Stage assembly including a reaction assembly having a connector assembly
First Claim
1. A stage assembly that moves a device relative to a mounting area, the stage assembly comprising:
- a stage that retains the device;
a stage mover assembly connected to the stage, the stage mover assembly moving the stage along a first axis and generating reaction forces; and
a reaction assembly coupled to the stage mover assembly, the reaction assembly including a first reaction subassembly having a first mass that is movable along the first axis, a second reaction subassembly having a second mass that is movable along the first axis, and a connector assembly that connects the reaction subassemblies together, allows for relative movement of the masses with at least one degree of freedom and inhibits relative movement of the masses with at least one degree of freedom.

Abstract
A stage assembly (220) for moving and positioning a device (200) includes a stage base (202), a stage (206), a stage mover assembly (204), and a reaction assembly (226). The stage mover assembly (204) moves the stage (206) relative to the stage base (202). The reaction assembly (226) is coupled to the stage mover assembly (204). The reaction assembly (226) reduces the reaction forces created by the stage mover assembly (204) that are transferred to the stage base (202). In one embodiment, the reaction assembly (226) includes a pair of masses (250A), (250B) and a connector assembly (236) that connects the masses (250A), (250B) together, allows the masses to move independently along a first axis, and causes the masses (250A), (250B) to move concurrently along a second axis.
