摘要:
An article support (2) constructed to support an article for lithographic processing purposes is disclosed. The article support includes a channel configuration (1) arranged to guide thermally stabilizing media in the article support to provide thermal stabilization to the article, wherein the channel configuration comprises an input channel structure (9) and an output channel structure (10), the input and output channel structures arranged in a nested configuration and connected to each other by a fine grid structure (11) provided at or near a surface of the article support. A lithographic apparatus and device manufacturing incorporating the article support is also disclosed.
摘要:
A lithographic apparatus is disclosed having a deformable lens element through which a patterned radiation beam is arranged to pass before reaching a substrate and having a deformable lens actuator configured to transmit a combination of a force substantially parallel to the optical axis of the projection system and a localized torque about an axis substantially perpendicular to the optical axis independently at a plurality of sub-regions on the deformable lens element.
摘要:
A lithographic apparatus comprising: an illumination system (IL) configured to condition a radiation beam (PB); a support (MT) constructed to support a patterning device (MA), the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table (WT) constructed to hold a substrate (W); a projection system (PL) configured to project the patterned radiation beam onto a target portion of the substrate; a liquid supply system (130) configured to at least partly fill a space (25) between a final element of said projection system and said substrate with liquid; a seal member (12) arranged substantially to contain said liquid within said space between said final element of the projection system and said substrate; and elements (30,50,60,120,140) to control and/or compensate for evaporation of immersion liquid from said substrate.
摘要:
In a lithographic projection apparatus a liquid supply system maintains liquid in a space between the final element of the projection system and the substrate of the lithographic projection apparatus. A shutter member (150) is provided to take the place of the substrate in containing the liquid (11) in the liquid supply system during substrate exchange.
摘要:
Liquid is supplied to a reservoir (10) between the final element of the projection system (PS) and the substrate by an inlet (21,22). An overflow removes the liquid above a given level. The overflow is arranged above the inlet and thus the liquid is constantly refreshed and the pressure in the liquid remains substantially constant.
