Abstract:
A demountable substrate frame (31), for use with a dockable substrate chuck having a substrate-frame-accepting operating surface, in a system for processing of a large-area microelectronics substrate by radiation projected by an optical subsystem in a small object field to scan a module within a multi-module active area of the substrate as the substrate moves, on an X-Y stage,characterized by: a planar body, having parallel substrate-accepting operating surface and supporting surface for supporting at least one substrate subject to being gripped by airflow through the dockable substrate chuck; airflow distribution means, at the substrate-accepting operating surface of said planar body, for providing a grip to a substrate by vacuum from dockable substrate chuck to said substrate-accepting operating surface; and means for providing repeatable position relationship with the dockable substrate chuck.
