SAMPLE STAGE APPARATUS AND METHOD OF CONTROLLING THE SAME |
摘要 |
The present invention provides a stage apparatus capable of reducing a positioning time without increasing a positional deviation. A positioning control method of a sample stage apparatus includes: a high-speed movement step of moving a table to a high-speed movement target position at a first movement speed; a positional deviation correcting step of moving the table to a low-speed positioning step start position at a second movement speed that is lower than the first movement speed; a low-speed positioning step of moving the table to a target position at a third movement speed that is lower than the second movement speed. After the low-speed positioning step is completed, a rod connected to a motor returns to its original position to separate a pin of the rod side from a concave portion of the table side.
