The gap isolates the wafer or reticle from the flat, polished surface of the base, but is dimensioned to inhibit migration of particles into the gap, thereby preventing contamination of sensitive surfaces of the wafer or reticle. Diffusion filters provide pressure equalization without filter media. Moveable reticle pins on the top cover provide reticle restraint. Dual containment pod embodiment provides further isolation and protection. | 12-10-2009 |
