  • Patent number: 7884919
    Abstract: A device manufacturing method includes transferring a pattern from a patterning device onto a substrate. The method includes bringing the patterning device and the support together, and applying a substantially stationary force between the patterning device and the support to hold the patterning device. The patterning device is now excited by a substantially dynamic force to enable a micro slipping thereof. Then, the patterning device is aligned, and the pattern is transferred from the patterning device onto the substrate. The patterning device may be excited with an alternating acceleration. When the patterning device is excited, the patterning device is allowed to settle with respect to the support, thereby improving a friction therebetween to reduce a risk of slipping or local slipping of the patterning device.

  • Publication number: 20110001955
    Abstract: Systems and methods to protect a mask from being contaminated by airborne particles are described. The systems and methods include providing a reticle secured in a two-part cover. The two part cover includes a removable protection device used to protect the reticle from contaminants. The cover can be held inside a pod or box that can be used to transport the cover through a lithography system from an atmospheric section to a vacuum section. While in the vacuum section, the removable cover can be moved during an exposure process during which a pattern on the reticle can be formed on a wafer.

  • Patent number: 7830498
    Abstract: A contact lithography apparatus, system and method use a hydraulic deformation to facilitate pattern transfer. The apparatus, system and method include a spacer that provides a spaced apart proximal orientation of lithographic elements, and a hydraulic force member that provides the hydraulic deformation. One or more of the lithographic elements and the spacer is deformable, such that hydraulic deformation thereof facilitates the pattern transfer.

  • Patent number: 7777864
    Abstract: A near-field exposure apparatus for exposing a substrate to light via an exposure mask under a condition that the exposure mask is close to the substrate. The apparatus includes a pressure adjustable container to control a relative position of the exposure mask to the substrate by adjusting a pressure of the pressure adjustable container. The pressure adjustable container has a structure adapted to be tightly closed with the exposure mask being held mounted so as to prevent volatile substances or foreign substances from entering into the pressure adjustable container. The pressure of the pressure adjustable container is adjustable through a change in capacity of the pressure adjustable container.

  • Patent number: 7740247
    Abstract: The present invention is a compound sliding seal unit of markedly reduced size and height dimensions which is employed as a discrete assembly for both the passage across and the at-will height adjustment of a mounted, rotatable shaft which extends from the atmospheric environment portion into the vacuum environmental portion of an ion implanter apparatus. The extended, rotatable shaft is typically fashioned as either a rotatable hollow tube or conduit (suitable for the passage of electrical components) and/or as a rotatable support suitable for the mounting of a pivotal scanning radial arm translation system. The manner of construction and the substantially reduced height dimensions of the compound sliding seal unit permits on-demand changes of height for the mounted, rotatable shaft which extends from the atmospheric environment and extends through the compound unit into the confined and limited spatial volume of a vacuum environment within a conventional ion implantation apparatus.

  • Patent number: 7702247
    Abstract: A latent image developer system and method is disclosed permitting the recovery of document impressions present in paper and other materials. The disclosed system utilizes two power supplies, a first power supply providing a plate bias charge which is applied to the document to be inspected, and a secondary power supply utilized to attract toner or other imaging powder attractant to the latent images present on the document to be inspected. The disclosed invention permits recovery of previously unrecoverable latent detail within documents as compared to the prior art which utilized a single power supply to promote toner to be attracted to the latent document images.
