A brittle center member (such as glass) has a molded edge member. That edge member is ultrasonically welded to a body. The molded edge member and body are comprised of ultrasonically weldable materials. A hermetically sealed semiconductor package includes a lid with a brittle center plate and a molded edge. The molded edge is ultrasonically welded to a body. Locating features that enable accurate positioning of the lid relative to the body, and energy directors can be included. Pins having a relieved portion and a protruding portion can also be hermetically sealed to the body. Such pins can have various lengths that enable stadium-type pin rows. The pins can be within channels, which can hold a sealant. The body can include a device that is electrically connected to the pins.Type: GrantFiled: September 6, 2001Date of Patent: November 14, 2006Assignee: Silicon Bandwidth Inc.Inventors: Stanford W. Crane, Jr., Myoung-Soo Jeon, Matthew E. Doty

Patent number: 7088010Abstract: A system for chip packaging includes an adamantoid packaging composition. The adamantoid composition ameliorates the CTE mismatch that typically exists between a packaged die and a resin-impregnated fiberglass mounting substrate. In an embodiment, the system includes a packaging composition that alone exhibits a CTE that is characteristic of an inorganic-filled underfill composite previously known. An embodiment is also directed to the assembly of a chip package that uses an adamantoid packaging composition.Type: GrantFiled: December 18, 2003Date of Patent: August 8, 2006Assignee: Intel CorporationInventors: Sheau Hooi Lim, Choong Kooi Chee

Patent number: 7078730Abstract: To offer a semiconductor light-emitting device capable of preventing a short circuit failure caused by adhesion of the solder, change of a beam shape, and decrease of a beam output. A semiconductor laser device 1 is manufactured by overlaying a laser chip having a p-side electrode and a n-side electrode in a crystalline substrate and a mounting plate having a first solder film and a second solder film in a supporting body. The laser chip has a level difference A such that the p-side electrode is projected beyond the n-side electrode. The mounting plate has a level difference B such that the first solder film is projected beyond the second solder film. The level difference B of the mounting plate is determined as higher than the level difference A of the laser chip. Therefore, when the mounting plate is overlaid to the laser chip, first, the n-side electrode contacts with the second solder film, and then, the p-side electrode contacts the first solder film.Type: GrantFiled: December 18, 2003Date of Patent: July 18, 2006Assignee: Sony CorporationInventor: Masafumi Ozawa

Patent number: 7067903Abstract: A semiconductor device and package has a heat spreader directly disposed on the reverse surface of the semiconductor device. This heat spreader includes a diamond layer or a layer containing diamond and ceramics such as silicon carbide and aluminum nitride. The heat spreader is directly formed on a substrate for the semiconductor device. In particular, the heat spreader is composed of a diamond layer and one or two metal or ceramic members, which are bonded to the diamond layer with one or two polymer adhesive layers. This diamond layer has a fiber structure across the thickness or a microcrystalline structure. Cilia are formed on a surface of the diamond layer facing the one or two metal or ceramic members.Type: GrantFiled: November 6, 2003Date of Patent: June 27, 2006Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Takeshi Tachibana, Kazushi Hayashi, Kenichi Inoue, Yoshihiro Yokota, Koji Kobashi, Nobuyuki Kawakami, Takashi Kobori

Patent number: 7049695Abstract: A structure and method are provided for dissipating heat from a semiconductor device chip. A first layer of a dielectric material (e.g. polyimide) is formed on a front side of a heat spreader (typically Si). A plurality of openings are formed through this first layer; the openings are filled with metal (typically Cu), thereby forming metal studs extending through the first layer. A second layer of metal is formed on the backside of the device chip. The first layer and the second layer are then bonded in a bonding process, thereby forming a bonding layer where the metal studs contact the second layer. The bonding layer thus provides a thermal conducting path from the chip to the heat spreader.Type: GrantFiled: January 14, 2005Date of Patent: May 23, 2006Assignee: International Business Machines CorporationInventor: H. Bernhard Pogge

Patent number: RE39957Abstract: A method is provided of making a semiconductor package with a heat spreader in which a chip carrier module plate consisting of a plurality of array-arranged chip carriers is mounted with at least one chip on each of the chip carriers. A heat spreader module plate is attached to the chips, with an interface layer formed on a top surface of the heat spreader module plate. The chip carrier module plate, the chips and the heat spreader module plate are encapsulated. Adhesion force between the interface layer and the encapsulant is larger than that between the interface layer and the heat spreader module plate, and adhesion force between the interface layer and the heat spreader module plate is smaller than that between the heat spreader module plate and the encapsulant.Type: GrantFiled: September 3, 2004Date of Patent: December 25, 2007Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Chien-Ping Huang, Tzong-Da Ho, Cheng-Hsu Hsiao
