초록

In the case of a sensitive equipment, it require a vibration free environment to provide its proper function. Especially, lithography and inspection device, which have sub-nanometer class high accuracy and resolution, have come to necessity for producing more improved Giga Class semi conductor wafers. The aim of this study is to evaluate the allowable vibration response of a precision inspect ion equipment, which has some trouble in field, by using experimental measurement data and to proposal a proper ant i-vibration method.
