Patent number: 7078247Abstract: The integrity of a liner in an interconnect structure or other layer in an integrate circuit is tested in a short time by exposing the liner to a reactive gas that attacks the underlying silicon or other material behind the liner. A weak spot in the liner permits the gas to react with the silicon, which produces a visible area that can be readily identified. The test can be performed in a few hours, in contrast to a period of several months required to complete the process, package the circuit and conduct a burn-in test.Type: GrantFiled: June 6, 2003Date of Patent: July 18, 2006Assignee: International Business Machines CorporationInventors: Lawrence Bauer, Jr., Kenneth Giewont, Subramanian Iyer, Bosang Kim, Jeffrey Lloyd, Peter Locke, James Norum, Paul Parries, Kent Way, Kwong Hon Wong

Publication number: 20050193253Abstract: Disclosed is a flexible command multiplication scheme for the built-in-self test (BIST) of a high-speed embedded memory array that segments BIST functionality into remote lower-speed executable instructions and local higher-speed executable instructions. A stand-alone BIST logic controller operates at a lower frequency and communicates with a command multiplier using a low-speed BIST instruction seed set. The command multiplier uses offset or directive registers to drive a logic unit or ALU to generate ānā sets of CAD information which are then time-multiplexed to the embedded memory at a speed ānā times faster than the BIST operating speed.Type: ApplicationFiled: February 13, 2004Publication date: September 1, 2005Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jonathan Fales, Gregory Fredeman, Kevin Gorman, Mark Jacunski, Toshiaki Kirihata, Alan Norris, Paul Parries, Matthew Wordeman

Publication number: 20050157577Abstract: A concurrent refresh mode is realized by allowing a memory array to be refreshed by way of a refresh bank select signal, while concurrently enabling a memory access operation in another array. The refresh address management is greatly simplified by the insertion of row address counter integrated within each array. In the preferred embodiment, any combination of a plurality of the memory arrays is refreshed simultaneously while enabling a memory access operation. This concurrent mode also supports a multi-bank operation.Type: ApplicationFiled: January 15, 2004Publication date: July 21, 2005Inventors: John Barth, Toshiaki Kirihata, Paul Parries

Publication number: 20030123880Abstract: A programmable optical add/drop multiplexer (OADM) implements add/drop function of optical signals from a number of cross-connected optical systems while treating issues of coherent cross-talk, chromatic dispersion, slope of dispersion and amplitude equalization. Input WDM (wavelength division multiplexed) optical signals from a number of optical systems are each de-multiplexed into a number of optical path signal that are routed through switches and then multiplexed into a number of output WDM optical signals. Problems with coherent cross-talk in optical path signals are eliminated by introducing equivalent optical path lengths between paths through which the optical path signals propagate and by introducing dead-bands between consecutive optical path signals.Type: ApplicationFiled: December 28, 2001Publication date: July 3, 2003Inventors: David W. Boertjes, Mark R. Hinds, Kieran J. Parsons, Simon Paul Parry

Patent number: 6411417Abstract: An optical equalizer for a wavelength division multiplexed optical signal in an optical communications system utilises an array of parallel waveguides using planar waveguide technology. Waveguides having a range of different lengths have transmission controlled respectively in amplitude and/or phase in accordance with parameters calculated from a Fourier transform of an input frequency characteristic. Calculation of the parameters may be simplified by a Hilbert transform applied to determine phase values of the input terms of the Fourier transform. Feedback may be utilized by measuring the equalizer output and generating difference signals applied to the input to improve accuracy of equalization response by iteration or to overcome systematic errors. The equalizer has application to optical systems having line amplifiers where fiber amplifiers result in gain tilt, the equalizer allowing gain tilt to be corrected.Type: GrantFiled: September 22, 1998Date of Patent: June 25, 2002Assignee: Nortel Networks LimitedInventors: Kim Bryon Roberts, Simon Paul Parry, Alan Robinson

Patent number: 5976982Abstract: A method for preventing CMP-induced (chemical-mechanical polish) damage to a substrate disposed below a pad nitride layer of a mesa. The pad nitride layer is disposed below a conformally deposited dielectric layer. The dielectric layer is disposed below a conformally deposited polysilicon layer. The method includes planarizing the polysilicon layer down to at least a surface of the dielectric layer using the CMP to expose a first region of the dielectric layer. The method further includes etching partially through the first region of the dielectric layer using first etch parameters. The first etch parameters include an etchant source gas that is substantially selective to the pad nitride layer to prevent the pad nitride layer from being etched through even in the presence of a CMP defect. Additionally, there is also included removing the polysilicon layer after the etching partially through the first region of the dielectric layer.Type: GrantFiled: June 27, 1997Date of Patent: November 2, 1999Assignees: Siemens Aktiengesellschaft, International Business Machines CorporationInventors: Max G. Levy, Wolfgang Bergner, Bernhard Fiegl, George R. Goth, Paul Parries, Matthew J. Sendelbach, Tinghao T. Wang, William C. Wille, Juergen Wittmann

Patent number: 5466636Abstract: A semiconductor fabrication process for forming borderless contacts (130, 170, 172) using a removable mandrel (110). The process involves depositing a mandrel on an underlying barrier layer (100) designed to protect underlying structures (40) formed on a substrate (24). The mandrel is made from a material that will etch at a faster rate than the barrier layer so as to permit the formation of openings in the mandrel to be stopped on the barrier layer without penetrating such layer. After depositing a contact (130) in a first opening (120) formed in the mandrel, a second opening (140) is formed and a second contact (170) is deposited therein. Thereafter, the mandrel is removed and replaced with a layer of solid dielectric material (180).Type: GrantFiled: September 17, 1992Date of Patent: November 14, 1995Assignee: International Business Machines CorporationInventors: John E. Cronin, Carter W. Kaanta, Donald M. Kenney, Michael L. Kerbaugh, Howard S. Landis, Brian J. Machesney, Paul Parries, Rosemary A. Previti-Kelly, John F. Rembetski
