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: 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.

Patent number: 6387184Abstract: A system and method for modularly interfacing wet components of a coating apparatus to the remainder of the coating apparatus comprising a station whereupon a substrate is located. A fluid cart houses the wet components of the apparatus which comprise a dispensing head in fluid connection to the fluid cart. The fluid cart can be connected to a station and a variety of different types of coating operations subsequently performed. The fluid can be readily disconnected from the station after the coating operation is complete, permitting a different fluid cart to be attached to the same station. The first fluid cart can then receive required servicing without idling the station to which it had been attached. Various embodiments of the means for coating the substrate and powering and controlling equipment of the coating apparatus are disclosed.Type: GrantFiled: January 8, 1999Date of Patent: May 14, 2002Assignee: FAStar, Ltd.Inventors: Gregory M.

Patent number: 6092937Abstract: The inventive dispenser mechanism uniformly develops a photosensitive layer on a substrate. The mechanism uses a developer head that moves in a substantially linear relative motion with respect to the substrate and dispenses a developer at a controlled rate. Contact of the developer material with the photosensitive layer commences a chemical reaction of developing. The mechanism also uses a rinse head that has the same motion as the developer head and travels at the same velocity. The rinse head dispenses a rinse material at a controlled rate. Contact of the rinse material with the developer material on the photosensitive layer retards the chemical reaction of developing. The rinse head waits for a predetermined dwell period after the developer head has dispensed the developer material before dispensing the rinse material. The mechanism may also use a suction head that has the same motion and velocity and removes loose material on a surface of the substrate.Type: GrantFiled: January 8, 1999Date of Patent: July 25, 2000Assignee: FAStar, Ltd.Inventors: Ocie T.
