Abstract:
1. An alignment method of micro-alignment members, comprising: a step for preparing a slide base reciprocatably held to a guide member, a holder mounting member mounted on the slide base, a first microscope disposed on one side of the guide member, the first microscope having an optical axis orthogonal to a longitudinal direction of the guide member, a first micro-alignment member disposed on the one side of the guide member spaced from the first microscope in the longitudinal direction of the guide member, and a second microscope disposed on the other side of the guide member to face to the first micro-alignment member across the guide member, the second microscope having an optical axis orthogonal to the longitudinal direction of the guide member; a first step for mounting a reticle on the holder mounting member, for moving the slide base along the guide member such that the reticle faces to the first microscope, and for moving and adjusting the holder mounting member in a direction orthogonal to each of the optical axis of the first microscope and a moving direction of the slide base and in the moving direction of the slide base, such that a center of the reticle aligns with the optical axis of the first microscope; a second step for moving the slide base along the guide member such that the reticle faces to the second microscope, and for moving and adjusting the second microscope in a direction orthogonal to each of the optical axis of the second microscope and the moving direction of the slide base and in the moving direction of the slide base, such that the center of the reticle aligns with the optical axis of the second microscope; a third step for moving and adjusting the first micro-alignment member in a direction orthogonal to each of the optical axis of the second microscope and the moving direction of the slide base and in the moving direction of the slide base, such that a center of the first micro-alignment member aligns with the optical axis of the second microscope; and a fourth step for mounting a second micro-alignment member on the holder mounting member instead of the reticle, for moving the slide base along the guide member such that the second micro-alignment member faces to the first microscope, and for moving and adjusting the holder mounting member in the direction orthogonal to each of the optical axis direction of the first microscope and the moving direction of the slide base and in the moving direction of the slide base, such that the center of the second micro-alignment member aligns with the optical axis of the first microscope, and a fifth step for moving the slide base along the guide member from a position that the center of the second micro-alignment member aligns with the optical axis of the first microscope to a position that the center of the second micro-alignment member aligns with the optical axis of the second microscope, such that the second micro-alignment member faces to the second microscope.
