Patent number: 7636999Abstract: A method of retaining a substrate to a wafer chuck. The method features accelerating a portion of the substrate toward the wafer chuck, generating a velocity of travel of the substrate toward the wafer chuck, and reducing the velocity before the substrate reaches the wafer chuck. In this manner, the force of impact of the portion with the wafer chuck is greatly reduced, which is believed to reduce the probability that the structural integrity of the substrate, and layers on the substrate and/or the wafer chuck, are damaged.Type: GrantFiled: January 31, 2005Date of Patent: December 29, 2009Assignee: Molecular Imprints, Inc.Inventors: Byung-Jin Choi, Anshuman Cherala, Daniel A.

Patent number: 7224443Abstract: The present invention is directed to a chucking system to modulate substrates so as to properly shape and position the same with respect to a wafer upon which a pattern is to be formed with the substrate. The chucking system includes a chuck body having first and second opposed sides. A side surface extends therebetween. The first side includes first and second spaced-apart recesses defining first and second spaced-apart support regions. The first support region cinctures the second support region and the first and second recesses. The second support region cinctures the second recess, with a portion of the body in superimposition with the second recess being transparent to radiation having a predetermined wavelength. The second side and the side surface define exterior surfaces. The body includes throughways placing the first and second recesses in fluid communication with one of the exterior surfaces.Type: GrantFiled: March 27, 2006Date of Patent: May 29, 2007Assignee: Molecular Imprints, Inc.Inventors: Byung-Jin Choi, Ronald D.

Patent number: 7090716Abstract: The present invention is directed toward a method for reducing pattern distortions in imprinting layers by reducing gas pockets present in a layer of viscous liquid deposited on a substrate. To that end, the method includes varying a transport of the gases disposed proximate to the viscous liquid. Specifically, the atmosphere proximate to the substrate wherein a pattern is to be recorded is saturated with gases that are either highly soluble, highly diffusive, or both with respect to the viscous liquid being deposited. Additionally, or in lieu of saturating the atmosphere, the pressure of the atmosphere may be reduced.Type: GrantFiled: October 2, 2003Date of Patent: August 15, 2006Assignees: Molecular Imprints, Inc., Board of Regents, The University of Texas SystemInventors: Ian M.

Patent number: 6729462Abstract: The present invention is an edge grip aligner with buffering capabilities and a method for increasing the throughput of wafers through the device. According to one embodiment, the present invention has first and second buffer arms, and a chuck arm. A workpiece can be aligned while supported on the chuck arm. Once the workpiece is aligned, the chuck arm transfers the workpiece to the buffer arms so that a second workpiece can be aligned on the chuck arm. While the second workpiece is being aligned, an end effector can transfer the first workpiece away from the buffer arms and retrieve another workpiece to place upon the chuck arm.Type: GrantFiled: May 22, 2003Date of Patent: May 4, 2004Assignee: Asyst Technologies, Inc.Inventors: Daniel A.
