  • 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.

  • Patent number: 9147996
    Abstract: The present invention relates to a laser module comprising several sub-modules (1) arranged side by side along a first axis (10) on a common carrier. Each of said sub-modules (1) comprises a laser area (8) formed of one or several arrays of semiconductor lasers arranged on a surface of the sub-module (1). Laser radiation emitted by each of said semiconductor lasers (2) forms an intensity distribution in a working plane facing said surface of the sub-modules (1). The sub-modules (1) and laser areas (8) are designed and arranged such that the laser areas (8) of adjacent sub-modules (1) partly overlap in a direction perpendicular to said first axis (10). With such a laser module a thin laser line focus can be generated having a homogeneous intensity distribution along the length of the laser line independent on the distance between the module and the working plane. The individual semiconductor lasers (2) may be VCSEL with a rectangularly shaped emission.
