Patents by Inventor Barry R. Lieberman

Barry R. Lieberman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6646720
    Abstract: A reticle carrier used in semiconductor manufacture. The carrier includes a bottom cover and a top cover having a transparent window. A protective lid may also be included. The box includes ports to allow nitrogen gas to enter and purge the inside. The transparent window is used for inspection and photochemical clean. However, since no material is available which can suitably handle smaller wavelength radiation, the reticle is removed from the carrier when exposure at these wavelengths is required.
    Type: Grant
    Filed: September 21, 2001
    Date of Patent: November 11, 2003
    Assignee: Intel Corporation

  • Patent number: 4694424
    Abstract: A bubble generator for use in a bubble memory device combines a nucleating generator and replicating generator in a unified structure with first and second hairpins disposed at respective first and second regions to define nucleation and replication sites. The conductor layer is configured such that the same polarity of current flow causes magnetic fields of opposite sense at the nucleation and replication sites. The nucleation site is used only to generate the seed bubble required at the replication site. Once the seed bubble is present, the replication site is utilized to produce the data stream. The nucleation and replication sites are preferably spaced apart with a propagation track extending from the former to the latter, and the first and second hairpins are series-connected with the series connection crossing the propagation path. The hairpins are preferably directed oppositely so that when the rotating field is in the right phase for replication, it is 180.degree. out of phase for nucleation.
