Abstract: A damping support structure for preventing vibrations of an apparatus table supporting an apparatus for manufacturing ultra-high precision devices such as semiconductors and printed circuit boards. The apparatus table is supported by a support deck suspended to be horizontally displaceable. Linear motors are actuated in response to vibrations of the apparatus table detected by vibration sensors. The apparatus table is thus displaceable relative to a stationary section, to be safeguarded against the vibrations.
