Patent number: 7681308Abstract: A method of fabricating a semiconductor integrated circuit device uses a mold which is provided with a plurality of air vents and movable pins which are formed such that the movable pins include grooves in the distal ends thereof which project into the air vents. By clamping the mold in a state such that the distal ends of the movable pins are pushed against a multi-cavity board at the time of clamping the mold, resin can be filled while leaking air inside the cavity through the grooves formed in the distal ends of the movable pins by setting the depths of the respective air vents to a fixed value irrespective of the irregularities in thickness of the multi-cavity boards. Accordingly, it is possible to prevent insufficient filling of resin in the cavity, the leaking of resin or defective welding, whereby the yield rate of products can be enhanced.Type: GrantFiled: May 9, 2008Date of Patent: March 23, 2010Assignees: Renesas Eastern Japan Semiconductor, Inc., Renesas Technology CorporationInventors: Bunshi Kuratomi, Fukumi Shimizu

Patent number: 7681309Abstract: A method is disclosed that can be used to interconnect an integrated circuit (IC) multiple die assembly to conductors on a substrate such that signals can be conveyed between the dies and the conductors on the substrate. The multiple die assembly can include a first IC die and at least one secondary IC die, which can be mounted on a surface of the first IC die. Signal paths can be provided between the first IC die and the secondary IC die. The method can include providing conductive contacts on the surface of the first IC die. Each such conductive contact can have a free end extending outward from the surface beyond the secondary IC die. The method can also include mounting the multiple die assembly on the substrate such that the free end of each contact is brought into contact with the conductors on the substrate. The secondary IC die can reside between the surface of the first IC die and the substrate, and the contacts can convey signals between the first IC die and the conductors on the substrate.Type: GrantFiled: March 25, 2005Date of Patent: March 23, 2010Assignee: FormFactor, Inc.Inventor: Charles A.

Patent number: 7681310Abstract: A method is provided for fabricating a double-sided wiring board for mounting an electronic component thereon having metal wiring patterns formed both on upper and lower sides of an electrically-insulating board. The metal wiring patterns are electrically connected each other through a through-hole and/or a blind via-hole. The method has the steps of: laminating a metal layer with a support substrate on at least one side of the electrically-insulating board; removing the support substrate from the metal layer so that the metal layer is left on the electrically-insulating board; and forming the through-hole and/or the blind via-hole in the electrically-insulating board.Type: GrantFiled: October 21, 2005Date of Patent: March 23, 2010Assignee: Hitachi Cable, Ltd.Inventors: Akira Chinda, Nobuaki Miyamoto

Patent number: 7681311Abstract: A multi-tool process station includes a tool sub-station having a plurality of electrically powered tools moveable between an operating position and a ready position; a voltage source spaced therefrom by a distance; at least one controller spaced from the tool sub-station and in communication with the tools; a cable structure extending across the distance and having not more than one outer cable sheath at any point along the distance, the cable structure supplying power from the voltage source to a plurality of the tools and further carrying control signals to the plurality of tools. The cable structure may consist of a single continuous cable, or may comprise multiple cable segments, such as first and second cables connected in series. The tool sub-station may be disposed proximate a vehicle manufacturing line and the plurality of tools comprise at least a plurality of screw spindles.Type: GrantFiled: July 27, 2004Date of Patent: March 23, 2010Assignee: Cooper Power Tools GmbH & Co.Inventor: Ulrich Kaminski

Patent number: 7681312Abstract: A substrate, preferably constructed of a ductile material and a tool having the desired shape of the resulting device for contacting contact pads on a test device is brought into contact with the substrate. The tool is preferably constructed of a material that is harder than the substrate so that a depression can be readily made therein. A dielectric (insulative) layer, that is preferably patterned, is supported by the substrate. A conductive material is located within the depressions and then preferably lapped to remove excess from the top surface of the dielectric layer and to provide a flat overall surface. A trace is patterned on the dielectric layer and the conductive material. A polyimide layer is then preferably patterned over the entire surface. The substrate is then removed by any suitable process.Type: GrantFiled: July 31, 2007Date of Patent: March 23, 2010Assignee: Cascade Microtech, Inc.Inventors: Reed Gleason, Michael A. Bayne, Kenneth Smith, Timothy Lesher, Martin Koxxy

Patent number: 7681313Abstract: A method for forming heat exchanger plates (10) comprises formation of a fluid flow channel (28) along the edges (22) of a sheet metal strip or blank, and formation of a pair of raised end bosses. The raised end bosses (32) are elongated in the longitudinal dimension and are formed within the final width dimension of the plate so as to avoid the need for trimming of excess material along the edges of the plate. The method generates less scrap than prior art processes using progressive stamping, and also permits variation of the plate lengths.Type: GrantFiled: February 27, 2004Date of Patent: March 23, 2010Assignee: Dana Canada CorporationInventors: Peter Zurawel, Brian Ernest Duke, Raymond R.

Patent number: 7681314Abstract: According to the present invention, a razor cartridge includes a plurality of skin-engaging elements disposed on a frame. The skin engaging elements include at least two or more substantially blades having a sharpened cutting edge, a first inter-blade guard, and a cap. The two or more blades are disposed on the frame in parallel relation to one another. The first inter-blade guard is disposed on the frame between two (2) blades. A rinse-through gap extends across substantially the entire length of the frame between the first inter-blade guard and the blade aft the first inter-blade guard.Type: GrantFiled: June 10, 2005Date of Patent: March 23, 2010Assignee: Eveready Battery Company Inc.Inventor: Thomas A.

Patent number: 7681315Abstract: A clamping tool for use with a power tool includes a housing mounted on a power tool. The housing includes at least one engaging portion. The locking pliers includes a retaining section with a proximal end and a distal end. The proximal end is mounted on the at least one engaging portion for retain the locking pliers in a selectively, releasably, rotational relationship relative to the housing. An engaging section of the locking pliers is mounted relative to the retaining section and is selectively locked relative to the distal end of the retaining section for positioning an article therebetween. In two embodiments, after an article is locked in the locking pliers, the locking pliers can be rotated either away from or towards the housing to permit the power tool to come into engagement with an article.Type: GrantFiled: July 9, 2004Date of Patent: March 23, 2010Inventor: James Vanerd Wicklund, Jr.
