Patent number: 6900991Abstract: To provide high-speed, low inductance capacitive decoupling, an integrated circuit (IC) package includes capacitors positioned within the mounting region between a die and an IC package substrate. A variety of types and sizes of capacitors and substrates can be employed in a variety of geometrical arrangements. In some embodiments, capacitors are sandwiched between die terminals or bumps and the substrate conductors or pads, while in other embodiments, capacitors are positioned between bar-type conductors on the surface of the IC package substrate. Methods of fabrication, as well as application of the package to an electronic assembly and to an electronic system, are also described.Type: GrantFiled: December 3, 2001Date of Patent: May 31, 2005Assignee: Intel CorporationInventors: Priyavadan R. Patel, Chee-Yee Chung, David G. Figueroa, Robert L. Sankman, Yuan-Liang Li, Hong Xie, William P. Pinello

Patent number: 6900529Abstract: An improved multi-chip module includes a main circuit board having an array of electrical interconnection pads to which are mounted a plurality of IC package units. Each IC package unit includes a pair of IC packages, both of which are mounted on opposite sides of a package carrier. The package units may be mounted on one or both sides of the main circuit board. A first primary embodiment of the invention employs a laminar package carrier having a pair of major planar surfaces. Each planar surface incorporates electrical contact pads. One IC package is surface mounted on each major planar surface, by interconnecting the leads of the package with the contact pads on the planar surface, to form the IC package unit. Several different variations of the chip module are disclosed.Type: GrantFiled: May 6, 2002Date of Patent: May 31, 2005Assignee: Legacy Electronics, Inc.Inventors: Kenneth J. Kledzik, Jason C. Engle

Patent number: 6891729Abstract: A memory module preferably includes a printed circuit board (PCB) panel having multiple memory chip pad groups arranged on both sides thereof. Each memory chip pad group preferably includes multiple pads that correspond to lead lines of multiple memory chips arranged on the PCB panel. Connectors are preferably formed along an edge of the PCB panel to electrically connect the memory chip pad groups to an external device. Multiple damping chip pad groups preferably include built-in damping chips. One or more of the damping chip pad groups are preferably arranged adjacent to a lateral edge of one or more of the memory chips. The damping chip pad groups can electrically connect the connectors to the memory chip pad groups and dampen the signal noises.Type: GrantFiled: July 16, 2002Date of Patent: May 10, 2005Assignee: Samsung Electronics Co., Ltd.Inventors: Ki-Hyun Ko, Kwang-Seop Kim

Patent number: 6877211Abstract: A method of making a microelectronic package. The advanced microelectronic component package incorporates a specially shaped base element which holds and electrically separates the individual conductors associated with the microelectronic component(s) so that the individual conductors may be bonded to external package leads and other conductors within the package. In a first embodiment, jacketed, insulated wire is used as one winding of a toroidal transformer, while unjacketed insulated wire is used as another winding. The jacketing is stripped from the first winding and the exposed conductors are routed into channels along the sides of the base element. The unjacketed conductors are also routed into the same channels, where both conductors are bonded to the external package leads. Raised elements along the sides of the base provide the required electrical separation between the conductors during both manufacture and operation. A method of manufacturing the improved microelectronic package is also disclosed.Type: GrantFiled: February 27, 2001Date of Patent: April 12, 2005Assignee: Pulse Engineering, Inc.Inventor: Russell Lee Machado
