Patent number: 9367712Abstract: A memory card comprising a flexible substrate (a “flex”) which is integrated in the memory card and folded in a prescribed manner subsequent to having various active and passive devices (e.g., controller and memory devices) surface mounted thereto. The active and passive devices are attached to a common side of the flex, and electrically connected to a conductive pattern disposed thereon. The conductive pattern itself electrically communicates with external signal contacts also formed on the flex. The use of folded flex technology in the memory card of the present invention allows the same to support four or more standard, pre-packaged memory devices, thus providing the memory card with substantially increased capacity.Type: GrantFiled: March 1, 2007Date of Patent: June 14, 2016Assignee: Amkor Technology, Inc.Inventors: Lee J. Smith, Jeffrey Alan Miks, Curtis Michael Zwenger, Barry Michael Miles

Patent number: 8129824Abstract: A semiconductor device has a substrate. A first die is electrically attached to a first surface of the substrate. A shield spacer having a first and second surface is provided wherein the second surface of the shield spacer is attached to a first surface of the first die. A plurality of wirebonds are attached to the shield spacer and to the substrate. A mold compound is provided for encapsulating the first die, the shield spacer, and the wirebonds.Type: GrantFiled: December 3, 2008Date of Patent: March 6, 2012Assignee: Amkor Technology, Inc.Inventors: Roger D. St. Amand, Nozad O. Karim, Joseph M. Longo, Lee J. Smith, Robert F. Darveaux, Jong Ok Chun, Jingkun Mao

Patent number: 8089141Abstract: A semiconductor package including a leadframe which has one or more anchor pads formed on and/or defined by the die pad thereof. Such anchor pad(s) may be provided in any one of a multiplicity of different pad shapes, and are adapted to satisfy the required mechanical anchoring and thermal dissipation thresholds for the package, while still enabling high density circuit routing on the printed circuit board under the package. The leadframe of the semiconductor package further includes a plurality of leads which are segregated into at least two sets, with the leads of each set extending along and in spaced relation to respective ones of the peripheral edge segments defined by the die pad. Connected to the top surface of the die pad is at least one semiconductor die which is electrically connected to at least some of the leads of each set by conductive wires.Type: GrantFiled: January 25, 2010Date of Patent: January 3, 2012Assignee: Amkor Technology, Inc.Inventor: Lee J.

Patent number: 6650019Abstract: This invention provides a method for making a semiconductor package with stacked dies that eliminates fracturing of the upper die(s) during the wire bonding process. One embodiment of the method includes the provision of a substrate and pair of semiconductor dies, each having opposite top and bottom surfaces and a plurality of wire bonding pads around the peripheries of their respective top surfaces. One die is attached and wire bonded to a top surface of the substrate. A measured quantity of an uncured, fluid adhesive is dispensed onto the top surface of the first die, and the adhesive is squeezed toward the edges of the dies by pressing the bottom surface of the second die down onto the adhesive until the two dies are separated by a layer of the adhesive. The adhesive is cured, the second die is then wire bonded to the substrate, and the dies are then molded over with an encapsulant.Type: GrantFiled: August 20, 2002Date of Patent: November 18, 2003Assignee: Amkor Technology, Inc.Inventors: Thomas P. Glenn, Lee J. Smith, David A. Zoba, Kambhampati Ramakrishna, Vincent DiCaprio

Patent number: 5216922Abstract: A slope monitoring device includes a cable anchored at one end to the sloped wall of an open pit mine, dump, or the like. The cable extends over an idler pulley at the top of the sloped wall and passes around a further pulley coupled to an optical shaft encoder which generates a digital signal corresponding to the angular position of the pulley. The cable is engaged by a clutch and is wound about a play-off reel, each secured to a weighted sleeve slidingly extending about a vertical post. The weighted sleeve maintains tension upon the cable, while the clutch allows additional cable to be played off of the reel when tension is increased due to movement of the wall. The shaft encoder information, along with the temperature, battery condition, and cable condition, are transmitted by radio to a remote location for processing.Type: GrantFiled: December 4, 1991Date of Patent: June 8, 1993Assignee: Modular Mining Systems, Inc.Inventors: Eric S. Gustafson, Jonathan P. Olson, Lyle V. Johnson, Lee J. Smith
