Patent number: 8046616Abstract: The present invention provides a method for controlling power change for a semiconductor module. Specifically, under the present invention power is applied to, or removed from a semiconductor module between a lower power state such as a zero power, nap or sleep state and a full power state over a predetermined time period. This allows the rate of movement and strain rate of the thermal interface material within the semiconductor module to be controlled, thus preserving the reliability of the material. Typically, the power is changed over time between the lower power state and the full power state in a linear fashion or incrementally.Type: GrantFiled: March 25, 2008Date of Patent: October 25, 2011Assignee: International Business Machines CorporationInventor: David L.

Patent number: 8021925Abstract: A semiconductor module structure and a method of forming the semiconductor module structure are disclosed. The structure incorporates a die mounted on a substrate and covered by a lid. A thermal compound is disposed within a thermal gap between the die and the lid. A barrier around the periphery of the die extends between the lid and the substrate, contains the thermal compound, and flexes in response to expansion and contraction of both the substrate and the lid during cycling of the semiconductor module. More particularly, either the barrier is formed of a flexible material or has a flexible connection to the substrate and/or to the lid. The barrier effectively contains the thermal compound between the die and the lid and, thereby, provides acceptable and controlled coverage of the thermal compound over the die for heat removal.Type: GrantFiled: December 13, 2007Date of Patent: September 20, 2011Assignee: International Business Machines CorporationInventors: David L. Edwards, Sushumna Iruvanti, Hilton T. Toy, Wei Zou

Patent number: 7900809Abstract: A method for assembling, and the resultant electronic module, includes attaching a chip to a substrate using a first solder interconnection array, and attaching a board to the substrate using a second solder interconnection array, which may be a single-melt or a dual-melt solder array. The second solder interconnection array resides entirely within a space defined between the board and substrate. A creep resistant structure is provided within this space for maintaining the defined space and optimizing integrity of the second solder interconnection array. The creep resistant structure may include an underfill material, balls, brackets, frames, collars or combinations thereof. Wherein the creep resistant structure is an underfill material, it is crucial that the substrate be attached to the board before either entirely encapsulating the second interconnection array with underfill material, or partially encapsulating the second solder interconnection array at discrete locations with underfill material.Type: GrantFiled: June 26, 2008Date of Patent: March 8, 2011Assignee: International Business Machines CorporationInventors: Glenn G.

Publication number: 20110042784Abstract: Embodiments of the invention are generally related to packaging of integrated circuit devices, and more specifically to the placement of thermal paste for cooling an integrated circuit device during operation. A barrier element may be placed along at least one side of an integrated circuit chip. The barrier element may contain thermal paste pumped out during expansion and contraction of the package components to areas near the chip. The barrier element may also form a reservoir to replenish thermal paste that is lost during thermal pumping of the paste.Type: ApplicationFiled: August 12, 2010Publication date: February 24, 2011Applicant: International Business Machines CorporationInventors: David L.

Patent number: 7733655Abstract: A method attaches a semiconductor chip to a substrate, applies a thermal interface material to a top of the semiconductor chip, and positions a lid over the semiconductor chip typically attached to the substrate with an adhesive. The method applies a force near the distal ends of the lid or substrate to cause a center portion of the lid or substrate to bow away from the semiconductor chip and increases the central thickness of the thermal interface material prior to curing. While the center portion of the lid or substrate is bowed away from the semiconductor chip, the thermal interface material method increases the temperature of the assembly, thus curing the thermal interface material and lid adhesive.Type: GrantFiled: July 22, 2008Date of Patent: June 8, 2010Assignee: International Business Machines CorporationInventors: Martin Beaumier, Mohamed Belazzouz, Peter J Brofman, David L Edwards, Kamal K Sikka, Jiantao Zheng, Jeffrey A Zitz

Patent number: 7724527Abstract: A method and structure of improving thermal dissipation from a module assembly include attaching a first side of at least one chip to a single chip carrier, the at least one chip having a second side opposite of the first side; grinding the second side of the at least one chip to a desired surface profile; applying a heat transfer medium on at least one of a heat sink and the second side of the at least one chip; and disposing the heat sink on the second side of the at least one chip with the heat transfer medium therebetween defining a gap between the heat sink and the second side of the at least one chip. The gap is controlled to improve heat transfer from the second side of the at least one chip to the heat sink.Type: GrantFiled: August 25, 2008Date of Patent: May 25, 2010Assignee: International Business Machines CorporationInventors: Patrick A.

Patent number: 7709951Abstract: Methods, apparatus and assemblies for enhancing heat transfer in electronic components using a flexible thermal pillow. The flexible thermal pillow has a thermally conductive material sealed between top and bottom conductive layers, with the bottom layer having a flexible reservoir residing on opposing sides of a central portion of the pillow that has a gap. The pillow may have roughened internal surfaces to increase an internal surface area within the pillow for enhanced heat dissipation. In an electronic assembly, the central portion of the pillow resides between a heat sink and heat-generating component for the thermal coupling there-between. During thermal cycling, the flexible reservoir of the pillow expands to retain thermally conductive material extruded from the gap, and then contracts to force such extruded material back into the gap. An external pressure source may contact the pillow for further forcing the extruded thermally conductive material back into the gap.Type: GrantFiled: March 16, 2007Date of Patent: May 4, 2010Assignee: International Business Machines CorporationInventors: William L. Brodsky, Peter J. Brofman, James A. Busby, Bruce J. Chamberlin, Scott A. Cummings, David L. Edwards, Thomas J. Fleischman, Michael J. Griffin, IV, Sushumna Iruvanti, David C. Long, Jennifer V.

Patent number: 7700615Abstract: Methods for treating an individual having cancer are provided. The method may include administering a cell migration inhibitor and a chemotherapeutic agent to the individual to inhibit migration of cancer cell. Inhibiting cell migration may increase cell division. In this manner, the cell migration inhibitor and the chemotherapeutic agent in combination may have increased efficacy compared to the chemotherapeutic agent alone due to the increased cell division. The cell migration inhibitor may include any of the inhibitors described herein. For example, the cell migration inhibitor may be an organic molecule having a molecular weight of less than about 700, a monoclonal antibody, or a natural product.Type: GrantFiled: February 1, 2006Date of Patent: April 20, 2010Assignee: Avolix Pharmaceuticals, Inc.Inventors: David L.

Patent number: 7687894Abstract: An IC chip package and related method are disclosed. The IC chip package may include a printed circuit board (PCB) coupled to a chip module by a land grid array (LGA) connector, a metal stiffener including a fluid-based pressure compensator contacting an underside of the PCB, and at least two couplers for coupling the metal stiffener to the chip module, with the PCB and the LGA connector therebetween. The fluid-based pressure compensator automatically compensates for natural and non-systematic out-of flatness tolerances of the PCB and the chip module, and non-uniform thickness of the PCB while creating a substantially uniform contact force on the LGA.Type: GrantFiled: September 27, 2006Date of Patent: March 30, 2010Assignee: International Business Machines CorporationInventors: John S.
