PECVD rotary tube furnace_Zhengzhou Kejia Furnace

Product Introduction:

The PECVD rotary tube furnace system is suitable for surface film deposition of powder materials. The system consists of a high-power RF power supply (500W, 13.56MHz), a vacuum system, and a rotary tube furnace. Utilize plasma characteristics to control or influence gas phase reactions and chemical reaction processes on material surfaces, and deposit thin films at appropriate temperatures. PECVD deposited thin films have good electrical properties, good substrate adhesion, and good step coverage, which make them widely used in fields such as large-scale integrated circuits, optoelectronic devices, MEMS, and so on. It belongs to a type of pecvd systems.

Main product advantages:

1. PECVD has the advantages of low basic temperature, fast deposition rate, good film quality, fewer pinholes, and less cracking;
2. In the PECVD process, due to the impact of high-speed electrons in the plasma on neutral reaction gas molecules, neutral reaction gas molecules will become fragments or be in an activated state, which is prone to reactions;
3. By utilizing radio frequency and other means, gases containing atoms composed of thin films can form a plasma locally, which has strong chemical activity and is prone to reactions, resulting in the deposition of the desired thin film on the substrate;
4. The vacuum system consists of a rotary vane vacuum and a digital vacuum gauge, with a cold limit vacuum degree of up to 10Pa;
5. Adopting quick connect flange sealing, easy and fast loading and unloading;
6. The heating area adopts a single temperature zone with a heating zone of 200mm, which is easy to operate, reliable in sealing, and has high comprehensive performance indicators.
7. The furnace tube adopts customized variable diameter furnace tube, with a quartz feeding table inside the tube wall, allowing the material to be heated more fully. The furnace tube rotates at 360 ℃ and the rotation speed is adjustable.
8. The temperature control system adopts PID intelligent program for temperature control, and can set multiple temperature rise and fall programs.
9. The flange is equipped with an inlet and outlet cyclone adapter, which can introduce inert protective gases such as nitrogen and argon, and can be used in atmospheric environments.
10. Safety protection, with over temperature protection function. When the temperature exceeds the allowable setting value, the automatic alarm protection function ensures safe and reliable operation.
13. Our company has the ability to independently develop, design, produce, and process our machines. We provide lifelong parts replacement and upgrade services.
