Abstract:
PROBLEM TO BE SOLVED: To provide a substrate clamp system and a lithographic device capable of avoiding stress guided by particles and/or heat in a substrate and improving pattern transfer accuracy.SOLUTION: A lithographic device configured so as to transfer a pattern from a patterning device to a substrate W includes: a substrate table configured so as to hold the substrate; a first clamp system 40, 128 configured so as to clamp the substrate table to a substrate table support structure; and a second clamp system 40, 129 configured so as to clamp the substrate to the substrate table after the substrate table is clamped to the substrate table support structure.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus that can avoid stress guided by particles and heat in a substrate and can improve precision of pattern transcription. SOLUTION: This lithographic apparatus comprises a support structure MT connected with a primary positioner PM, which is configured to support a lighting system (illuminator) IL configured to adjust radiation beam B and a patterning device MA, and also to correctly position the patterning device according to a specific parameter; a substrate table WT that can connect with a secondary positioner PW, which is configured to correctly position the substrate W according to a specific parameter; and a projection system PS that is configured to project a pattern given to the radiation beam B by the patterning device MA to the target portion C of the substrate W.
