본문내용

Recently, high accuracy and high precision are required in various industrial fields that are composed of semiconductor manufacturing apparatus and ultra precision positioning apparatus and information system and so on. The positioning technology is a very important one among them.
This technology has been rapidly developed, its field needs for positioning accuracy to high as submicron. It is expected that accuracy with 10 ㎚ in precision working and accuracy with 1 ㎚ in ultra precision working are reached at the beginning of 2000s. Also, high speed and low vibration are really needed for the same reason.
