1. Equipment principle
The radio frequency PECVD coating electric furnace uses radio frequency power to excite gas and generate plasma, causing gaseous substances containing thin films to undergo chemical reactions under the action of the plasma, thereby depositing the desired thin film on the surface of the sample. Radio frequency electric fields usually use inductive coupling or capacitive coupling methods to achieve low-temperature deposition in low-voltage chemical vapor deposition processes by utilizing glow discharge plasma to influence the process.

2. Core advantages
Low temperature deposition: suitable for temperature sensitive substrate materials, such as flexible substrates or organic materials.
High deposition rate: Plasma enhanced technology can greatly improve the growth rate of thin films.
High film quality: The deposited film has good uniformity, high density, and strong adhesion.
Process flexibility: The composition and properties of the film can be precisely controlled by adjusting parameters such as gas composition, power, and temperature.

3. Application Fields
Radio frequency PECVD coating electric furnace has a wide range of applications in multiple fields:
Semiconductor industry: used for manufacturing dielectric layers, low-k dielectric materials, and silicon-based optoelectronic devices in integrated circuits.
Photovoltaic field: It is the main deposition technology for manufacturing solar cells and photovoltaic modules, which can improve the photoelectric conversion efficiency of solar cells.
In the field of optics, thin films with various optical functions such as absorption, transmission, reflection, refraction, and polarization can be prepared.
Automotive electronics: providing reliable protection for key components such as battery management systems, onboard sensors, and headlight lenses.
Medical field: Used for surface modification of medical implants, such as artificial joints, dental implants, etc., to improve the service life of implants and patient comfort.
Mechanical components: Deposition of wear-resistant coatings such as diamond-like carbon (DLC) to improve the material's wear resistance and low friction.

4. Equipment structure
The RF PECVD coating electric furnace mainly consists of the following parts:
Vacuum and pressure control system: Maintain a vacuum environment in the reaction chamber and control gas pressure.
Deposition system: including RF power supply, electrodes, reaction chamber, etc., used for generating plasma and depositing thin films.
Gas and flow control: Accurately control the type and flow rate of the reaction gas.
System security protection system: Ensure the safe operation of equipment and prevent accidents from occurring.
Computer control: Achieving automated control of equipment and precise adjustment of process parameters.

5. Process parameters
The process parameters of RF PECVD coating electric furnace have a significant impact on the quality and performance of thin films, mainly including:
RF power: The higher the RF power, the greater the ion bombardment energy, which is beneficial for improving the quality of the deposited film. However, excessive power may also cause damage to the substrate.
Gas pressure: If the gas pressure is too high, the reaction gas in the unit increases, the deposition rate increases, but the average free path decreases, which is not conducive to the coverage of the deposition film on the steps. If the air pressure is too low, it will affect the deposition mechanism of the film, leading to a decrease in the density of the film.
Substrate temperature: The influence of substrate temperature on the quality of thin films mainly lies in the local density of states, electron mobility, and optical properties of the film. The increase in substrate temperature is beneficial for compensating for the dangling bonds on the surface of the film, resulting in a decrease in defect density of the film.
Electrode spacing and reaction chamber size: The selection of electrode spacing should consider the starting voltage and electric field edge effect, while the reaction chamber size affects productivity and thickness uniformity.

6. Common problems and solutions
Poor cleanliness of sample surface: Check if the sample surface is clean and clean it if necessary.
Poor cleanliness of process chamber: Clean the process chamber to remove residues and pollutants.
Abnormal sample temperature: Check if the temperature control system is functioning properly and calibrate the temperature measuring thermocouple.
Abnormal pressure during membrane deposition: Check the leakage rate of the chamber vacuum system to ensure a stable vacuum environment.
Unreasonable RF power setting: Check the RF power supply and adjust the set power to the appropriate range.
