The electro-optical structure comprises a top optically transmissive conductor, a bottom optically transmissive conductor positioned below and parallel to the top conductor so as to define a space therebetween, the space including the first region and the second region, and an electric voltage applicator coupled to the top conductor and adapted to apply an electric voltage to the top conductor that creates the electric potential between the top and bottom conductors. An apodizable, variable aperture stop with no moving parts is also disclosed.Type: GrantFiled: March 19, 2003Date of Patent: July 17, 2007Assignee: The Boeing CompanyInventor: Mark A. Lundgren

Patent number: 7245348Abstract: A coating and developing system includes an auxiliary block, a resist film forming unit block and antireflection film forming unit blocks stacked up in layers to form a resist film and an antireflection film underlying the resist film and an antireflection film overlying the resist film in a small space. The coating and developing system can cope with either a case where antireflection films are formed or a case where no antireflection film is formed. Film forming unit blocks, namely, a TCT layer, a COT layer and a BCT layer, and developing unit blocks, namely, DEV layers, are stacked up in layers in a processing block S2. The TCT layer, the COT layer and the BCT layer are used selectively in the case where antireflection films are formed and the case where any antireflection film is not formed. The coating and developing system is controlled by a carrying program.Type: GrantFiled: April 29, 2005Date of Patent: July 17, 2007Assignee: Tokyo Electron LimitedInventors: Masami Akimoto, Shinichi Hayashi, Yasushi Hayashida, Nobuaki Matsuoka, Yoshio Kimura, Issei Ueda, Hikaru Ito

Patent number: 7245353Abstract: To compensate for birefringence of a mask in a lithographic projection apparatus, the birefringence of a mask is measured and stored as birefringence data in a data storage device. A birefringent compensation element is disposed in the optical path of the lithographic projection apparatus. Appropriate adjustments of the compensation element are determined as those optimally reducing impact of the mask birefringence on the state of polarization at substrate level.Type: GrantFiled: October 12, 2004Date of Patent: July 17, 2007Assignee: ASML Netherlands B.V.Inventors: Johannes Catharinus Hubertus Mulkens, Wil{acute over (h)}elmus Petrus De Boeij, Carsten Andreas Kohler

Patent number: 7245354Abstract: A system and method for optimizing an illumination source to print a desired pattern of features dividing a light source into pixels and determining an optimum intensity for each pixel such that when the pixels are simultaneously illuminated, the error in a printed pattern of features is minimized. In one embodiment, pixel solutions are constrained from solutions that are bright, continuous, and smooth. In another embodiment, the light source optimization and resolution enhancement technique(s) are iteratively performed to minimize errors in a printed pattern of features.Type: GrantFiled: January 21, 2005Date of Patent: July 17, 2007Inventor: Yuri Granik

Patent number: 7245356Abstract: A method of configuring a transfer of an image of a patterning device pattern onto a substrate with a lithographic apparatus. The method includes determining an intermediate illumination arrangement parameter and an intermediate patterning device parameter by varying an initial illumination arrangement parameter and an initial patterning device parameter using a calibrated model until the calculated image of the pattern printed on the substrate is within predetermined specification; calculating a metric that represents a lithographic response of the printed pattern over a process range, where the pattern would be imaged with the intermediate illumination arrangement and patterning device parameters over the process range, and depending on a result of the metric, adjusting the initial patterning device and illumination arrangement parameters.Type: GrantFiled: November 17, 2005Date of Patent: July 17, 2007Assignee: ASML Netherlands B.V.Inventor: Steven George Hansen

Patent number: 7245358Abstract: The present invention includes a substrate support system that features a chuck body having a body surface with a pin extending therefrom having a contact surface lying in a plane, with the pin being movably coupled to the chuck body to move with respect to the plane. As a result the substrate support system attenuates if not avoids generating non-planarity in a substrate that results from a presence of particulate contaminants. This is achieved by fabricating the pin to be compliant, allowing the same to move to accommodate the presence of the particle while maintaining sufficient planarity in the substrate.Type: GrantFiled: May 25, 2005Date of Patent: July 17, 2007Assignee: Board of Regents, The University of Texas SystemInventors: Pawan Kumar Nimmakayala, Sidlgata V.
