Patent number: 7921403Abstract: Impedance control, and the uniformity of electrical and mechanical characteristics in electronic packaging are becoming more important as chip and bus speeds increase and manufacturing processes evolve. Current state of the art design and manufacture processes inherently introduce physical dielectric thickness variations into PCB cross sections. These thickness variations between the ground reference plane(s) and the signal layer(s) inject undesirable characteristic impedance variations and undesirable mechanical variations in thickness and surface topology. Therefore a process of generating equalization data and a design structure for multilayer electronic structures is presented.Type: GrantFiled: April 11, 2008Date of Patent: April 5, 2011Assignee: International Business Machines CorporationInventors: John Richard Dangler, Matthew Stephen Doyle

Patent number: 7844422Abstract: The invention relates to a method of optimizing a state transition function specification for a state machine engine based on a probability distribution for the state transitions. For the preferred embodiment of the invention, a B-FSM state machine engine accesses a transition rule memory using a processor cache. The invention allows improving the cache hit rate by exploiting the probability distribution. The N transition rules that comprise a hash table entry will be loaded in a burst mode from the main memory, from which the N transition rules are transferred to the processor cache. Because the comparison of the actual state and input values against each of the transition rules can immediately start after each of these rules has been received, the overall performance is improved as the transition rule that is most likely to be selected is the first to be transferred as part of the burst access.Type: GrantFiled: April 26, 2007Date of Patent: November 30, 2010Assignee: International Business Machines CorporationInventors: Rolf Fritz, Markus Kaltenbach, Ulrich Mayer, Thomas Pflueger, Cordt Starke, Jan Van Lunteren

Patent number: 7727887Abstract: A first through via is electrically insulated from surrounding wafer substrate material. A second through via is not electrically insulated from the surrounding wafer substrate material. This configuration is advantageous when the non-insulated via serves as the path for either Vdd or GND. By not insulating the through via, a first supply voltage (Vdd or GND) is allowed to flow through the surrounding wafer substrate material thereby decreasing the resistance of the first supply voltage path.Type: GrantFiled: October 30, 2007Date of Patent: June 1, 2010Assignee: International Business Machines CorporationInventors: Todd Alan Christensen, John Edward Sheets, II

Patent number: 7703058Abstract: The invention relates to a method and system for the design and implementation of state machine engines. A first constraints checking step checks a state transition function created by a designer against constraints imposed by the implementation technology in order to detect all portions of the state transition function that are in conflict with the constraints. A subsequent conflict resolution step tries to determine one or more suggested ways to meet the conflicting constraints, by investigating how the original state transition function can be modified such that all constraints are met. A final presentation and selection step provides the designer textual and/or graphically results of the constraints check and suggested modifications. The modifications can be accepted interactively, or the state transition function can be changed manually. In the latter case, the modified state transition function will be processed starting again with the constraints checking step.Type: GrantFiled: April 26, 2007Date of Patent: April 20, 2010Assignee: International Business Machines CorporationInventors: Rolf Fritz, Markus Kaltenbach, Ulrich Mayer, Thomas Pflueger, Cordt Starke, Jan Van Lunteren

Patent number: 7682936Abstract: It is an object to reduce a thickness of a semiconductor component (chip) on a substrate to a predetermined thickness regardless of a variation in thickness of a substrate in a semiconductor product. In a semiconductor product mounted on a base plate, a surface of a semiconductor component on a substrate is set to be located at a predetermined height h from a surface of a base plate. Thereafter, through machining the surface of the semiconductor component which is adjusted to be located at the predetermined height, it is possible to make the thickness of the semiconductor component on the substrate equal to a predetermined thickness.Type: GrantFiled: September 18, 2007Date of Patent: March 23, 2010Assignee: International Business Machines CorporationInventors: Toshihiko Nishio, Yasumitsu Orii, Yukifumi Oyama

Patent number: 7672185Abstract: A monitor bank consists of test one time programmable memory that is programmed distinctively from functional one time programmable memory in order to determine whether the functional one time programmable memory has or will program successfully. In a specific embodiment, each monitor bank consists of a first eFuse configured to expectedly never blow, a second eFuse configured to expectedly always blow, and at least a third eFuse configured to be more difficult to blow than the first eFuse, but easier to blow than the second eFuse. The method of determining whether functional eFuses have or will be programmed successfully is described: programming a monitor bank; sensing whether the test eFuses have blown; creating a monitor bank bit line blow pattern; determining an anticipated bit line blow pattern; comparing the two patterns; and determining that the functional eFuses will not blow successfully if the patterns do not match.Type: GrantFiled: January 3, 2007Date of Patent: March 2, 2010Assignee: International Business Machines CorporationInventors: David H.
