PECVD plasma enhanced chemical vapor deposition equipment is mainly used for the growth of silicon nitride and silicon oxide thin films in a clean vacuum environment; it uses single-frequency or dual-frequency plasma enhanced chemical vapor deposition technology and is an ideal choice for depositing high-quality silicon nitride and silicon oxide films. The equipment takes advantage of low temperature and low energy consumption, generates high-density plasma in the reaction chamber, effectively excites gas molecules, promotes chemical reactions, and deposits uniform, dense, and well-adhesive thin films on the substrate surface. The PECVD process can not only achieve precise film thickness control, but also improve the interface quality and overall structural stability of the film layer. Therefore, it is widely used in the manufacture of integrated circuits, flat panel displays, solar cells, and other microelectronic devices. In addition, the equipment is usually equipped with an automated control system to achieve precise control of key parameters such as temperature, pressure, and gas flow, thereby improving production efficiency and product consistency, and meeting the high standards for film quality under different process requirements.
