Patent number: 9620410Abstract: Methods for processing a microelectronic topography include selectively etching a layer of the topography using an etch solution which includes a fluid in a supercritical or liquid state. In some embodiments, the etch process may include introducing a fresh composition of the etch solution into a process chamber while simultaneously venting the chamber to inhibit the precipitation of etch byproducts. A rinse solution including the fluid in a supercritical or liquid state may be introduced into the chamber subsequent to the etch process. In some cases, the rinse solution may include one or more polar cosolvents, such as acids, polar alcohols, and/or water mixed with the fluid to help inhibit etch byproduct precipitation. In addition or alternatively, at least one of the etch solution and rinse solution may include a chemistry which is configured to modify dissolved etch byproducts within an ambient of the topography to inhibit etch byproduct precipitation.Type: GrantFiled: January 20, 2009Date of Patent: April 11, 2017Assignee: Lam Research CorporationInventors: Mark I. Wagner, James P. DeYoung

Patent number: 8961701Abstract: Drying a microelectronic topography. At least some of the illustrative embodiments are methods that include placing a microelectronic topography inside a process chamber, providing a non-aqueous liquid to the process chamber until at least 90% of the volume of the process chamber contains the non-aqueous liquid, pressurizing the process chamber by way of a fluid different than the non-aqueous liquid, ceasing activity with respect to the process chamber until the non-aqueous liquid and fluid form a mixture that is substantially homogenous, venting the process chamber while simultaneously providing the fluid to the process chamber, and venting the process chamber in a manner which prevents formation of liquid in the process chamber.Type: GrantFiled: September 18, 2009Date of Patent: February 24, 2015Assignee: Lam Research CorporationInventors: Mark I.

Patent number: 8153533Abstract: Methods for preventing feature collapse subsequent to etching a layer encasing the features include adding a non-aqueous liquid to a microelectronic topography having remnants of an aqueous liquid arranged upon its surface and subsequently exposing the topography to a pressurized chamber including a fluid at or greater than its saturated vapor pressure or critical pressure. The methods include flushing from the pressurized chamber liquid arranged upon the topography and, thereafter, venting the chamber in a manner sufficient to prevent liquid formation therein. The topography features may be submerged in a liquid while pressurizing the chamber. A process chamber used to prevent feature collapse includes a substrate holder for supporting a microelectronic topography, a vessel configured to contain the substrate holder, and a sealable region surrounding the substrate holder and the vessel. The chamber is configured to sequester wet chemistry supplied to the vessel from metallic surfaces of the sealable region.Type: GrantFiled: September 24, 2008Date of Patent: April 10, 2012Assignee: Lam ResearchInventors: James P.
