Patent number: 8379204Abstract: A method makes a discrete adjustment to static alignment of a laser beam in a machine for selectively irradiating conductive links on or within a semiconductor substrate using the laser beam. The laser beam propagates along a beam path having an axis extending from a laser to a laser beam spot at a location on or within the semiconductor substrate. The method generates, based on at least one measured characteristic of the laser beam, at least one signal to control an adjustable optical element of the machine affecting the laser beam path. The method also sends said at least one signal to the adjustable optical element. The method then adjusts the adjustable optical element in response to said at least one signal so as to improve static alignment of the laser beam path axis.Type: GrantFiled: August 15, 2008Date of Patent: February 19, 2013Assignee: GSI Group CorporationInventors: James J.

Patent number: 8367968Abstract: Laser pulses are selected from a group of closely spaced laser pulses with an optical modulator by adjusting pulse timing relative to an impingement interval. An adjusted pulse is moved from an impingement interval to a non-impingement interval and is blocked. The blocked laser source is stabilized by running nearly continuously. Pulse selection with multiple laser sources is achieved with a single acousto-optic modulator.Type: GrantFiled: January 3, 2008Date of Patent: February 5, 2013Assignee: GSI Group CorporationInventors: James Cordingley, Dimitry Maltsev, Michael Plotkin

Publication number: 20120241427Abstract: A method of processing material of device elements by laser interaction is disclosed. According to one aspect, the method includes generating a pulsed laser processing output along a laser beam axis, the output including a plurality of laser pulses triggered sequentially at times determined by a pulse repetition rate. A trajectory relative to locations of device elements to be processed is generated. A position of one or more designated device elements relative to an intercept point position on the trajectory at one or more laser pulse times is determined, and a laser beam is deflected based on the predicted position within a predetermined deflection range. According to some aspects, the predetermined deflection range may correspond to a compass rose or cruciform field shape. As a result, a deflection accuracy for laser processing may be improved.Type: ApplicationFiled: February 24, 2012Publication date: September 27, 2012Applicant: GSI Group CorporationInventors: Dimitry Maltsev, Dmitry N.

Patent number: 8243998Abstract: A method and apparatus are provided for evaluating the severity in a printed image of a repeating band print artifact. After electronically capturing the printed image, each of a plurality of patches taken from captured image is analysed to produce an artifact severity measure for the patch; an overall artifact severity value is then determined for the printed image from the patch severity measures. The analysis of each patch involves producing a spatial intensity profile across the patch substantially at right angles to an expected direction of extent of any repeating band print artifact present; a Fourier-related transform is then applied to the spatial intensity profile and the patch artifact severity measure generated by summing the resultant spatial frequency coefficients in a limited range about a frequency of interest.Type: GrantFiled: March 30, 2010Date of Patent: August 14, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alexander Berkovich, Hila Nachlieli, Shai Emanueli, Haim Vladomirski, Michael Plotkin

Patent number: 8085289Abstract: An optical beam is selectively output towards a scanner in accordance with image data for a scan line of an image. The optical beam has a beam irradiance distribution that is elliptical in shape. The optical beam passes through an aperture stop, ordinarily creating side lobes within a focus irradiance distribution of the optical beam. The scanner scans the optical beam to form the scan line on a photosensitive surface by selectively exposing positions along the scan line in accordance with image data. The optical beam is modified before it reaches the photosensitive surface to substantially remove the side lobes that have been created within the focus irradiance distribution and/or to substantially prevent the side lobes from being created within the focus irradiance distribution of the optical beam.Type: GrantFiled: October 24, 2008Date of Patent: December 27, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Dror Kella, Michael Plotkin, Shai Emanueli, Boris Aptekar, Haim Livne, Haim Vladomirski, David Kenney Towner
