Patent number: 8161984Abstract: In an example embodiment, a device for generating a cleaning foam includes a female housing and a male plug. The plug includes an aperture into which a fluid flows from another component of the cleaning system. The plug includes a premix chamber which receives the fluid from the aperture and into which a gas is injected to form a foam. In an example embodiment, the chamber is a hollow cylinder and the gas is injected into the cylinder through channels which are tangential to the cylinder. The plug also includes a solid cylinder with a continuous helical indentation on the outside of the solid cylinder. When the male plug is inserted into the female housing, the continuous helical indentation and the inner surface of the housing form a helical channel through which the foam flows and is further mixed on its way back into the cleaning system.Type: GrantFiled: August 4, 2008Date of Patent: April 24, 2012Assignee: Lam Research CorporationInventors: Arnold Kholodenko, Anwar Husain, Gregory A.

Patent number: 7998304Abstract: Methods configure a proximity head for conditioning fluid flow relative to a proximity head in processing of a surface of a wafer by a meniscus. The methods configure the head in one piece while maintaining head rigidity even as the head is lengthened for cleaning of large diameter wafers. The one-piece head configuring separates main fluid flows from separate flows of fluid relative to the wafer surface, with the separation being by a high resistance fluid flow configuration, resulting in substantially uniform fluid flows across increased lengths of the head in a unit for either fluid supply or return.Type: GrantFiled: December 19, 2008Date of Patent: August 16, 2011Assignee: Lam Research CorporationInventors: Arnold Kholodenko, Cheng-Yu (Sean) Lin

Publication number: 20110100399Abstract: In an example embodiment, a wet system delivers a flow of cleaning foam through a channel in a proximity head to a meniscus interfacing with a semiconductor wafer. The wet system diverts a sample of the flow from the channel through a transparent cell that is connected to the channel by an input passage that leads from the channel to the transparent cell and by an output passage that leads from the transparent cell back to the channel. The wet system illuminates the sample in the transparent cell with an LED from the top or the back and captures an image of the illuminated sample with a CCD camera. The image shows a morphological attribute of the cleaning foam such as bubble diameter or spacing. The wet system generates a statistical characterization from the morphological attribute and adjusts other attributes of the cleaning foam based on the statistical characterization.Type: ApplicationFiled: November 5, 2009Publication date: May 5, 2011Applicant: Lam Research CorporationInventors: Arnold Kholodenko, Gregrory A.

Patent number: 7699634Abstract: An electrical connector has a non-conductive outer housing and a spring-loaded conductive assembly mounted within. The non-conductive outer housing has a longitudinal axis along which the spring-loaded conductive assembly is allowed to move over a limited range, in either direction. The conductive assembly includes a conductive contact pad and an conductive elongated shaft which are mated together within the non-conductive outer housing. A spring mounted along the contact shaft and in abutment therewith biases the contact shaft in a direction away from the contact base. When the electrical connector is employed in a chamber lid of a chamber lid assembly having an integrated laminated heater, such as for use in conjunction with a wafer processing chamber, the spring biases a lower surface of the contact shaft against the heater.Type: GrantFiled: March 16, 2007Date of Patent: April 20, 2010Assignee: Lam Research CorporationInventors: Arnold Kholodenko, Russell Martin, John Rasnick, Christopher Kimball
