Publication number: 20120223047Abstract: Methods of forming embedded, multilayer capacitors in printed circuit boards wherein copper or other electrically conductive channels are formed on a dielectric substrate. The channels may be preformed using etching or deposition techniques. A photoimageable dielectric is an upper surface of the laminate. Exposing and etching the photoimageable dielectric exposes the space between the copper traces. These spaces are then filled with a capacitor material. Finally, copper is either laminated or deposited atop the structure. This upper copper layer is then etched to provide electrical interconnections to the capacitor elements. Traces may be formed to a height to meet a plane defining the upper surface of the dielectric substrate or thin traces may be formed on the remaining dielectric surface and a secondary copper plating process is utilized to raise the height of the traces.Type: ApplicationFiled: October 22, 2010Publication date: September 6, 2012Applicant: Endicott Interconnect Technologies, Inc.Inventors: Rabindra N.

A step of horizontally holding a substrate and rotating the substrate around a vertical axis at a prescribed rotation rate, and a step of intermittently supplying a developing solution to a center of the substrate from a discharge port of a developing solution nozzle arranged opposing to the surface of the substrate are executed. In the step of intermittently supplying the developing solution to the center of the substrate, an intermittence time and a substrate rotation rate in the intermittence time are set to prevent the developing solution supplied to the substrate from drying.Type: GrantFiled: April 25, 2007Date of Patent: August 17, 2010Assignee: Tokyo Electron LimitedInventor: Kousuke Yoshihara

Patent number: 7709184Abstract: A method of on-press developing a thermosensitive lithographic printing plate with ink and/or fountain solution is described. The lithographic plate comprises on a substrate a thermosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to an infrared radiation. The printing plate can be a pre-coated plate in the form of sheet or web, or can be prepared on press by coating a thermosensitive layer onto a substrate that is a sheet material or a seamless sleeve mounted on a plate cylinder or is the surface of a plate cylinder of the lithographic press.Type: GrantFiled: July 17, 2006Date of Patent: May 4, 2010Inventor: Gary Ganghui Teng

Publication number: 20100068664Abstract: A developing roller has a mandrel, an elastic layer and a cover layer as a surface layer. The cover layer includes a silicon oxide film containing a carbon atom chemically bonded to a silicon atom. In the silicon oxide film, the proportion of the total number of the elements of silicon, oxygen, carbon and hydrogen to the number of all detected elements, as detected with a high-frequency glow discharge light-emission surface analysis method, is 90% or more. The silicon oxide film has an abundance ratio of an oxygen atom chemically bonded to a silicon atom to silicon atoms, (O/Si), of 0.65 or more but 1.95 or less and an abundance ratio of a carbon atom chemically bonded to a silicon atom to silicon atoms, (C/Si), of 0.05 or more but 1.65 or less, and has a ratio of the maximum value to the minimum value of the (C/Si) in a thickness direction of the cover layer, of 1.50 to 33.00.Type: ApplicationFiled: September 3, 2009Publication date: March 18, 2010Applicant: CANON KABUSHIKI KAISHAInventors: Yosuke Ata, Genya Anan

Publication number: 20100047725Abstract: In a developing method for performing developing treatment of a substrate by supplying a developing solution onto a resist film formed on a surface of the substrate, the present invention controls a zeta potential of the surface of the substrate at a predetermined potential in the same polarity as that of a zeta potential of insoluble substances floating in the developing solution, thereby preventing or reducing the adhesion of the insoluble substances to the resist film and the substrate. This remedies the occurrence of development defects. The adhesion of the insoluble substances to the resist film and the substrate can also be prevented or inhibited by supplying an acid liquid to a liquid on the substrate, or controlling a pH value of the liquid on the substrate to control an absolute value of the zeta potential of the insoluble substances.Type: ApplicationFiled: October 30, 2009Publication date: February 25, 2010Applicant: TOKYO ELECTRON LIMITEDInventors: Yuko ONO, Junichi Kitano

Publication number: 20090130614Abstract: A developer nozzle is moved from a periphery of a wafer toward the central portion while an exposed substrate held at a spin chuck is being rotated about a vertical axis and while a developing solution is being discharged from the developer nozzle, and this way the developing solution is supplied to the surface of the wafer, the developer nozzle having a slit-like ejection port whose longitudinal direction is oriented to the direction perpendicular to the radial direction of the wafer. The movement speed of the nozzle is higher than a case where a nozzle with a small-diameter circular nozzle is used, and this enables a development time to be reduced. Further, the thickness of a developing solution on a substrate can be reduced, so that the developing solution can be saved.Type: ApplicationFiled: December 24, 2004Publication date: May 21, 2009Applicant: TOKYO ELECTRON LIMITEDInventors: Atsushi Ookouchi, Taro Yamamoto, Hirofumi Takeguchi, Hideharu Kyouda, Kousuke Yoshihara
