Patent number: 6426860Abstract: The present invention provides for a device for holding a substrate in an exposure system. In the exposure system, the substrate is positioned on a table movable in the X and Y coordinates of an X, Y plane, and the exposure system provides a metering assembly between a table surface and the substrate to adjust the distance and to align the substrate in relation to an exposure optics, from where a corpuscular radiation is directed right-angled onto a substrate surface, corresponding to the Z coordinate. The device for holding the substrate includes two mounting plates aligned parallel to the X, Y plane, adjusted upon the table in a direction to the exposure optics and with different distances to the table surface, the first mounting plate of which being directly connected to the table.Type: GrantFiled: September 19, 2000Date of Patent: July 30, 2002Assignee: Leica Microsystems Lithography GmbHInventors: Gerhard Schubert, Ulf-Carsten Kirschstein, Stefan Risse, Gerd Harnisch, Gerhard Kalkowski, Volker Guyenot

Patent number: 4383771Abstract: The invention relates to a hydrodynamic fluid bearing of rotation symmetric shape constituted of a bearing member and a counter-bearing member the faces of each being in opposition to the other one at a narrow space. One of the members is provided with fluid pockets of levelling off depth in reverse direction to the direction of rotation of the bearing member. Thus it is feasible to cope with considerable bearing loads over a wide range of rotational speeds.Type: GrantFiled: October 20, 1981Date of Patent: May 17, 1983Inventors: Oskar Freytag, Rainer Bleyer, Volker Guyenot, Gerd Fleischer, Jugen Michael
