  • High throughput manufacturing of thin film data recording disks
    Patent number: 5631058
    Abstract: According to the present invention, a blank of an aluminum alloy is partially cut so as to form several disks maintained in the blank by portions of the remaining uncut aluminum. This results in the disks being supported in the blank during formation of the thin films, yet easily separated from the blank into individual disks after the thin films have been deposited. Therefore, multiple disks can be processed during a single manufacturing step.

  • Composite insulator structure
    Patent number: 4601939
    Abstract: A composite insulator structure separating adjacent layers of patterned metal on an LSI chip is disclosed. The bottom layer of sputtered oxide is thicker than the top layer and is preferably planarized. The top layer is conformal plasma nitride so as to uncover unwanted projections on the underlying metal and prevent interlevel shorting between the patterned layers.
