초록

The lithography system installed inside precision industry's (e.g. TFT-LCD) production factories are increasing in size, thereby increasing its dynamic load along with it. Such condition causes vibration within the area where the system is installed, which then negatively affects the production line to produce defective products. To prevent this type of situation, the facilities should adopt dynamic design that considers the lithography system's dynamic load. This study predicts the maximum value allowed for dynamic stiffness (which is a ratio of vibration response against a single unit of the dynamic load) of the lithography system and explains the result of its application on actual structures inside the facilities.
