The post-processing systems include a housing, a part retaining device to retain the part within the housing, and an actinic radiation source to cure the part with actinic radiation. The systems also include a fluid circulation device adapted to expose the part to cleaning fluid and/or to allow the cleaning fluid to absorb actinic radiation to permit filtration of removed build material to allow extended use of the cleaning fluid. Certain systems include a first rotating portion that can rotate the retained part about a first axis, and further systems include a second rotating portion that can rotate the retained part about a second axis. The systems also include additional features to provide safe and efficient cleaning and/or curing of parts produced by SFF.Type: ApplicationFiled: May 16, 2008Publication date: November 19, 2009Inventors: Khalil Moussa, Abraham N.

Patent number: 7604013Abstract: A cleaning method highly effectively cleans a surface of a semiconductor wafer by removing a dissolution product, produced when a surface of a semiconductor wafer is processed by a developing process that develops an exposed film formed on the semiconductor wafer by wetting the exposed film with a developer, from the surface of the semiconductor wafer. A cleaning liquid is poured through a cleaning liquid pouring nozzle onto a central part of a rotating wafer processed by a developing process to spread the cleaning liquid in a film over the surface of the wafer. Then, the cleaning liquid pouring nozzle is shifted to create a dry area in a central part of the wafer and the wafer is rotated at 1500 rpm to expand the dry area.Type: GrantFiled: March 9, 2005Date of Patent: October 20, 2009Assignee: Tokyo Electron LimitedInventors: Junji Nakamura, Kousuke Yoshihara, Kentaro Yamamura, Fumiko Iwao, Hirofumi Takeguchi

Publication number: 20090229639Abstract: A particle purge system purges particles from an electronic device. The electronic device is inverted and secured to an interface plate included with the system. A clean purge fluid is injected into an inlet of the interface plate to release and remove particles in the electronic device. The particle purge system agitates the electronic device to enhance the release of particles from components in the electronic device into the purge fluid. At least a portion of the purge fluid that contains the released particles is exhausted through an outlet in the interface plate.Type: ApplicationFiled: March 14, 2008Publication date: September 17, 2009Applicant: Seagate Technology LLCInventors: Tommy Joe Metzner, Nathaniel Patrick Sheppleman, Dennis Quinto Cruz, Sumit Chandra

Publication number: 20090173358Abstract: Megasonic cleaning systems and methods of using megasonic pressure waves to impart cavitation energy proximate a surface of a microelectronic substrate are disclosed herein. In one embodiment, a megasonic cleaning system includes a process tank for containing a liquid, a support element for carrying a substrate submerged in the liquid, and first and second transducers positioned in the tank. The first transducer is further positioned and/or operated to initiate cavitation events in a bulk portion of the liquid proximate a surface of the substrate. The second transducer is further positioned and/or operated to control an interface of fluid friction between the substrate and the bulk portion of the liquid.Type: ApplicationFiled: January 9, 2008Publication date: July 9, 2009Applicant: Micron Technology, Inc.Inventor: Nishant Sinha

Patent number: 7524771Abstract: Particles adhering to the surface of a substrate are removed by physical action of injection of droplets or megasonic vibrations or by combination of the physical action and slight etching on the surface of the substrate. On the other hand, metal contaminants adhering to the surface of the substrate are altered to hydroxides with an alkaline solution and thereafter dissolved with an acid solution to be removed. Thus, it is possible to rapidly process the substrate while minimizing the quantity of etching on the surface of the substrate.Type: GrantFiled: October 22, 2003Date of Patent: April 28, 2009Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Akira Izumi, Kenichi Sano

Publication number: 20080276959Abstract: The invention relates to the continuous cleaning of objects, in particular of semiconductor elements, using ultrasound, wherein the objects to be cleaned are arranged within a liquid. Furthermore, the present invention relates to an apparatus for carrying out the method according to the invention. A basic idea of the invention is that the surface of an object to be cleaned (2) in a tank (5) filled with liquid passes through at least one oscillation maximum that is emitted by at least one sound source (8a) being present in the tank (5). According to one embodiment, the sound source fields (8) that are positioned within the tank (5) are arranged inclined with respect to the transport direction (4).Type: ApplicationFiled: March 15, 2006Publication date: November 13, 2008Inventors: Norbet Burger, Mirko Lohmann, Richard Herter
