Publication number: 20170333936Abstract: An apparatus for forming selectively coated areas on a substrate comprises an extrudate remover configured to selectively remove coating from a selected portion of the substrate. A chuck is configured to secure the substrate. A coating die is arranged proximal the substrate and is in fluid communication with a source of fluid extrudate. During relative motion between the substrate and the coating die, fluid extrudate is deposited onto the substrate. A controller is configured to selectively control the relative motion between the substrate and coating remover, and to control operation of the extrudate remover. The invention also provides a method of forming selectively coated areas on a substrate comprising the steps of inducing relative movement between a coating dispenser and the substrate, applying fluid material from the coating dispenser onto the substrate during the relative movement, and selectively removing a portion of the applied fluid from the substrate.Type: ApplicationFiled: August 7, 2017Publication date: November 23, 2017Inventors: Gregory M.

Publication number: 20090194021Abstract: To date, it has been difficult to extrude precision films onto large substrates efficiently, thus, limiting the size of the substrate. One reason for the difficulty is natural sag or deflection in an extrusion head applying the film to the substrate. To counteract this deflection or sag, a crossbar has been designed that provides a substantially rigid platform to mount an extrusion head, which counteracts the deflection or sag, thus allowing for efficient extrusion of precision films over exceedingly large substrates.Type: ApplicationFiled: February 1, 2008Publication date: August 6, 2009Inventors: Scott Snodgrass, Gregory M.

Patent number: 7383967Abstract: A system for dispensing and filtering fluid is disclosed, in which the fluid flow path is substantially vertical from the fluid inlet through fluid dispense. Substantially all wetted surfaces are TeflonĀ® or some similar non-contaminating fluid, for applications such as cleanroom processes. A valve and a filter chamber are incorporated into a pump head to simplify the flow path and reduce potential contamination points. Preferred methods, and chips or other microelectronic devices fabricated from the apparatus or methods, are also disclosed.Type: GrantFiled: November 14, 2005Date of Patent: June 10, 2008Assignee: Entegris, Inc.Inventor: Gregory M.

Patent number: 7169229Abstract: The invention pertains to a coating apparatus and method in which most of the relative movement between a dispensing head and the substrate to be coated is provided by the coating head. The moving head configuration reduces the system footprint and diminishes leveling problems. A powered shuttle mechanism carries a dispensing head above a substrate to be coated while riding on a bearing located underneath the chuck holding the substrate thereby providing rigidity and reducing the system footprint. Chuck support is designed to accommodate anticipated vertical sag in the dispensing head by supporting the chuck at points along its periphery thereby permitting the chuck to sag in conjunction with the dispensing head. The shuttle mechanism is equipped with means for automatically adjusting the height of the dispensing head with respect to substrate to compensate for substrate placement error, substrate dimensional variation, and mechanical drift in the mechanical machine parts.Type: GrantFiled: February 11, 2003Date of Patent: January 30, 2007Assignee: FAStar, Ltd.Inventors: Gregory M. Gibson, Carl W. Newquist, John E. Hawes, Rene Soliz, Samer Mahmoud Kabbani, Scott A. Snodgrass, Altaf A. Poonawala, Darwin R. Frerking, Zi-Qin Wang, Ocie T. Snodgrass, Eric E. Anderson

Patent number: 7160389Abstract: The present invention relates to a system and method suitable for automatic cleaning of a coating or extrusion head of a coating apparatus. The invention includes a scrubbing station wherein a combination of physical contact and strong solvent solution combine to remove coating fluid from the exterior of an extrusion head. A second cleaning station, preferably a rinsing station then further cleans the head of coating fluid and removes solvent used at a first cleaning station. The solvent used at the rinsing station is preferably self-drying thereby obviating the need for any further cleaning action. The invention also provides for the ability to prime the coating bead at the extrusion head so as to have a fully formed bead ready before the head begins coating a substrate, thereby providing an even coating across said substrate. The priming operation preferably comprises holding the head steady over a rotating priming roller while extruding fluid preferably at a constant volumetric flow rate.Type: GrantFiled: December 3, 2002Date of Patent: January 9, 2007Assignee: FAStar, Ltd.Inventors: Gregory M.

Patent number: 6495205Abstract: Extrusion coating of circular and other substrates is taught with a linear extrusion head in a linear motion utilizing a chuck assembly providing a coating bead forming surface. The coating bead forming surface allows for the coating bead to be at a steady state at all points at which the extrusion head interfaces with the substrate during the linear motion. Various configurations of chuck assemblies are taught to allow for improved handling of the substrate, deploying of the chucks in existing machinery, and simplified cleaning of the coating bead forming surface. Additionally, adaptation of the chuck assembly for discouraging undesired migration of the coating material is taught.Type: GrantFiled: September 4, 1998Date of Patent: December 17, 2002Assignee: FAStar, Ltd.Inventors: Gregory M.

Patent number: 6475282Abstract: A control system for assisting in applying a uniform layer of liquid to a substrate. The control system monitors a fluid pump advantageously integrated directly with an extrusion head. The pump receives the material to be deposited from a remote reservoir and controls dispersion of fluid to the extrusion head. The pump dispense rate is controlled by hydraulic pressure selectively applied by a flow control motor. The control system ensures that a steady-state flow of the liquid is maintained while preventing transient perturbations during initial extrusion startup.Type: GrantFiled: January 8, 1999Date of Patent: November 5, 2002Assignee: FAStar, Ltd.Inventors: Ocie T.
