Thor D. Osborn 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).

  • Component and method for manufacture
    Patent number: 6514789
    Abstract: A component (10) includes a substrate (15), a cap wafer (23), and a protection layer (28) formed over a surface of the cap wafer (23). Together, the protection layer (28) and the cap wafer (23) form a cap structure (39) that is bonded to the substrate (15) via a bonding layer (33). An opening (47) is formed in the cap wafer (23) by etching the cap wafer (23). The protection layer (28) provides protection during etching of the cap wafer (23) for the underlying bonding layer (33) and devices (11,12) formed in the substrate (15).
    Type: Grant
    Filed: October 26, 1999
    Date of Patent: February 4, 2003
    Assignee: Motorola, Inc.
    Inventors: Heidi L. Denton, Henry G. Hughes, Thor D. Osborn, DaXue Xu

  • Tangential flow planar microfabricated fluid filter
    Patent number: 6387290
    Abstract: A microfilter utilizing the principles of tangential flow to prevent clogging, and sloped channel sides to overcome surface tension effects is provided which has feed inlet and exit connected by a feed flow channel; a barrier channel parallel to the feed flow channel, and a filtrate collection channel parallel to the barrier channel so that liquid can flow from the feed flow channel through the barrier channel which is too small to accommodate the particles, into the filtrate collection channel, and from then through a filtrate flow channel to a filtrate exit. Several picoliters of cell-free plasma are recovered from one drop of blood for analysis.
