Abstract:
PROBLEM TO BE SOLVED: To enable efficient cooling and stable positioning of an object that is a detector, such as a photodetector, disposed in a vacuum space. SOLUTION: A described cooling arrangement includes a heat sink having a first heat contact surface, an object having a second heat contact surface, and an elastic wall. The first heat contact surface and the second heat contact surface are set facing each other to form a gap. The elastic wall is part of an enclosure enclosing a space at least containing the gap. The cooling arrangement includes equipment that maintains a pressure difference between the space and an environment given by the cooling arrangement. A lithography apparatus includes this cooling arrangement. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
A cooling arrangement is described and includes a heat sink having a first thermal contact surface, an object having a second thermal contact surface and a resilient wall. The first thermal contact surface and the second thermal contact surface face each other and define a gap. The resilient wall is part of an enclosure that surrounds a space at least comprising the gap, and the cooling arrangement includes a facility to maintain a pressure difference between the space and an environment of the cooling arrangement. Additionally, a lithographic apparatus comprising such a cooling arrangement is described.
