  • Patent number: 8092601
    Abstract: A substrate processing system includes a source unit configured to supply a deposition material to a substrate, a substrate holder configured to hold a substrate to receive the deposition material, a shadow mask comprising a frame that includes two opposing arms; and a crossbar configured to be mounted to the two opposing arms. The frame and the crossbar define a plurality of openings that allow the deposition material supplied by the source unit to be deposited on the substrate. A transport mechanism can produce relative movement between the shadow mask and the substrate.

  • Publication number: 20110240461
    Abstract: A method for substrate processing includes producing a magnetic field by a magnetron across the full width of a sputtering surface of a target in a first direction. The magnetron can produce two erosion grooves separated by a distance S on the sputtering surface. The method includes moving the magnetron continuously at a first speed by the distance S in a first segment along a linear travel path. The linear travel path is along a second direction perpendicular to the first direction. The method includes continuously sputtering a material off the sputtering surface and depositing the material on the substrate during the first segment, and moving the magnetron by the distance S in a second segment along the linear travel path at a second speed higher than the first speed without sputtering the material off the sputtering surface or sputtering materials off at significant lower rate.

  • Publication number: 20100012481
    Abstract: A substrate processing system includes a processing chamber that can house a substrate therein; a target comprises a sputtering surface in the processing chamber, wherein the substrate is configured to receive material sputtered off the sputtering surface; a magnetron positioned adjacent to the target, wherein the magnetron can produce two erosion grooves separated by a distance S on the sputtering surface, wherein at least one of the two erosion grooves is characterized by an erosion width W; and a first transport mechanism that can move the magnetron in N steps along a travel path in a first direction. N is an integer. The magnetron can stop at each of the N steps to allow materials to be sputtered off the sputtering surface and to be deposited on the substrate. The N steps have substantially the same step size. The step size is approximately equal to the erosion width W.
