Industries involved

TFT-LCD

The process special gases used in the CVD deposition process of TFT-LCD manufacturing process are silane (S1H4), ammonia (NH3), phosphine (PH3), nitrous oxide (N2O), NF3, etc. In addition, high purity hydrogen and high purity nitrogen and other bulk gases are also involved in the process. Argon is used in the sputtering process, and the sputtered film forming gas is the main material for sputtering. First, it is required that the film-forming gas cannot react with the target, and the most appropriate gas is inert gas. A large amount of special gas will also be used in the etching process, while the electronic special gas is mostly flammable, explosive and highly toxic, so the requirements for gas circuit and technology are very high. Wofei Technology specializes in the design and installation of ultra-high purity special gas transmission system.

Special gases are mainly used in film forming and dry etching processes in LCD industry. There are many kinds of LCD, among which TFT-LCD is the most widely used LCD technology due to its fast response time, high imaging quality and gradually lower cost. The manufacturing process of TFT-LCD panel can be divided into three stages: front array, middle cell and rear module assembly. The electronic special gas is mainly used in the film forming and dry etching stages of the front array process. After multiple film forming processes, SiNx non-metallic films and metal films such as grid, source, drain and ITO are respectively deposited on the substrate.
