The activation energy required for chemical vapor deposition reactions is usually derived from heat, plasma, and lasers.

①Thermal Activation Method
Chemical vapor deposition in the thermal energy activation method requires a certain amount of thermal energy, that is, the reaction environment needs to reach a certain temperature, and the temperature required is usually related to the pressure of the reaction gas, the smaller the pressure, the higher the temperature required.
Thermal CVD can be performed at different pressure levels from atmospheric pressure to high vacuum. However, a certain amount of energy is required to activate the reaction, and the reaction can take different forms. During heat treatment, the temperature applied to the substrate provides the energy used to facilitate the chemical reaction and the diffusion of the substance to the surface.

Chemical vapor deposition can be divided into atmospheric pressure chemical vapor deposition (APCVD) and low pressure chemical vapor deposition (LPCVD) according to the reaction gas pressure.
②Plasma activation mode
Chemical vapor deposition using plasma as an activation method is called plasma-enhanced chemical vapor deposition (PECVD). This has the advantage of low-temperature treatment compared to heat treatment methods such as low-pressure chemical vapor deposition (LPCVD). The PECVD treatment temperature range is between 200-400°C. The LPCVD process temperature range is between 425-900°C.

This type of PECVD is widely used in the semiconductor industry to deposit silicon nitride (Si3N4) and phosphosilicate glass (PSG) with a thickness of a few microns and a deposition rate of 5-100nm/min.
③Laser Activation Method
Chemical vapor deposition using a laser as an activation method is called laser-enhanced chemical vapor deposition. With the development of high technology, the use of laser enhanced chemical vapor deposition is also a commonly used method.
