Pre-aligning a substrate in a lithographic apparatus, device manufacturing method, and device manufactured by the manufacturing method

摘要

A method of pre-aligning a substrate in a lithographic apparatus is described. The substrate has at least one alignment mark provided on a side of the substrate. The method includes determining a relationship between a position of the at least one alignment mark, at least part of an edge of the substrate, and a center of the substrate. A substrate support is provided to support a substrate, the substrate support having at least one optical view window at a predetermined location to view a part of the side of the substrate. The substrate is placed on the substrate support on the basis of the relationship to position the at least one alignment mark in the at least one optical view window.
