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 furnace lining rarely fails because the furnace reached an impossible temperature. It usually fails because the refractory material was selected for the wrong mix of heat, chemistry, load, and thermal cycling. The symptoms are familiar: spalling on the hot face, open joints, corroded anchors, and a shell that quietly consumes gas or electricity for months. Short answer: choose furnace refractory material by failure mode first, temperature second, and price third. Ceramic fiber and lightweigh...
