  • Patent number: 9917971
    Abstract: A laser scanning device includes a light source, a deflection portion, an image forming lens, and a light source control portion. The light source emits a light beam. The deflection portion causes the light beam emitted from the light source to scan a scanned surface by deflecting the light beam at a predetermined deflection angle. The image forming lens condenses the deflected light beam on the scanned surface, and causes the light beam to be scanned on the scanned surface in a scanning direction at an equal speed. The light source control portion controls the light source to irradiate the light beam to at least one section area among a plurality of section areas sectioned from each other in the scanning direction on the scanned surface, at a plurality of irradiation timings determined based on a position of the at least one section area in the scanning direction.

  • Patent number: 9712712
    Abstract: A method is described for adjusting the focus position of a linear printhead in a digital printing system. A line image is printed including a plurality of variable linewidth lines at different cross-track positions. A digital image capture system is used to capture an image of the printed line image, and a data processing system is used to automatically analyze the captured image to determine linewidth parameters representing linewidths of the plurality of lines. Linewidth progression functions are determined for the lines responsive to the determined linewidths, wherein the linewidth progression functions represent the linewidth parameters as a function of position. The linewidth progression functions are analyzed to determine defocus characteristics of the linear printhead, which are used to adjust the focus position of the linear printhead.

  • Patent number: 9583676
    Abstract: In a wafer bonding process, one or both of two wafer substrates are scored prior to bonding. By creating slots in the substrate, the wafer's characteristics during bonding are similar to that of a thinner wafer, thereby reducing potential warpage due to differences in CTE characteristics associated with each of the wafers. Preferably, the slots are created consistent with the singulation/dicing pattern, so that the slots will not be present in the singulated packages, thereby retaining the structural characteristics of the full-thickness substrates.
