  • Patent number: 7920343
    Abstract: Micro-electrical-mechanical (MEMS) wafers in which a lens is formed on a micro-electrical-mechanical structure. The micro-electrical-mechanical wafers can comprise a substrate, MEMS structures, and a lens array. A method of forming a micro-electrical-mechanical wafer comprises providing a substrate, forming a micro-electrical-mechanical structure on the substrate, forming a carrier, forming a lens array on the carrier, and transferring the lens array from the carrier onto the micro-electrical-mechanical structure. The lens array is placed above the micro-electrical-mechanical structure.

  • Publication number: 20100123260
    Abstract: A method and stamp for forming lenses on a wafer. The stamp includes a mask arranged on a substrate and aligned with a plurality of lens-shaped cavities. The lens-shaped cavities are used to imprint a plurality of lenses into a curable material. The lenses are cured through the mask using radiation. The lenses are separated from the stamp and the uncured material is removed.

  • Publication number: 20090284837
    Abstract: Methods and apparatus providing a master wafer having standoffs to control a bondline thickness between one wafer produced indirectly from the master wafer and another wafer bonded to the produced wafer. Standoffs may be formed as a single standoff, standoff walls, or as a number of discrete standoffs. The standoffs provide a balanced support base and a uniform spacing between the one wafer and another wafer bonded thereto.
