    Abstract: A method for separating integrated circuit dies from a wafer includes making at least two cutting passes with a laser along a first die street of an integrated circuit die, the first die street extending along a first axis on the wafer. The method also includes making at least two cutting passes with the laser along a second die street of the integrated circuit die, the second die street extending along a second axis on the wafer that is generally perpendicular to the first axis. In one process, three cutting passes are made with the laser alternatingly along the first and second die streets to separate the integrated die circuit along the first and second axes. In another process, two cutting passes are made with the laser along the first die street in opposite directions, and two cutting passes are then made with the laser along the second die street in opposite directions.

  • Publication number: 20150144174
    Abstract: A crystalline silicon ingot is produced using a directional solidification process. In particular, a crucible is loaded with silicon feedstock above a seed layer of uniform crystalline orientation. The silicon feedstock and an upper part of the seed layer are melted forming molten material in the crucible. This molten material is then solidified, during which process a crystalline structure based on that of the seed layer is formed in a silicon ingot. The seed layer is arranged such that a {110} crystallographic plane is normal to the direction of solidification and also so that a peripheral surface of the seed layer predominantly also lies in a {110} crystallographic plane. It is found that this arrangement offers a substantial improvement in the proportion of mono-crystalline silicon formed in the ingot as compared to alternative crystallographic orientations.

  • Patent number: 8688306
    Abstract: Aspects of the present disclosure relate generally to limiting the use of an autonomous or semi-autonomous vehicle by particular occupants based on permission data. More specifically, permission data may include destinations, routes, and/or other information that is predefined or set by a third party. The vehicle may then access the permission data in order to transport the particular occupant to the predefined destination, for example, without deviation from the predefined route. The vehicle may drop the particular occupant off at the destination and may wait until the passenger is ready to move to another predefined destination. The permission data may be used to limit the ability of the particular occupant to change the route of the vehicle completely or by some maximum deviation value. For example, the vehicle may be able to deviate from the route up to a particular distance from or along the route.

  • Patent number: 8677984
    Abstract: A method and apparatus for cutting rigid, brittle articles such as tile used as a building material is improved by the capability to make both straight and curved cuts in tile on a single machine. The machine has both circular and plunge cutting tools and a table for moving the tile in both curved and straight lines in relation to the cutting tool, thereby achieving both curved and straight cuts.

  • Publication number: 20140053822
    Abstract: Systems and methods of transferring loads between adjacent cast-in-place slabs, such as concrete slabs, and for accurately positioning dowels between adjacent sections of slabs are provided. A generally planar plate-type dowel is used which may be positioned within a cutaway in a preexisting slab of concrete. The dowel is shaped to generally conform to the shape of the cutaway, which is made by a saw blade. Once the dowel is positioned within the preexisting slab, a new slab is poured adjacent the preexisting slab. Rubber seals are included on the edges of the dowels to provide spacing or a gap between the dowel and the preexisting slab to allow for lateral independent movement of the adjacent slabs, and to prevent concrete from the newly poured second slab from entering into the gap. A saw unit for making a generally planar cut horizontally into an edge of a hardened concrete slab is also provided.

  • Patent number: 8656902
    Abstract: A tile saw comprises a frame, a primary table moveably supported by the frame for supporting a work-piece to be cut, a water tray located under the primary table, a supporting arm mounted on the frame, and a cutting device supported by the supporting arm. The primary table also includes first and second connecting edges and a secondary table which may be removably attached, without the use of tools, to either the first or second connecting edge of the primary table. When the secondary table is attached, the supporting area for the work-piece is increased resulting in increased stability and increased cutting accuracy.

  • Publication number: 20130333681
    Abstract: A method is described for producing a sawing bead for use in a sawing cord. Sawing cords are used for cutting hard and brittle materials. In the method, laser cladding is used to form an abrasive layer on a small metallic tube (204) or sleeve. The abrasive layer (220) comprises a metal matrix material in which abrasive particles such as diamond, cubic boron nitride or other hard cutting materials are embedded. The metal matrix material preferably comprises an active metal that improves wetting and adhesion of the abrasive particles. Although the abrasive particles are relative large—with a particle size in excess of 100 ?m—they are evenly distributed throughout the abrasive layer. This is achieved by letting the tube (204) rotate relative to the laser cladding system possibly in combination with a relative axial movement so that the cladding track loops on itself thereby forming an abrasive layer (220). Additionally the method allows to shape the sawing bead for improved geometrical tolerances and centricity.

  • Publication number: 20130319391
    Abstract: The present invention is for the recovery of maximum silicon value of kerf silicon waste, produced during the manufacture of silicon wafers by wire saw, diamond saw and chemical mechanical polishing, as high purity metallurgical silicon. This recovery is achieved by a process scheme that effects an initial removal of minor extrinsic metallic impurities but not the major silicon compound impurities, and followed, preferentially, by a direct metallurgical process to form elemental silicon. The recovered silicon is for use as feedstock for polysilicon manufacturing, as high purity polysilicon for PV application, and in metallurgical alloy manufacture.
