APPARATUS FOR CARRYING CROSS-LINES |
摘要 |
Precisely adjustable transporter for moving a reticle past an optical slit as a step in the production of semiconductor wafers. The reticle stage rides along a pair of optically flat planar, intersecting, bearing surfaces supported by air bearings on each bearing surface. Pressurized air and vacuum may be simultaneously employed to effect substantially friction-free motion while preventing displacement from the bearing surfaces. Axial adjustments on each air bearing permit precise adjustment of the reticle stage and reticle. |
