Patent number: 9103012Abstract: A method of activating a copper seed layer during a plating process is disclosed that comprises application of vapor generated by an ultrasonic wave nebulizer. The energized vapor droplets include water and a weak organic acid such as acetic acid, lactic acid, citric acid, uric acid, oxalic acid, or formic acid that have a vapor pressure proximate to that of water. The weak organic acid preferably has a pKa high enough to avoid Cu etching but is sufficiently acidic to remove copper oxide at a rate that is compatible with high throughput manufacturing. In one embodiment, weak acid/water vapor is applied to a substrate in a spin bowl and is followed by a deionized water rinse step in the same spin bowl. Improved wettability results in improved uniformity in subsequently plated copper films. Considerable cost savings is realized as a result of reduced chemical consumption and higher product yields.Type: GrantFiled: February 11, 2011Date of Patent: August 11, 2015Assignee: Headway Technologies, Inc.Inventors: Chao-Peng Chen, Jas Chudasama, Chien-Li Lin, David Wagner

Patent number: 9085828Abstract: A mold is fabricated with a cavity formed in an insulating layer formed so as to be placed on an upper surface of a conductive base material. This mold is disposed in an electrolyte bath to be applied with a voltage, and a metal is electrodeposited on the bottom surface of the cavity to electroform a metal-formed product in the cavity. In this electrodepositing process, when the width of the cavity is taken as W and a vertical height of a head space between an upper opening of the cavity and an upper surface of a metal layer is taken as H, the growth of the metal layer is stopped so that the height H of the head space left above the metal layer satisfies: where 300 ?m?W; H?W/3.75 where 200 ?m?W<300 ?m; H?W/4 where 100 ?m?W<200 ?m; and H?W/10 where W<100 ?m.Type: GrantFiled: September 11, 2009Date of Patent: July 21, 2015Assignee: OMRON CorporationInventors: Kazumasa Seki, Akihiko Hatamura, Hitoshi Yoshida, Toshio Yamashita, Yasuhiro Miura

Patent number: 9081006Abstract: The present invention concerns methods, compositions and apparatus for detection and/or determination of concentration of target molecules. In preferred embodiments the methods comprise allowing target molecules to form a complex with a first binding agent conjugated to a detection molecule and a second binding agent conjugated to a capture molecule, allowing the complex to further bind to an essentially uncharged polymer capable of binding to the capture agent, and performing a vertical gradient electrophoresis to separate the complex from unbound target, first and second binding agents and polymer. The intact complex is concentrated by electrophoresis at a stacking layer and the detection molecule is detected and/or quantified. Because the complex contains a very high mass to charge ratio, it becomes essentially immobile at the stacking layer, while unbound components migrate through the stacking layer and are separated from the complex.Type: GrantFiled: January 31, 2008Date of Patent: July 14, 2015Assignee: LYZER DIAGNOSTICS, INC.Inventors: Steven Patrick Tyrrell, Barry Vant-Hull

Patent number: 9080970Abstract: A device for controlled transport of ions is provided comprising an ion source element and an ion target element both conducting ions of a first class e.g. cations, and an ion selective element which conducts ions of a second class e.g. anions. The device further comprises a transport element, which receives ions from the ion source element and releases them to the ion target element in response to an electrochemical potential difference provided across the ion transport element. In use a first electrochemical potential is applied to the control element, which increases the concentration of ions of said second class, which increased concentration in turn increases the ion transport rate of ions of said first class in the ion transport element.Type: GrantFiled: April 14, 2010Date of Patent: July 14, 2015Assignee: OBOE IPR ABInventors: Klas Tybrandt, Magnus Berggren

Patent number: 9074288Abstract: A prefabricated sacrificial galvanic anode panel includes a rigid or semi-rigid backing board or similar support surface over which a thin layer of cement, mortar or adhesive is applied for holding a compliant layer of material in place on the support surface. The layer of wet adhesive, cement or mortar is sufficiently thin so that upon drying it does not cause warping of the support surface. The compliant or spongy layer is laminated or sandwiched between a thicker layer of ionically conductive galvanic mortar and the substrate support surface. The compliant or spongy layer prevents the thicker layer of galvanic mortar from wetting the backing board or substrate support surface so as to prevent warpage upon drying of the thicker layer of galvanic mortar and also accommodates the expansion of corrosion products from the galvanic anode material.Type: GrantFiled: July 12, 2012Date of Patent: July 7, 2015Assignee: Jarden Zinc Products, LLCInventor: Derek C.
