Semiconductor wafers and flat panel display (FPD) substrates can be attached firmly to a vacuum chuck mechanism without being scratched during transport or during instantaneous high-speed rotation using a spin coater, etc.
Demand is gradually increasing for rotary feedthroughs for use in vacuum chucks because they offer the advantage of allowing the vacuum system to be routed through them, thereby eliminating unnecessary space and complexity. In addition, they provide very stable high speed rotation.
We recommend Function Enhanced Products - Gas Induction Type for this application.
