  • Electronic die positioning device and method
    Patent number: 7066788
    Abstract: An autocollimator is relied upon to orient an electronic die such that its frontside is parallel to a polishing surface. The polishing device is configured such that a beam of light that is projected by the autocollimator is able to reflect off of the backside surface of the die. Measurement off of the backside surface allows the die's parallelism relative to the polishing surface to be established without removing the die from the polishing surface and allows the die's orientation to be monitored and adjusted while the frontside is being deprocessed.

  • Sample preparation apparatus and method
    Patent number: 6781232
    Abstract: A apparatus and method for forming windows in semiconductor devices to enable visualization of the circuitry therein while electrically intact. The device is affixed to a table that is oscillated in the X and Y directions while a succession of rotating tools are brought to bear against the surface of the device in the Z direction under a constant force. The force is adjustable so as to allow the tool to float on the surface of the workpiece.

  • Cartilage repair plug
    Publication number: 20040039447
    Abstract: A cartilage plug, which is made from a biocompatible, artificial material, that is used to fill a void in natural cartilage that has been resected due to traumatic injury or chronic disease. Alternatively, the plug may be relied upon to anchor a flowable polymer to subchondral bone. The plug is prefabricatable in any size, shape, and contour and may be utilized either singly or in a plurality to fill any size void for any application. The plug may be formed of a laminated structure to match the physiological requirements of the repair site. A plurality of anchoring elements may share a single upper layer.
