The system adopts an excellent microwave transmission system consisting of a high-performance microwave circulator, a three pin mixer, a water load with reflected wave sampling, and a connected waveguide segment waveguide. It ensures good isolation of the reflected wave from the magnetron, ensuring its stable operation. It can also conveniently adjust the optimal match when the plasma load changes, achieving the optimal transmission of microwave power. Through sampling of the reflected wave, the reflected power and real-time working status are displayed digitally.

2.3. Mode Transformation and Downinjection Microwave Coupling Cavity

This is a new generation of relatively mature microwave plasma coupling cavities, which are composed of cylindrical cavities operating in TM mode, gate button coaxial waveguide couplers with adjustable coaxial coupling probes, and plate quartz windows. By adjusting the waveguide short-circuit piston and coaxial coupling probe, microwave power can be efficiently coupled to the plasma discharge cavity over a wide operating range, generating high-density, high ionization degree, and large area uniform and stable microwave discharge. It adopts a double-layer water-cooled cavity wall to ensure stable operation.

2.4. Multi port plasma discharge cavity

This system adopts a large volume discharge chamber with a double-layer water-cooled structure welded from stainless steel, and the upper end is connected to the microwave reaction chamber, which is the continuation part of the cylindrical cavity. It also has the following functional ports:

1) A rotating door type feeding and discharging window is set up in front of the cavity, which can facilitate the discharge of substrate samples of no less than 50mm, and is equipped with a mesh microwave shielding window to clearly observe the discharge operation in the cavity during operation. Infrared temperature measurement is used for substrate temperature measurement at 300-1400 ºC

2) A specially designed inflation flange is used to provide the main mixing and inflation pipelines, as well as the inflation ring near the substrate, as an auxiliary inflation pipeline to form a double-layer gas feeding system.

The above design makes the water-cooled discharge chamber of this port have a large volume and complete functions, especially suitable for the needs of small-scale plasma processing.

2.5. Sample holder adjustment

This device can electrically continuously adjust the cavity plate and sample substrate stage respectively to achieve the optimal state of the plasma discharge area, which is simple, reliable, and easy to control. It can meet the requirements of various plasma processing processes.

2.6. Vacuum acquisition and measurement

The system uses a vacuum pump with a pumping speed of 8L/s as the pumping system, with an ultimate vacuum better than 6x10-1Pa. The system is equipped with medium to low pressure measurement gauges from the atmosphere to 10-1Pa and pressure resistance vacuum gauges from 100Pa to 100kPa. The measuring instruments are placed in the cabinet for easy control and reading.

Static sealing adopts silicone rubber and metal sealing; The dynamic seal adopts a metal corrugated pipe structure. The working pressure control is completed using high-precision valves and controllers, with stable air pressure control and convenient adjustment.

2.7. Multi channel gas mass flow control (MFC)

To ensure the process requirements of MPCVD, the system adopts a 4-way gas mass flow control system supply and control system (MFC) composed of H2 (1SLM), CH4 (100SCCM), O2 (50SCCM), and N2 (50SCCM). The system adopts a reliable 1/4 'VCR interface built-in in the equipment cabinet, which is short, compact, and easy to control and adjust.

2.8. The control system and cabinet
System adopt a compact and concise main structure, as well as independent control units. Adopting PLC and touch screen multi parameter control, the entire equipment has a beautiful appearance and easy and reliable operation. The main control cabinet is equipped with automatic protection for overcurrent, overheating, water interruption, as well as power and fault indications.Microwave leakage is superior to national standards.
