Stage assembly having a follower assembly
First Claim
1. A stage assembly that moves a device along a Y axis, the stage assembly comprising:
- a device stage that retains the device;
a stage mover assembly connected to the device stage, the stage mover assembly moving the device stage along the Y axis, the stage mover assembly generating a reaction force that is transferred to a reaction component; and
a first follower frame that constrains motion of the device stage along a Z axis that is orthogonal to the Y axis, the first follower frame being moved substantially concurrently with and to substantially follow the movement of the device stage along the Y axis;
wherein the reaction component is not directly connected to the first follower frame.

Abstract
A stage assembly (10) for moving and positioning a device (26) includes a device stage (14), a stage mover assembly (16), and a follower assembly (18). The stage mover assembly (16) moves the device stage (14) along an X axis, along a Y axis and about a Z axis. The follower assembly (18) includes a first follower guide (76) and a first follower frame (80). The first follower guide (76) supports the first follower frame (80) and allows the first follower frame (80) to move along the Y axis. Further, the first follower frame (80) supports the device stage (14) and allows the device stage (14) to move along the Y axis, along the X axis, and about the Z axis. Importantly, the first follower frame (80) is moved along the Y axis with a first follower mover (84). With this design, the device stage (14) can be made relatively thin vertically and the control lines (20) to the device stage (14) can be relatively short.
