  • Patent number: 8319839
    Abstract: An optical image system includes an image pickup module, a swinging mechanism, a first swinging calibration element and a second swinging calibration element. When the optical image system is tilted because of handshaking, the image pickup module is swung by the swinging mechanism. At the same time, the first swinging calibration element and the second swinging calibration element detect whether the image pickup module is swung to an ideal position where the handshaking problem is eliminated.

  • Patent number: 8236484
    Abstract: As the critical dimensions of liftoff patterns grow smaller, it becomes increasingly more difficult to make liftoff resists that have the required resolution. This problem has been overcome by use of a combination of ion beam processing and ozone slimming to form lift-off patterns with undercuts from a single layer of photoresist. The ion beam process serves to harden the top portion of the resist while the ozone is used to oxidize and erode the lower portion resist sidewall to form the undercut.
