    摘要: A technique for more efficiently forming conductive elements, such as conductive layers and electrodes, using chemical vapor deposition. A conductive precursor gas, such as a platinum precursor gas, having organic compounds to improve step coverage is introduced into a chemical vapor deposition chamber. A reactant is also introduced into the chamber that reacts with residue organic compounds on the conductive element so as to remove the organic compounds from the nucleating sites to thereby permit more efficient subsequent chemical vapor deposition of conductive elements.

    摘要: Log entries in a system that produces status or other log data (ASIC verification system, for example) are saved in a circular buffer until a trigger event occurs. Typically, the system operates on a Device Under Test (DUT), but may apply to other systems that simply monitor or gather information. When the trigger occurs, a window of the saved log entries are saved to disk. A level of granularity of the reporting for the log entries is set at any point between low level (cycle based) reporting (recording every event) to high level functional descriptions of the processes or activities performed by the system, DUT, or other item being monitored. Log data from various modules of the system are grouped together to provide a logical view of the recorded log entries.

    摘要: A method of fabricating an integrated circuit on a wafer includes forming a gate electrode stack over a gate dielectric and forming nitride spacers along sidewalls of the gate electrode stack other than along lowermost portions of the sidewalls. Subsequently, a reoxidation process is performed with respect to the gate dielectric. By providing the nitride spacers along exposed surfaces of conductive barrier and metal layers of the word line stack, those surfaces can be passivated, thereby preventing or reducing the conversion of those layers to non-conductive compounds during the reoxidation process. At the same time, the nitride spacers can be formed so that they do not interfere with the subsequent reoxidation of the gate dielectric. An integrated circuit having a gate electrode stack with nitride spacers extending along sidewalls of the gate electrode stack other than along lowermost portions of the sidewalls is also disclosed.
