Patent number: 6735677Abstract: A unique memory access system and method to handle memory access requests to a memory shared by multiple independent data access devices (“IDADs”). More particularly, the present invention relates to a method and system that allows IDADs to efficiently execute memory access requests without having to wait for the shared memory to be available. In addition, the IDADs do not have to be designed to observe the specific memory protocol. The memory access requests from the IDADs are accepted by access request logic which then queues the requests. Memory access logic then executes the requests from the queue when the shared memory is available. The memory access logic places data obtained from read requests in a read buffer for the IDADs to access when convenient.Type: GrantFiled: April 30, 2001Date of Patent: May 11, 2004Assignee: LSI Logic CorporationInventor: Charles H. Stewart

Patent number: 6733829Abstract: A deposition ring which has a cut out on its interior circumferential edge. The deposition ring is configured to contact an edge of an electrostatic chuck and shield at least a portion of the electrostatic chuck during a deposition process wherein material is deposited onto an item, such as a semiconductor wafer, which is disposed on the electrostatic chuck. The interior circumferential edge of the deposition ring includes a surface portion which is configured to engage the edge of the electrostatic chuck, and includes the cut out portion which is configured to be spaced away and not contact the edge of the electrostatic chuck during the deposition process. As such, the deposition ring does not tend to bind with the electrostatic chuck during the deposition process.Type: GrantFiled: March 19, 2002Date of Patent: May 11, 2004Assignee: LSI Logic CorporationInventors: Dave Stacey, Jonathan Allinger, Allan Vescovi

Publication number: 20040086430Abstract: An apparatus for reducing residual oxygen content from a processing chamber of an atmospheric reactor after the processing chamber of the atmospheric reactor has been exposed to an oxygen environment. The processing chamber of the atmospheric reactor has an inert gas purge, including an inert gas source, for reducing a residual oxygen level within the processing chamber of the atmospheric reactor at a rate of reduction. A venturi vacuum system is enabled by the inert gas source. The venturi vacuum system draws a vacuum on the processing chamber of the atmospheric reactor and supplements the inert gas purge, thereby accelerating the rate at which the residual oxygen level is reduced within the processing chamber of the atmospheric reactor. In this manner, the vacuum created by the venturi vacuum system increases the efficiency of the inert gas purge by reducing by some moderate degree the pressure within the processing chamber of the atmospheric reactor.Type: ApplicationFiled: August 13, 2003Publication date: May 6, 2004Applicant: LSI Logic CorporationInventors: Mark I. Mayeda, Steven E. Reder, Richard Gimmi, Matthew R. Trattles

Patent number: 6732201Abstract: A system has a plurality of enclosures. Each enclosure has two enclosure services modules. Each enclosure services module has an IN port and an EXPANSION port. Each enclosure services module is able to determine the data rate of incoming data and check the validity of this data. If the data rate is other than what the enclosure services module is set for, the data rate of the enclosure services module is changed to that of the incoming data. In the system, there are a disk array controller having a first channel and a second channel. The first channel is formed in sequence from a disk array controller to a first enclosure services module of a first enclosure and between first enclosure services modules of successive enclosures to a last enclosure. The second channel is formed in reverse sequence from the disk array controller to the second enclosure services module of the last enclosure and between second enclosure services modules of successive enclosures to the first enclosure.Type: GrantFiled: December 17, 2001Date of Patent: May 4, 2004Assignee: LSI Logic CorporationInventors: Jeremy D.

Patent number: 6727177Abstract: Embodiments of the invention include a method for forming a copper interconnect having a bi-layer copper barrier layer. The method involves providing a substrate having an insulating layer with an opening therein configured to receive an inlaid conducting structure. A copper seed layer is formed on the insulating layer and in the opening. The seed layer is implanted with barrier material ions to form an implanted seed layer. Upon the implanted seed layer is formed a bulk copper-containing layer. The substrate is then annealed so that barrier material ions migrate through the seed layer to an interface between the seed layer and the insulating layer to form a final barrier layer. The barrier material can include palladium, chromium, tantalum, magnesium, and molybdenum.Type: GrantFiled: October 18, 2001Date of Patent: April 27, 2004Assignee: LSI Logic CorporationInventors: Wilbur G.

Patent number: 6728477Abstract: A DVD player or computer with a DVD drive simultaneously presents multiple angles of video on a display. DVD standards provide for formatting and storing video that was filmed from more than one angle. Desired angles are selected, and the DVD player multiplexes between each angle of the playback to decode video frames for each selected angle. The frames for each angle being played back are filtered down to a size that fits into a fragment of the display. Each of the filtered frames are assembled into a single frame that can be presented on the display to simultaneously playback each angle.Type: GrantFiled: December 28, 1999Date of Patent: April 27, 2004Assignee: LSI Logic CorporationInventor: Daniel Watkins

Patent number: 6728910Abstract: A method is presented for self-test and self-repair of a semiconductor memory device. A single built-in self-test (BIST) engine with an extended address range is used to test the entirety of memory (i.e., both redundant and accessible memory portions) as a single array, preferably using a checkerboard bit pattern. An embodiment of the method comprises two stages. In the first stage, faulty rows in each memory portion are identified and their addresses recorded. Known-bad rows in accessible memory are then replaced by known-good redundant rows, and the resulting repaired memory is retested in a second stage. During the second stage, repair of the accessible memory portion is verified, while defects among the redundant portion are ignored. Compared to existing methods, the new method is believed to simplify the interface between the BIST and the built-in self-repair (BISR) circuitry, reduce the overall size of test and repair circuitry, and provide improved test coverage.Type: GrantFiled: September 20, 2000Date of Patent: April 27, 2004Assignee: LSI Logic CorporationInventor: Johnnie A.
