Last updated:

Abstract:

A mechanism for localizing a substrate relative to a projection camera or other apparatus over large travel distances is described. The mechanism includes one or more trucks that move with the stage in a primary direction and remain stationary when the stage moves in an ancillary direction. The position of the trucks, together with relative distances between the truck(s) and a stage on which the substrate is supported facilitates alignment.
