Patent number: 7917309Abstract: An apparatus and method for detection of airborne contaminants and prevention of influx of the contaminants into an enclosed space, such as a vehicle cabin. A first sensor array samples exterior air prior to influx of the exterior air into the enclosed space. The first sensor array generates data uniquely corresponding to each contaminant. Data corresponding to predetermined contaminants is stored in computer memory. A user may also cause data corresponding to a contaminant selected by the user to be stored in the computer memory. Upon identification of a contaminant, an actuator is operative to control a position of a valve to prevent influx of the exterior air into the enclosed space.Type: GrantFiled: December 11, 2007Date of Patent: March 29, 2011Assignee: International Business Machines CorporationInventor: Colin Brodsky

Publication number: 20070037325Abstract: A method of forming a thin film is provided in which a film having a first thickness is deposited over a substrate, wherein the first thickness is greater than a thickness at which the initially deposited film begins to dewet from the substrate. The initially deposited film is then stabilized to form a stabilized film. Thereafter, the stabilized film is then thinned to a second thickness, such that the resulting film now has a smaller thickness than the thickness at which the initially deposited film would begin to dewet from the substrate. However, as a result of the prior stabilization, the reduced thickness film remains free of dewetting defects.Type: ApplicationFiled: October 16, 2006Publication date: February 15, 2007Inventors: Wai-Kin Li, Colin Brodsky, Steven Scheer

Publication number: 20060154412Abstract: A method for reducing the size of a patterned semiconductor feature includes forming a first layer over a substrate to be patterned, and forming a photoresist layer over the first layer. The photoresist layer is patterned so as to expose portions of the first layer, and the exposed portions of the first layer are removed in a manner so as to create an undercut region beneath the patterned photoresist layer. The patterned photoresist layer is reflowed so as to cause reflowed portions of the patterned photoresist layer to occupy at least a portion of the undercut region.Type: ApplicationFiled: January 12, 2005Publication date: July 13, 2006Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Colin Brodsky, Scott Allen

Publication number: 20060147849Abstract: A method is provided for forming a stable thin film on a substrate. The method includes depositing a co-polymer composition having a first component and a second component onto a substrate to form a stable film having a first thickness. The first component has first dielectric properties not enabling the first component by itself to produce the stable film having the first thickness. However, the second component has second dielectric properties which impart stability to the film at the first thickness. In a preferred embodiment, the second component includes a leaving group, and the method further includes first thermal processing the film to cause a solvent but not the leaving group to be removed from the film, after which second thermal processing is performed to at least substantially remove the leaving group from the film. As a result, the film is reduced to a second thickness smaller than the first thickness, and the film remains stable during both the first and the second thermal processing.Type: ApplicationFiled: January 5, 2005Publication date: July 6, 2006Applicant: International Business Machines CorporationInventors: Steven Scheer, Colin Brodsky

Publication number: 20060003153Abstract: A film stack and method of forming a film stack are provided in which a first film is disposed on a substrate and a second film has an inner surface disposed on the first film. The second film has a thickness smaller than a reference thickness at which the second film would begin to dewet from the substrate if the second film were disposed directly on the substrate. However, the second film is substantially free of dewetting defects because it is disposed overlying the first film which has a first Hamaker constant having a negative value with respect to the substrate.Type: ApplicationFiled: June 30, 2004Publication date: January 5, 2006Applicant: International Business Machines CorporationInventors: Colin Brodsky, Wai-Kin Li, Steven Scheer
