PECVD Tube Furnace
The PECVD tube furnace is a plasma gas phase deposition tube furnace system, which consists of a quartz reaction chamber, a radio frequency power supply, a multi-channel gas mixing system, a vacuum unit, and a reaction control system. The furnace uses high-purity alumina fiber material, and the surface is coated with imported high-temperature alumina coating to extend the service life of the instrument and improve heating efficiency. A radio frequency induction device is installed in front of the traditional chemical vapor deposition to ionize the reaction gas and generate plasma. The high activity of the plasma accelerates the reaction. It has good uniformity and repeatability, can form films over a large area, can form films at low temperatures, has excellent step coverage, and is easy to control the composition and thickness of the film and easy to industrialize. It is widely used in the growth of thin films such as graphene, silicon monoxide, silicon nitride, silicon oxynitride, and amorphous silicon (A-SI: H).

A vacuum furnace is a high-tech industrial oven used for heat treatment processes, primarily in the manufacturing and processing of metals, ceramics, and other materials. The furnace operates in a controlled vacuum environment, meaning that the air is removed from the chamber, creating a low-pressure atmosphere. This unique condition allows for specific and often superior material properties to be achieved during the heating process. Let’s dive deeper into the purpose of a vacuum furnace and why...
