Publication number: 20090280650Abstract: Methods of depositing and curing a dielectric material on a substrate are described. The methods may include the steps of providing a processing chamber partitioned into a first plasma region and a second plasma region, and delivering the substrate to the processing chamber, where the substrate occupies a portion of the second plasma region. The methods may further include forming a first plasma in the first plasma region, where the first plasma does not directly contact with the substrate, and depositing the dielectric material on the substrate to form a dielectric layer. One or more reactants excited by the first plasma are used in the deposition of the dielectric material. The methods may additional include curing the dielectric layer by forming a second plasma in the second plasma region, where one or more carbon-containing species is removed from the dielectric layer.Type: ApplicationFiled: September 15, 2008Publication date: November 12, 2009Applicant: Applied Materials, Inc.Inventors: Dmitry Lubomirsky, Qiwei Liang, Jang Gyoo Yang

Patent number: 7611752Abstract: A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.Type: GrantFiled: October 5, 2007Date of Patent: November 3, 2009Assignee: 3M Innovative Properties CompanyInventors: Robert J. Fleming, Joseph M. McGrath, Christopher S. Lyons
