Patent number: 8932701Abstract: An optical sheet suitable for use in a laminate comprising at least one glazing component. The optical sheet comprises a non-metallic multi-layer optical film that has multiple optical layers, and can be, for example, a solar energy reflective film (e.g., an infrared radiation reflective film). The multiple layers are thermally and/or otherwise fused together along all, substantially all or at least a substantial portion of the peripheral edge of at least the optical film, so as to prevent or at least substantially reduce the occurrence or degree of delamination of the multiple layers along all, substantially all, or the substantial portion of the peripheral edge of the optical film.Type: GrantFiled: February 23, 2004Date of Patent: January 13, 2015Assignee: 3M Innovative Properties CompanyInventors: Heather K. Kranz, Jeffrey A. Boettcher, Janet R. Kirkman, Peter T. Dietz

Publication number: 20120094487Abstract: The method of the present invention comprises providing a wafer including a first, second and third material; contacting the third material in the presence of a working liquid with abrasive composites fixed to an abrasive article; and moving the wafer until an exposed surface of the wafer is substantially planar and comprises at least one area of exposed third material and one area of exposed second material. The components of the working liquid include an aqueous solvent; a pH buffer exhibiting a pKa greater than 7 and comprising a basic pH adjusting agent and a multidentate acidic complexing agent; and a non-ionic surfactant. The nonionic surfactant exhibits a hydrophile-lipophile balance of at least about 4.

Patent number: 7189447Abstract: A transparent optical film laminate and a method of making such a laminate. The laminate can include a transparent optical sheet comprising a non-metallic multi-layer optical film sandwiched between first and second bonding sheets. The optical sheet and the bonding sheets are also sandwiched between two glazing components. A substantial portion of the peripheral edge of the optical film lies within or beyond the peripheral edge of at least one of the glazing components. The peripheral edge of the optical film may have a portion that lies within and a portion that lies beyond the peripheral edge of at least one of the glazing components.Type: GrantFiled: January 4, 2002Date of Patent: March 13, 2007Assignee: 3M Innovative Properties CompanyInventors: Thomas J. Conway, Janet R. Kirkman, Brian L. Koster, Heather K. Kranz, Bruce E. Tait, Einar O. Vaage

Patent number: 6797396Abstract: A birefringent dielectric multilayer film that reflects in a wavelength region of interest, and preferably reflects at least 50% of light in a band at least 100 nm wide, preferably positioned between wavelengths from about 700 nm to about 2000 nm. The film is heat set to render the film capable of shrinking to conform without substantial wrinkling to a substrate having a compound curvature. The film may be laminated to form a wide variety of non-planar articles.Type: GrantFiled: June 9, 2000Date of Patent: September 28, 2004Assignee: 3M Innovative Properties CompanyInventors: Yaoqi J. Liu, Jeffrey A. Boettcher, Heather K. Kranz, Andrew T. Ruff, Brian L. Koster, David K. Mortenson

Patent number: 6194317Abstract: This invention pertains to a method of modifying or refining a surface of a wafer suited for semiconductor fabrication. This method may be used to modify a wafer having an unmodified, exposed surface comprised of a layer of a second material deployed over at least one discrete feature of a first material attached to the wafer. A first step of this method comprises contacting and relatively moving the exposed surface of the wafer with respect to an abrasive article, wherein the abrasive article comprises an exposed surface of a plurality of three-dimensional abrasive composites comprising a plurality of abrasive particles fixed and dispersed in a binder and maintaining contact to effect removal of the second material. In a second step, the contact and relative motion are continued until an exposed surface of the wafer has at least one area of exposed first material and at least one area of exposed second material.Type: GrantFiled: June 24, 1998Date of Patent: February 27, 2001Assignee: 3M Innovative Properties CompanyInventors: David A.
