A Study of Vibration Characteristic for Semiconductor Chip Test Equipment

This paper aims to analyze the vibration characteristics of the test equipment that inspects any defects in manufactured semiconductor chips and classifies defective chips. This type of equipment should be robust against any vibrations because such vibrations can cause disruption in the process that requires higher precision. 3D model of the structure of the equipment has been used to configure vibration simulation model. Model analysis have been carried out to analyze which part of the equipment is weak against vibration. To minimize the vibration effect of the equipment, the thickness of the plate consist of the equipment and weights are modified. The results show that thicker plate and higher weight in the equipment can decrease vibration effect.
