Patent number: 6312766Abstract: Ion beam deposition, using a carbon- and fluorine-containing source or sources, is used to form a fluorinated diamond-like carbon layer in a device, the FDLC layer exhibiting a dielectric constant of 3.0 or less along with a thermal stability of at least 400° C. During the ion beam deposition, due to the unique nature of carbon chemistry, the carbon atoms combine at the substrate surface to form all possible combinations of sp1, sp2 and sp3 bonds. However, ion beam etching occurs along with deposition, such that atoms of the weaker carbon structures—carbyne and graphite—are removed preferentially. This leads to a buildup of a diamond-like, sp3-bonded structure with fluorine atoms, it is believed, substituted for some carbon atoms within the structure, this structure providing the desirable properties of the layer.Type: GrantFiled: December 4, 1998Date of Patent: November 6, 2001Assignee: Agere Systems Guardian Corp.Inventors: Chien-Shing Pai, Wei Zhu

Patent number: 6312768Abstract: Powerful nanosecond-range lasers using low repetition rate pulsed laser deposition produce numerous macroscopic size particles and droplets, which embed in thin film coatings. This problem has been addressed by lowering the pulse energy, keeping the laser intensity optional for evaporation, so that significant numbers of the macroscopic particles and droplets are no longer present in the evaporated plume. The result is deposition of evaporated plume on a substrate to form thin film of very high surface quality. Preferably, the laser pulses have a repetition rate to produce a continuous flow of evaporated material at the substrate. Pulse-range is typically picosecond and femtosecond and repetition rate kilohertz to hundreds of megahertz.Type: GrantFiled: June 21, 2000Date of Patent: November 6, 2001Assignee: The Australian National UniversityInventors: Andrei Rode, Eugene Gamaly, Barry Luther-Davies

Patent number: 6312789Abstract: A recording sheet of the present invention comprises a substrate film, a receptor layer for retaining a toner image and a release layer for releasing the receptor layer from a fixing surface of a fixing means, the receptor layer and the release layer being disposed on at least one side of the substrate film in this order from a position of the substrate film, wherein the release layer contains a release agent having compatibility to toner and releasing ability to the fixing surface. A preferable release agent is wax, particularly wax having a polar group in its molecular structure, such as carnauba wax and candelilla wax. The recording sheet of the present invention can provide a high quality of the toner image with no occurrence of fusion to the fixing surface and cohesive failure of the receptor layer even when the thermal fixing is carried out with no oil supplied to the fixing surface of the fixing means.Type: GrantFiled: January 27, 1999Date of Patent: November 6, 2001Assignee: Dai Nippon Printing Co., Ltd.Inventors: Masafumi Hayashi, Noritaka Egashira

Patent number: 6312790Abstract: The present invention is directed to a method of and apparatus for forming a coating having at least one fade zone over a substrate. The method and apparatus include positioning a coating composition dispenser above a surface of a substrate with the coating composition dispenser oriented to dispense a coating composition spray generally normal to the surface of the substrate. A gas dispenser is also positioned above the surface of the substrate and adjacent the coating composition dispenser with the gas dispenser oriented to dispense a gas stream generally normal to the surface of the substrate. The coating composition spray and the gas stream are spaced from each other so as to develop an interference effect therebetween adjacent the surface of the substrate. Preferably the substrate is maintained at a temperature which pyrolyzes the coating composition. The interference effect directs the coating composition to deposit over the substrate as a coating having a fade zone.Type: GrantFiled: December 18, 1997Date of Patent: November 6, 2001Assignee: PPG Industries Ohio, Inc.Inventor: Luke A.

Patent number: 6312791Abstract: Disclosed is a multilayer ceramic substrate having an outer pad, for example an I/O pad, which is anchored to a middle pad of the multilayer ceramic substrate by a plurality of vias which in turn is anchored to an inner pad of the multilayer ceramic substrate by a second plurality of vias. The middle and outer pads and vias are made of high metal material, preferably 100% metal, so they won't adhere very well to the ceramic substrate. The inner pad is a composite metal/ceramic material which will bond very well to the ceramic substrate.Type: GrantFiled: August 25, 2000Date of Patent: November 6, 2001Assignee: International Business Machines CorporationInventors: Benjamin V. Fasano, David H. Gabriels, Richard F. Indyk, Sundar M. Kamath, Scott I. Langenthal, Srinivasa S. N. Reddy, Rao V. Vallabhaneni

Patent number: 6312798Abstract: Ion beam-deposited, nitrogen-doped C:H films having substantially lower resistivities than undoped ion beam-deposited C:H films and suitable for use as hard, abrasion-resistant overcoat layers for magnetic recording media, such as hard disks, are formed by supplying a mixture of hydrocarbon and nitrogen gases to an ion beam generator. Nitrogen atom content of the films is controlled to within from about 5 to about 25 at. % by appropriate selection of the ratio of hydrocarbon gas flow to nitrogen gas flow. The resultant IBD i-C:HN films exhibit a reduced tendency for charge build-up thereon during hard disk operation by virtue of their lower resistivity vis-à-vis conventional a-C:H materials.Type: GrantFiled: September 21, 1999Date of Patent: November 6, 2001Assignee: Seagate Technology LLCInventors: Xiaoding Ma, Kevin J.
