    摘要: A precision positioning apparatus suitable for the positioning control system of a semiconductor exposing apparatus such as a stepper has, as its object, the provision of a non-contact type precision positioning apparatus capable of properly correcting the disturbance of posture or vibration based on low rigidityy which is a feature of a non-contact guide mechanism and accomplishing stable, highly accurate positioning at a high speed. The precision positioning apparatus is provided with a base plate, a movable member positioned on the base plate, a driving device for driving the movable member, a detecting device for detecting movement of the movable member, and a device for supplying the driving device with a signal regarding the movement of the movable member on the basis of a reference value and the output value from the detecting device. The supplying device includes a device for forming a correction signal for substantially negating a disturbance force to the movable member, by the use of the signal supplied to the driving device and the output from the detecting device. The signal supplied to the driving device can be corrected by the correction signal.

    摘要: A vibration control apparatus includes a first spring mechanism to support a first object as part of a first system. To control vibration of the first object, a first actuator applies a force to the first object via a command value generated by a first computing based on an output of a detection system. The detection system includes a second spring mechanism to support a second object as part of a second system. A third spring mechanism supports a third object as part of a third system. The first displacement detector detects displacement of the third object relative to the second object. The third object is prevented from being displaced relative to the second object. A second natural frequency of the second system is higher than a first natural frequency of the first system, and a third natural frequency of a third system is higher than the first natural frequency.

    摘要: The vibration isolation device of the present invention includes a first position feedback control system including a reference body system that is fixed to an object to be isolated from vibration and includes a reference body; a first driving unit that drives the object with respect to a base; and a first compensator that calculates a command value to the first driving unit based on position information obtained from the reference body system. Also, the reference body system includes a second position feedback control system including a second driving unit that drives the reference body with respect to the object; a first measuring unit that measures the position of the reference body relative to the object; and a second compensator that calculates a command value to the second driving unit based on position information obtained from the first measuring unit. Here, the second compensator is a PD compensator.
