Substrate carrier and method for making a substrate carrier
First Claim
Patent Images
1. A carrier constructed to carry a lithographic substrate or a lithographic patterning device, said carrier comprising:
- a first member provided with an open hollow structure that is open to at least one side of said first member, said first member constructed to support a lithographic substrate or a lithographic patterning device; and
a second member connected to said first member, such that a closed hollow internal structure is formed between said first and second members.

Abstract
A carrier for carrying a lithographic substrate or a lithographic patterning means. The carrier comprises a first member provided with an open hollow structure that is open to at least one side of the member. The carrier further comprises a second member connected to the first member, such that a closed hollow internal structure is formed between the carrier members.

8. A lithographic apparatus comprising:
-
a radiation system constructed to provide a beam of radiation; a support structure constructed to support a patterning device, said patterning device serving to impart a cross-section of said beam with a pattern to form a patterned beam; and a projection system that projects said patterned beam onto a target portion of a substrate, wherein said apparatus further includes a table constructed to hold said substrate or said patterning device, said table including a carrier constructed to carry a lithographic substrate or a lithographic patterning device, said carrier including a first member provided with an open hollow structure that is open to at least one side of said first member, said first member constructed to support a lithographic substrate or a lithographic patterning device; and a second member connected to said first member, such that a closed hollow internal structure is formed between said first and second members. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for making a carrier for carrying a lithographic substrate or a lithographic patterning device, the method comprising:
-
providing at least two members, one of the at least two members being constructed to support a lithographic substrate or a lithographic patterning device; and connecting the at least two members to each other to form a carrier, where the at least two members are formed in such a way that the carrier comprises a substantially closed, hollow internal structure. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
