  • What are the measuring methods of film thickness

    Generally, it can be divided into two types: in-situ measurement and off-site measurement. It is widely used in physical vapor deposition, such as microbalance, optical measurement and resistance measurement. The off-position measurement means that after the film is finished, the exercise of th...

  • What are the characteristics of good films? What are the influencing factors?

    It is said that under normal conditions, its application function will not fail. To achieve this, the film must generally have strong adhesion, low internal stress, little pinhole density, strong mechanical performance, uniform film thickness, and sufficient resistance to chemical erosion. The...
