Appl. No.:

09/681402

Inventors:

Paul Hsueh - Concord CA
Shyang Chang - Hacienda CA
Hans Schiesser - Fremont CA
Michael Ma - Union City CA
Jack Hsu - San Jose CA
Abraham C. Ma - Fremont CA

Assignee:

Super Light Wave Corp. - San Jose CA

International Classification:

C23C 1434

US Classification:

20429803, 20429804, 20429811

Abstract:

A vacuum chamber deposits thin films on a substrate by sputtering a target. The beam of atoms or ions from the target is partially blocked by a shadow or adjustable uniformity mask, reducing the deposition rate onto the substrate. The adjustable uniformity mask has several adjustable fingers. The fingers extend or retract to enlarge or reduce the size of the mask. Each finger covers a different annular region or radius of the substrate. The deposition rate at different substrate radii is thus adjustable by the fingers. Several optical beams monitor the film transmittance at different substrate radii. A transmittance profile is continually generated during deposition. As deposition proceeds, radii with a thicker film have their fingers extended to reduce their deposition rate, producing a more uniform film thickness across all radii. Motors extend or retract the individual fingers.

International Classification:

H04J 316

US Classification:

370235, 370392, 370471

Abstract:

A method and apparatus controls network bandwidth between a first node and a second node on a network. A data element transmitted from the first node to the second node is intercepted. The data element comprises a data portion and a header portion including an original window size. The original window size in the header portion of the data element is replaced with a replacement window size, the data portion of the data element remaining unmodified. The data element is then routed to the second node, the header portion of the data element being coupled to the replacement window size.

US Classification:

Abstract:

An improved data access layer (DAL) architecture enables database connection pooling or multiplexing across machine boundaries. Drivers installed at web servers communicate with servers in a DAL. The DAL servers present a virtual database to the web servers, and the DAL servers in turn open connections to a set of physical databases. DAL servers are able to recycle connections that are no longer needed, or to move available connections from one DAL server to another, so as to provide improved efficiency in connection management, burst management, and peak load management. Scalability is thereby improved, and more efficient use of system resources is facilitated.
