  • Patent number: 10310383
    Abstract: An exposure apparatus exposes a substrate with exposure light via a liquid. The exposure apparatus includes an optical system including an emission surface from which the exposure light is emitted; a liquid supply port that supplies the liquid in order to fill an optical path of the exposure light emitted from the emission surface with the liquid; and a fluid supply port that supplies a fluid including a material capable of changing the specific resistance of the liquid to at least a part of a space around a liquid immersion space that is formed by the liquid.
    Type: Grant
    Filed: August 28, 2017
    Date of Patent: June 4, 2019

  • Patent number: 9054140
    Abstract: Provided is a substrate holder system comprising a first substrate holder that holds a first substrate; an engaging member provided on the first substrate holder; a second substrate holder that holds a second substrate and can, together with the first substrate holder, sandwich the first substrate and the second substrate; an engagement receiving member that is provided on the second substrate holder and engages with the engaging member; and a dust restricting means for restricting generation of dust caused by the engagement of the engaging member and the engagement receiving member.

  • Publication number: 20120214290
    Abstract: Provided is a substrate holder pair comprising a first substrate holder that has a first holding portion holding a first substrate; a second substrate holder that has a second holding portion holding a second substrate to be bonded with the first substrate and that, together with the first substrate holder, sandwiches the first substrate and the second substrate; an engaging member that causes the first substrate holder to engage with the second substrate holder; and a dust inhibiting section inhibits dust generated by the engaging of the engaging member from entering between the first holding portion and the second holding portion.
