  • Interactive task-sensitive assistant
    Patent number: 7890336
    Abstract: A system and method in accordance with the present invention include means for providing interactive assistance for the performance of a set of predefined steps, including selecting the set of predefined steps and automatically generating a step-sensitive grammar for each step. Generating the step-sensitive grammar includes generating a set of navigation commands related to each step and generating a set of rules to recognize potential queries related to each step. A recognizer is configured for determining if a received utterance forms one of the navigation commands or one of the potential queries, within a context of the current step. Form this determination, provided are navigation to a different step if the utterance was a navigation command or a response if the utterance was a query.

  • INTERCONNECTING PROCESS AND METHOD FOR FABRICATING COMPLEX DIELECTRIC BARRIER ALYER
    Publication number: 20070166998
    Abstract: An interconnecting process is described. First, a dielectric layer with a plurality of openings is provided. Then, a metallic layer is formed to fill up the openings. A first dielectric barrier layer is formed to cover the dielectric layer and the metallic layer. Thereafter, a second dielectric barrier layer is formed over the first dielectric barrier layer. The second dielectric barrier layer is used to repair the first dielectric barrier layer and improve the reliability and yield of the process.
