摘要:
A component for a lithography tool, the component including a member having a primary surface; a conduit defined within the member and configured to receive a fluid under pressure; a compressible region within the member and located between the conduit and the primary surface; and a deformable region between the compressible region and the conduit, wherein the compressible region and the deformable region are configured to accommodate local deformation of the member resulting from the pressure of the fluid.
摘要:
Embodiments of the present invention are directed to a system and a method of controlling the flow and pressure of immersion fluid to provide stable conditions for immersion lithography. An immersion fluid is provided in a space (34) between a last optical element of an optical projection system and a workpiece during the immersion lithography process. For this purpose,a nozzle (20) is provided configured to supply immersion fluid in the gap between the last optical element and the workpiece, wherein the nozzle includes an inner cavity (34) to retain the immersion fluid in the gap and an outer cavity (53) to recover immersion fluid that exits the inner cavity.

The present invention provides an exposure apparatus which forms a pattern on a substrate, the apparatus including an electron optical system (10) configured to guide a charged particle beam onto the substrate (ST), a stage (20) configured to hold the substrate, an electromagnetic actuator (32) configured to drive the stage, a magnetic shield (34) which is placed in the stage so as to surround the electromagnetic actuator, a measurement member (50) configured to measure a position of the stage, a coil member (60) configured to generate a magnetic field on a path of the charged particle beam between the electron optical system and the substrate, and a control member (90) configured to control the coil member so as to reduce a fluctuation of the magnetic field on the path, the magnetic field on the path fluctuating while the stage being driven by the electromagnetic actuator, based on the position of the stage measured by the measurement member.
摘要:
An exposure apparatus (EX) exposes a substrate (P) by projecting an image of a pattern on the substrate (P) via a projection optical system (PL) and a liquid (1). The exposure device (EX) has a liquid supply mechanism (10) which supplies the liquid (1) between the projection optical system (PL) and the substrate (P). The liquid feeding mechanism (10) stops the supply of the liquid (1) when abnormality is detected. This suppresses influence to devices and members in the periphery of the substrate caused by leakage of the liquid forming a liquid immersion area, thereby realizing satisfactory exposure processing.
