Investigation of electrostatic bonding time model with point cathode

This paper discusses a novel method of modeling and simulation of anodic bonding technique, which is widely used in fabrication of MEMS device and micro system. The emphasis are the bond expansion model and extended time formula of silicon-glass anodic bonding, and based on which, visual simulation of the process is achieved. In practical experiments, by utilizing the math model, simulation result matches well with the real process, perfectly displaying the electricity characteristics. This novel approach of simulation possesses high practicality, and additionally, will be important and valuable in the development of MEMS technology and microelectronics.
