A Dynamic Structure Design of PC type Sub-structure for next Semi-conduct, TFT-LCD Fab based on Dynamic Test and Simulation

차세대 반도체, TFT-LCD Fab 구조설계를 위한 PC형 격자보에 대한 동적 특성 평가 및 개선방안

In design stage of high precision manufacture/inspection FAB building, it is necessary to investigate the vibration allowable limits of high precision equipment and to study a structure dynamic characteristics of C/R and Sub-structure in order to provide a structure vibration environment to satisfy thess allowable limits. The aim of this study is to investigate the dynamic characteristics of PC-Type mock-up structures designed for next TFT LCD FAB through vibration measurement and analysis procedure, therefore, to provide a proper dynamic structure design for high precision manufacture/inspection work process, which satisfy thess allowable limits.
