Patent number: 6504105Abstract: High melting temperature Pb/Sn 95/5 solder balls are connected to copper pads on the bottom of a ceramic chip carrier substrate by low melting temperature eutectic Pb/Sn solder. The connection is made by quick reflow to prevent dissolving Pb into the eutectic solder and raising its melting temperature. Then the module is placed on a fiberglass-epoxy circuit board with the solder balls on eutectic Pb/Sn solder bumps on copper pads of the board. The structure is reflowed to simultaneously melt the solder on both sides of the balls to allow each ball to center between the carrier pad and circuit board pad to form a more symmetric joint. This process results in structure that are more reliable under high temperature cycling.Type: GrantFiled: May 1, 1996Date of Patent: January 7, 2003Assignee: International Business Machines CorporationInventors: John Acocella, Donald Ray Banks, Joseph Angelo Benenati, Thomas Caulfield, Karl Grant Hoebener, David P. Watson, John Saunders Corbin, Jr.

Patent number: 6335494Abstract: Power layers of a multi-layer connection structure forming a power distribution network are partitioned to accommodate all necessary voltages for one or more chips connected thereto in each power layer. By doing so, and rearranging vias as permitted by such partitioning via length is reduced while via numbers can be increased to reduce self-inductance of the structure. Transmission lines formed by conductors in the signal layers are referenced to the correct power supply and return/image currents are made of similar path length and substantially symmetrical for both positive- and negative-going signal transitions. These effects reduce delta-I noise to levels which preserve good signal-to-noise ratios to current and foreseeable reduced signal levels.Type: GrantFiled: June 23, 2000Date of Patent: January 1, 2002Assignee: International Business Machines CorporationInventors: Roger P. Gregor, James P. Libous

Patent number: 6335637Abstract: The protection circuit of the present invention addresses the problem of indeterminate logic levels caused by loss of one of the power supplies in a two-power-supply CMOS integrated circuit. The circuit of the present invention replaces the typical scheme of power supply sequencing to fix the problem. The circuit disclosed herein detects the state of the core voltage and disables the output drivers when the core voltage is detected as being off. The disabled drivers are put into a high impedance state, thereby eliminating the potential for damage and eliminating the need for power supply sequencing. The invention also protects against the sudden loss of the integrated circuit core voltage, VDD, power supply during normal operation.Type: GrantFiled: April 3, 2000Date of Patent: January 1, 2002Assignee: International Business Machines CorporationInventors: Anthony Correale, Jr., Terry C.

Patent number: 6278735Abstract: A real-time single pass variable bit rate control strategy is provided to achieve variable bit rate (VBR) MPEG-2 encoding in a video compression system. For a sequence of frames, the level of encoding difficulty of a video interval (i.e., a group of pictures (GOP)) is determined by a perceptual rate-quantization ({overscore (C)}-{overscore (Q)}) model. This model assigns a composite ({overscore (C)}-{overscore (Q)}) curve to each video interval from which the number of bits for the video interval is estimated. The estimation relies on a causal predictive model using the parameters obtained from previously encoded video intervals. The R-Q relationship of each picture type is updated and picture bits are assigned, based on the total rate of the video interval under analysis. Robustness of the variable bit rate control strategy is ensured throughout scene transitions and instabilities by applying, for example, a non-linear median filter, and a low pass filter, respectively.Type: GrantFiled: March 19, 1998Date of Patent: August 21, 2001Assignee: International Business Machines CorporationInventor: Nader Mohsenian
