Disclosed herein are laser scanning systems and methods of their use. In some embodiments, laser scanning systems can be used to ablatively or non-ablatively scan a surface of a material. Some embodiments include methods of scanning a multi-layer structure. Some embodiments include translating a focus-adjust optical system so as to vary laser beam diameter. Some embodiments make use of a 20-bit laser scanning system.
Calibration Validation In Galvanometric Scanning Systems
Some embodiments may include a method of generating assessment data in a system including a galvanometric scanning system (GSS) having a laser device to generate a laser beam and an X-Y scan head module to position the laser beam on a work piece. The method may include selecting a dimension based on a desired accuracy for validation (and/or a characteristic of an imaging system in embodiments that utilize an imaging system). The method may include commanding the GSS to draw a mark based on a polygon or ellipse of the selected dimension around a predetermined target point associated with the work piece to generate assessment data, and following operation of the GSS based on said commanding, validating a calibration of the GSS using the assessment data (or an image thereof in embodiments that utilize an imaging system). Other embodiments may be disclosed and/or claimed.
Focus Assessment In Dynamically Focused Laser System
Some embodiments may include a method assessing whether a dynamic focus module in a three axis galvanometric scanning system (three-axis GSS) is associated with a focus calibration error. The method may include identifying a reference layer associated with a surface of the work piece and positive and negative offset distances each a difference distance above or below the reference layer, respectively, and selecting a target pattern based on the offset distances, wherein the pattern includes an individual line for each offset distance. The method may include commanding the three-axis GSS to draw the target pattern on the work piece, and then assessing whether the dynamic focus module is associated with the focus calibration error by correlating laser marking artifacts on the work piece to ones of the individual lines of the selected pattern. Other embodiments may be disclosed and/or claimed.

H01L 21/268 H01L 21/02 B23K 26/00 B23K 26/0622
Abstract:
Laser pulses from pulsed fiber lasers are directed to an amorphous silicon layer to produce a polysilicon layer comprising a disordered arrangement of crystalline regions by repeated melting and recrystallization. Laser pulse durations of about 0.5 to 5 ns at wavelength range between about 500 nm and 1000 nm, at repetition rates of 10 kHz to 10 MHz can be used. Line beam intensity uniformity can be improved by spectrally broadening the laser pulses by Raman scattering in a multimode fiber or by applying varying phase delays to different portions of a beam formed with the laser pulses to reduce beam coherence.

International Classification:
G02B 26/10 G01B 11/00
Abstract:
A method includes determining a set of pattern position errors between (i) a set of expected pattern positions of a calibration pattern on a laser target situated in a laser processing field of a laser system and produced based on a set of initial scan optic actuation corrections associated with a scan optic of the laser system and (ii) a set of measured pattern positions of the calibration pattern, determining a set of scan optic actuation rates based on the set of initial scan optic actuation corrections, and updating the set of initial scan optic actuation corrections based on the set of scan optic actuation rates and the set of pattern position errors so as to form a set of updated scan optic actuation corrections that is associated with a reduction of at least a portion of the set of pattern position errors.
Multi-Function Semiconductor And Electronics Processing
A method of tailoring beam characteristics of a laser beam during fabrication of an electronic device. The method includes: providing a substrate comprising one or more layers; adjusting one or more characteristics of a laser beam; and impinging the laser beam having the adjusted beam characteristics on the substrate to carry out at least one process step for fabricating the electronic device. The adjusting of the laser beam comprises: perturbing the laser beam propagating within a first length of fiber to adjust the one or more beam characteristics of the laser beam in the first length of fiber or a second length of fiber or a combination thereof, the second length of fiber having two or more confinement regions; coupling the perturbed laser beam into the second length of fiber; and emitting the laser beam having the adjusted beam characteristics from the second length of fiber.
Multi-Operation Laser Tooling For Deposition And Material Processing Operations
Disclosed herein are methods, apparatus, and systems for a multi-operation optical beam delivery device having a laser source to generate the optical beam. A beam characteristic conditioner that, in response to a control input indicating a change between the different laser process operations, controllably modifies the beam characteristics for a corresponding laser process operation of the different laser process operations. A delivery fiber has an input end coupled to the beam characteristic conditioner and an output end coupled to a process head for performing the corresponding laser process operation.

Yazidis Mark Second Anniversary of Islamic State Massacre
Today, as a somber occasion, we remember Yazidi victims of Daesh [IS] and its hateful ideology, Ken Gross, the consul general in Irbil, the capital of Iraqs Kurdistan region, said during a speech at Lalish Temple.
"I think the legal term is s*** show," said Ken Gross, an election law specialist at Skadden and former associate general counsel of the Federal Election Commission. "I think it's going to be a circus, to say the least."
"It could strengthen the hands of the outside groups if this becomes a viable vehicle for Wall Street to participate in the elections," said Ken Gross, a former associate general counsel at the Federal Election Commission who advises campaigns on campaign finance law.
Washington attorney Ken Gross said Monday that if Jackson Jr. pleads guilty, that pension is in jeopardy because of a law that strips pensions from lawmakers convicted of an array of public corruption crimes.
Bringing the case was a black eye for the Justice Department, said Ken Gross, a campaign finance lawyer who briefly served as a consultant to Edwardss defense team. This makes it that much worse that the jury saw through it.
