Abstract:
A method for exposing a pattern onto a substrate using stepping and scanning in a system including a base, the method comprising steps of:disposing a fixed guide member having a first direction guide surface extended in said first direction on said base;slidably coupling a movable guide member having a second direction guide surface extended in a second direction perpendicular to said first direction to said fixed guide member at one end portion, said movable guide member being movable in said first direction;supporting said substrate on a movable stage assembly, said movable stage assembly being supported on said base and operatively coupled to said movable guide member for movement in said first direction;controlling movement of said movable stage assembly in said second direction by said second direction guide surface of said movable guide member;moving said movable guide member and said movable stage assembly in said first direction as a cross scan movement of said substrate in stepping and scanning; andmoving said movable stage assembly in said second direction relative to said movable guide member as a scan movement of said substrate in stepping and scanning.
