摘要:
A heat pipe to maintain an object at a substantially uniform temperature is disclosed. The heat pipe includes a chamber containing a liquid reservoir and a vapor space, part of the chamber being defined by a condensing surface, and a liquid transporter to apply a force additional to gravity to liquid to transport liquid away from the condensing surface towards the reservoir, wherein the condensing surface is shaped such that condensed liquid moves along it towards the liquid transporter.
摘要:
A lithographic apparatus is provided that includes a substrate holder configured to hold a substrate, and a heat pipe to maintain the substrate holder at a substantially uniform temperature. The heat pipe has a chamber containing a liquid reservoir and a vapor space, and a heating element at least partly in contact with liquid in the chamber.
摘要:
Methods and apparatus for maintaining the thermal equilibrium of a substrate and an immersion lithographic apparatus are disclosed using or having a timetable comprising information regarding the position, speed and/or acceleration of the substrate; and an evaporation controller and/or condensation controller acting to decrease localized evaporation and/or increase localized condensation in response to the information in the timetable. Evaporation of liquid from the surface of the substrate cools it down, while condensing liquid on its bottom surface heats the substrate locally.
摘要:
A lithographic apparatus configured to project a patterned radiation beam onto a target portion of a substrate held on a substrate holder in an indent on a substrate table, the apparatus includes a liquid supply system configured to at least partly fill a space between a projection system and the substrate with liquid; a barrier structure configured to substantially contain the liquid within the space; and a heat pipe supplied, in use, with a temperature conditioned fluid and configured to thermally condition the substrate and/or the substrate holder at locations where localized cooling is likely to occur.

摘要:
The invention relates to the field of biochemistry and medicine. More specifically the invention relates to methods and pharmaceuticals for the treatment of intestinal neoplasia. The invention discloses the surprising finding that inhibitors of Notch pathway activation (for example γ-secretase inhibitors) are extremely useful in the treatment of intestinal adenoma and/or adenocarcinoma.
