Description

The main components of KOH developer, KOH, surfactant and metal protective agent, can dissolve the uncured part of the photoresist and develop the part exposed to ultraviolet light, with faster development speed and higher selectivity. The optimal pH value for development is between 12-13. In addition, the developer also contains some auxiliary agents such as surfactants and antioxidants, which can also improve the performance of the developer and improve the development effect and stability. However, potassium hydroxide series developers contain mobile ion contamination (MIC), which is not suitable for high-performance display panels and integrated circuit industries that are very sensitive to pollution.
