摘要:
An immersion lithographic apparatus is disclosed that includes a fluid supply system configured to supply a fluid, the fluid supply system having a chamber with a plurality of inlet holes in a first side wall and a plurality of outlet holes in a second side wall, the first side wall facing the second side wall, wherein the inlet holes direct fluid entering the chamber in a direction towards areas of the second side wall between the plurality of outlet holes.
摘要:
A fluid handling structure configured to supply immersion liquid to a space defined between a projection system and a facing surface facing the fluid handling structure is disclosed. An undersurface of the fluid handling structure has a supply opening configured to supply fluid toward the facing surface, a plurality of extraction openings configured to remove fluid from between the fluid handling structure and the facing surface, and a protrusion between the supply opening and the extraction openings.
摘要:
An immersion lithographic apparatus is disclosed having a projection system configured to direct a patterned beam of radiation onto a substrate and a liquid handling system configured to supply and confine immersion liquid to a space defined between the projection system and a substrate, or a substrate table, or both. A controller is provided to adjust an angle of a lower surface of the liquid handling system relative to the top surface of the substrate during motion of the substrate and/or substrate table relative to the liquid handling system dependent upon a position of the substrate and/or substrate table relative to the liquid handling system and/or a direction of relative movement between the substrate and/or substrate table and the liquid handling system.
摘要:
A toner dam maintenance process and system model the amount of toner mass at a toner cleaner blade, and apply a corrective procedure, such as insertion of a paperless copy into the print job mid-job or immediately prior to cycle out, to replenish the toner mass at the cleaner blade to maintain lubrication and reduce cleaning failure. The modeling includes contributing factors toward toner dam input and output, including untransferred toner, cycle-in/cycle-out bands, untransferred background, and leakage of toner from the cleaner blade. One or several threshold can be reached to cause one or more different corrective actions to take place. The action may be adding or skipping a pitch to insert a corrective maintenance pattern without transfer.
