MPCVD stands for Microwave Plasma Chemical Vapor Deposition. It is a method of growing high quality diamond films in laboratory by using a carbon-containing gas and a microwave plasma.
MPCVD System
The MPCVD (Microwave Plasma Chemical Vapor Deposition) system is a process used to deposit thin films onto a substrate surface. The system consists of a vacuum chamber where the deposition process takes place, a microwave generator, and a gas delivery system. The microwave generator is used to generate a plasma inside the vacuum chamber, which is used to decompose and deposit the gas species onto the substrate.
The microwave generator is typically a magnetron or klystron, which generates microwaves in the range of 2.45 GHz. The microwaves are coupled to the vacuum chamber through a quartz window.
The gas delivery system consists of mass flow controllers (MFCs) that control the flow of gas into the vacuum chamber. The MFCs are calibrated in standard cubic centimeter per minute (sccm).
The substrate temperature is controlled by the position of the plasma and is measured by a thermocouple. The plasma is used to heat the substrate, and the temperature is monitored by the thermocouple to ensure that the substrate is at the desired temperature during the deposition process.
Applications
MPCVD is a promising technology for producing low-cost, high-quality large diamonds.
Diamond's unique properties, including its hardness, stiffness, high thermal conductivity, low thermal expansion, radiation-hardness, and chemical inertness, make it a valuable material.
Despite its great potential, the high cost, limited size, and difficulty controlling impurities of natural and synthetic high-pressure, high-temperature diamonds have limited their applications.
MPCVD is the primary equipment used for growing diamond gemstones and films.
Diamond film growth can be either monocrystal or poly-crystalline, and it is extensively used in the semi-conductor industry for large-size diamond substrates as well as in the diamond cutting or drilling tools industry.
Compared to the HPHT method for lab-grown diamonds, the microwave CVD method is advantageous for large-sized diamond growth at a lower cost, making it an ideal solution for applications of semi-conductor diamonds, optics diamond growth, and the large jewelry diamond market needs.
Advantages of MPCVD
MPCVD is a diamond synthesis method that has several advantages over other methods, such as HFCVD and DC-PJ CVD. It avoids diamond contamination by hot wires and allows the use of multiple gases to meet different industrial needs. Compared to DC-PJ CVD, it enables smooth and continuous adjustment of microwave power and stable control of the reaction temperature, which avoids crystal seeds falling off the substrate due to arcing and flame failure. With a large area of stable discharge plasma, the MPCVD method is considered the most promising diamond synthesis method for industrial applications.
The diamonds produced through MPCVD are of higher purity compared to those produced using the HPHT method, and the production process consumes less energy. Additionally, the MPCVD method facilitates the production of larger diamonds.

Working Processing
The MPCVD machine controls the flow of each gas path and cavity pressure while introducing reactant gases (such as CH4, H2, Ar, O2, N2, etc.) into the cavity under specific pressure. After stabilizing the airflow, the 6KW solid-state microwave generator generates microwaves that are then introduced into the cavity through the waveguide.
The reaction gas transforms into a plasma state under the microwave field, forming a plasma ball that hovers above the diamond substrate. The high temperature of the plasma heats the substrate to a specific temperature. Excess heat produced in the cavity is dissipated by the water cooling unit.
To ensure optimal growth conditions during the MPCVD single crystal diamond growth process, we adjust factors such as power, gas source composition, and cavity pressure. Furthermore, since the plasma ball doesn't contact the cavity wall, the diamond growth process is free from impurities, thereby enhancing the diamond's quality.

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
