METHOD FOR PRODUCING A MARKER ON A SUBSTRATE, LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD
摘要:
A method of producing a marker on a substrate includes projecting a patterned beam on a layer of resist disposed on a substrate in a lithographic apparatus to create a latent marker; and locally heating the substrate at the marker location in the lithographic apparatus to transform the latent marker into a detectable marker.
