Patent number: 9068273Abstract: A method of cleaning metal-containing deposits from a metal surface of a process chamber component includes immersing the metal surface in an electrochemical cleaning bath solution. A negative electrical bias is applied to the metal surface to electrochemically clean the metal-containing deposits from the metal surface. The cleaning method is capable of removing metal-containing deposits such as tantalum-containing deposits from the metal surface substantially without eroding the surface, and may be especially advantageous in the cleaning of components having textured surfaces.Type: GrantFiled: June 10, 2011Date of Patent: June 30, 2015Assignee: Quantum Global Technologies LLCInventors: Hong Wang, Kenneth Tsai

Patent number: 8397381Abstract: A method for manufacturing a light set with surface mounted light emitting components is disclosed. A rod having a predetermined length and a winding control architecture with corresponding driving spindles are prepared first. The rod is driven to rotate by a winding machine via driving spindles to wind conducting wires. The insulating layer of each conducting wire is then ground along an axial direction of the rod to expose the conductor of each conducting wire to form contact-pad area. A conductive paste is applied to each contact-pad area, and the surface mounted light emitting components are straddled thereon. Each lead of the surface mounted light emitting components is respectively positioned corresponding to the contact-pad areas, and is electrically connected to the conductors by the conductive paste. The contact-pad areas and the surface mounted light emitting component are then covered with a package.Type: GrantFiled: August 6, 2009Date of Patent: March 19, 2013Assignee: Allied Bright Technology LimitedInventor: Kenneth Tsai

Publication number: 20060024440Abstract: A method of forming a coating on a component surface comprises placing a shield about the component surface to define a process zone, controlling the level of oxygen present in the process zone, generating an electric arc in the process zone to form a liquefied material from an electrode, and injecting a carrier gas into the process zone to direct the liquefied material toward the component surface. The level of oxygen present in the process zone is controlled by (i) filling the process zone with a non-oxidizing gas and maintaining a pressure p1 in the process zone higher than a pressure p2 of an ambient environment external to the process zone, and (ii) lining the process zone with an oxygen-absorbing material. Additionally, an arc spray apparatus comprises the shield comprising the oxygen-absorbing material and a consumable electrode extending into the process zone.Type: ApplicationFiled: July 27, 2004Publication date: February 2, 2006Inventors: Kenneth Tsai, Kenny Ngan
