Abstract: In accordance with the invention a high-k gate dielectric is formed by the steps of first forming a silicon oxide layer over a silicon substrate and then exposing the silicon oxide to a flux of low energy plasma containing metal ions which, when inserted into silicon oxide, form a high-k dielectric material suitable for use as a high-k gate dielectric. In one embodiment, the silicon oxide is exposed to a first plasma containing a first species of metal ions and then to a plasma of another species of metal ions which, when inserted into the silicon oxide with the metal ions in the first plasma, further increase the dielectric constant of the silicon oxide.

Abstract: A computerized system for analyzing information associated with a process unit. A database contains historical information relating to previously compiled information. A secure input receives criteria from a restricted source. A computer mathematically determines a limit based upon the criteria. An open input receives the information associated with the process unit from multiple test locations. A compiler selectively adds to the database of historical information the information. The computer also selects at least a portion of the information based upon selection criteria. In addition, the computer manipulates the selected information based upon manipulation criteria. The manipulated information is compared against the limit. An output indicates a first disposition of the process unit when the manipulated information violates the limit. The output indicates a second disposition of the process unit when the manipulated information does not violate the limit.

Abstract: An interface is provided between a digital signal processor or the like and an output encoder or the like that is capable of counting a system clock of the digital signal processor, generally having a higher clock rate, with respect to at least one or more clocks generally having a lower clock rate. The digital signal processor system clock is passed to the interface that has at least one or more counters. When the accumulation of the system clock reaches a corresponding number of the other clocks, a domain module in the output encoder is triggered, and the corresponding clock counters are reset. The interface may be implemented as a software modeling routine suitable for utilization by a digital signal processor simulator to facilitate complete whole cycle simulation in which multiple clocks having various clock rates may be simulated and compared with a behavior reference. The interface provides cycle-by-cycle comparison of the clocks in an asynchronous domain.

The apparatus includes a circuit for capturing the data read from the memory device relative to the clock strobe signal to produce captured read data, a circuit for latching the captured read data relative to a sample clock signal, and a circuit for measuring a phase difference between the sample clock signal and the clock strobe signal and adjusting a phase of the sample clock signal as a function of the phase difference.

Abstract: A method for communicating on a SCSI bus permits out-of-band addressing and communication for normally non-addressable devices such as SCSI expanders and terminators. The method remaps 18 SCSI data lines for out-of-band operation and manipulates no more than those data lines. Some of the data lines are remapped for purposes of out-of-band signaling and data transfers. Advantageously, manipulation of only the SCSI data lines prevents the possible response of a device on the SCSI network that does not support the out-of-band operations. Accordingly, the disclosed method is backward compatible with existing SCSI networks while allowing implementation of devices having the increased functionality of out-of-band communication.

Abstract: A method for reducing the coupling capacitance between adjacent electrically conductive interconnect lines of an integrated circuit. An electrically conductive layer is deposited and etched to produce electrically conductive interconnect lines having negatively sloped sidewalls. An insulating layer is deposited on the electrically conductive interconnect lines using a directional deposition to create a void between and directly adjacent electrically conductive interconnect lines. The void has a substantially lower dielectric constant than the material of the insulating layer, which reduces the coupling capacitance between adjacent electrically conductive interconnect lines.

Abstract: An aluminum layer formed over an integrated circuit structure is patterned to form a plurality of aluminum metal lines. The patterned aluminum metal lines are then anodized in an acid anodizing bath to form anodized aluminum oxide on the exposed sidewall surfaces of the patterned aluminum. The anodization may be carried out until the anodized aluminum films on horizontally adjacent aluminum metal lines contact one another, or may be stopped prior to this point, leaving a gap between the anodized aluminum oxide films on adjacent aluminum metal lines. This gap may then be either filled with other low k dielectric material or by standard (non-low k) dielectric material. A capping layer of non-porous dielectric material is then formed over the porous anodized aluminum oxide.

Abstract: A method for making a gate in an integrated circuit. A gate layer is formed on a substrate, and a blocking layer is formed on the gate layer. The blocking layer is masked with a photoresist layer, and the photoresist layer is developed to define an exposed gate area. The blocking layer is etched in the gate area to expose the gate layer in the gate area, and the photoresist layer is removed. A metal layer is formed on the blocking layer and on the gate layer in the gate area. The metal layer is selectively reacted with the gate layer in the gate area to form a hard mask over the gate layer in the gate area. The metal layer is removed from the blocking layer. The blocking layer is selectively etched without substantially etching the hard mask in the gate area, to expose the gate layer surrounding the gate area. The exposed gate layer is etched to define a gate in the gate area. The hard mask remains on the gate, and functions as an electrical contact to the gate.

Abstract: An improved multimedia encoder having features advantageous for use in a computer system. These features provide for the reduction of bandwidth and storage requirements, the enhancement of noise immunity, the evening of computational loading, and the use of multimedia drives for general purpose data storage. In one embodiment, the encoder receives image data representing a sequence of video frames and display text data representing a sequence of text fields to be overlaid on the sequence of video frames. The multimedia encoder produces a compressed video frame only for each subsequent video frame which is different from the current video frame. After each video frame is compressed, it becomes the current frame. The multimedia encoder provides error correction encoding to enhance noise immunity, and performs interframe compression using a dynamic search area to even out computational loading.
