond film on the substrate. [0003] The difference between different types of MPCVD devices lies in the different forms of plasma reaction chambers. From the form of vacuum deposition chamber, there are quartz tube type, quartz bell jar type and metal cavity type with microwave window. From the coupling mode of microwave and plasm...
