Description

technical field [0001] The invention relates to the technical field of plasma preparation, in particular to a controllable high-density plasma preparation device and a method for preparing a graphene film. Background technique [0002] The low-temperature plasma formed by low-pressure discharge is the main means of microelectronics processing, and it is used for deposition, etching, ash removal, polymerization or implantation, etc. One of the keys to the development of high-tech industries such as microelectronics, optoelectronics, and communications is the development of plasma microfabrication technology. [0003] The development process of low-pressure and low-temperature plasma sources for microfabrication has basically undergone three generations of updates: the first generation is a low-density single-chamber plasma source. The 13.56MHz radio frequency driven parallel plate electrode capacitively coupled discharge plasma etching machine used since the 1980s, plasma ge...
