Vapour Deposition Furnaces: The Core Equipment for the Development of the High-Tech Industry

In the modern high-tech industry, especially in the field of thin film deposition technology, chemical vapour deposition furnaces (CVD/PECVD) have become crucial equipment.

As an industry leader, Brother Furnace's CVD/PECVD equipment provides strong support for cutting-edge fields such as microelectronics, photovoltaics, flat panel displays, and energy storage, based on its outstanding performance and technological innovations.

Brother Furnace understands that these high-precision equipment must not only meet the stringent requirements for film quality, deposition rate and process consistency, but must also respond to increasing market demands and technological challenges.

Brother Furnace's CVD/PECVD tube furnace, with its advanced plasma technology, significantly improves the uniformity and stability of film deposition, providing customers with a reliable guarantee in their quest for higher performance, longer life and lower cost solutions.

In this article, Brother Furnace will discuss in depth the working principle and technical advantages of CVD/PECVD furnacce. Hope it can help you better understand the vapour phase deposition furnace.

Operating Principle of Chemical Vapor Deposition Furnaces

Thin film deposition systems grow thin films by converting gases into solid films in a high temperature or plasma environment and depositing them on the surface of a substrate. These processes can be divided into the following steps:

1. Introduction to Gases

Gases such as nitrogen, argon, etc., are introduced into the PECVD tube furnace by means of a precision mass flow meter. These gases react chemically under specific conditions to form thin film materials. Different combinations of gases can deposit different thin film materials, such as silicon film, silicon nitride, etc.

2. Heated Gases

In the CVD process, the gases are heated to a high temperature to decompose and deposit them on the substrate. In plasma vapour deposition equipment, the gas is excited by a radio frequency (RF) power supply to form a plasma. This plasma state effectively enhances the reaction rate and results in a more uniform film deposition.

3. Thin Film Deposition

The solid material generated by the decomposition of the excited gas is deposited on the surface of the substrate to form a uniform thin film. The deposition process is usually carried out in a vacuum environment to reduce gas contamination and improve the quality and purity of the film.

Brother Furnace offers different vacuum systems for customers to choose from. Effectively prevent the influence of gas impurities on film quality during the deposition process.

4. Temperature Control

In order to ensure the quality of the film, precise control of the gas flow and temperature is essential. Brother Furnace's gas deposition device is equipped with an intelligent 50-segment programmable automatic control system, which can be adjusted according to the specific process requirements. It is also capable of achieving temperature differences within one degree, ensuring process consistency and reliability.

Advantages of Brother Furnace's Vapour Deposition Furnaces

1. High Temperature Capability and Precise Control

Brother Furnace's CVD tube furnace has a maximum operating temperature of 1200°C. It is heated by HRE resistance wire, which ensures stability in high temperature environments.

The intelligent 50-segment programmable control system allows the user to customise the deposition process according to requirements and to control the temperature precisely (temperature control accuracy of ±1°C). This precise temperature control system ensures process consistency and reliability.

2. Safety Design

The CVD tube furnace is equipped with over-temperature protection and power leakage protection. When the temperature exceeds the set value, the over-temperature protection function will automatically cut off the power, preventing overheating-induced equipment damage or safety accidents.

The leakage protection function cuts off the power supply immediately when it detects the leakage phenomenon to protect the safety of operators. In addition, the furnace body adopts a double-layer air-cooled structure, the surface temperature is lower than 50℃, which reduces the impact of external heat radiation on the surrounding environment.

3. Highly Efficient Deposition Performance

The RF glow technology of the PECVD furnace dramatically increases the film deposition rate to a maximum of 10 A/S. This high uniformity ensures the consistency of the film on the substrate and reduces quality fluctuations in production. This design concept also results in less than 2% deviation between substrates, improving process consistency and stability.

4. Durability and Reliability

Brother Furnace insists on using high quality materials and processes for manufacturing to ensure the durability and long-term stability of the vapor deposition furnace.

The furnace chamber is made of high quality alumina polycrystalline fibre inorganic material formed by vacuum adsorption with Japanese technology, which has excellent heat preservation performance. The use of this material improves the thermal efficiency of the equipment, reduces energy consumption and extends the service life of the equipment.
