Abstract: A system is disclosed that provides a goal based learning system utilizing a rule based expert training system to provide a cognitive educational experience. The system provides the user with a simulated environment that presents a business opportunity to understand and solve optimally. Mistakes are noted and remedial educational material presented dynamically to build the necessary skills that a user requires for success in the business endeavor. The system utilizes an artificial intelligence engine driving individualized and dynamic feedback with synchronized video and graphics used to simulate real-world environment and interactions. Multiple "correct" answers are integrated into the learning system to allow individualized learning experiences in which navigation through the system is at a pace controlled by the learner.

Abstract: A trench isolation structure for a semiconductor is provided including an isolation ring and an isolation path. The isolation ring surrounds active semiconductor areas and is bordered on the outside by inactive semiconductor area. The isolation path extends from the isolation ring through the inactive semiconductor area. A first level conductor on the isolation path electrically connects or capacitively couples a device in the active semiconductor area to a location on the substrate outside the isolation ring. The isolation path has a configuration derived from the layout of the conductor.

Abstract: A method is presented for controlled formation of microcavities for various semiconductor and micro-machine applications. The method involves the steps of defining a void in a support structure, sealing the void with a resilient gas-permeable material such that a chamber is formed, diffusing gas into the chamber through the gas permeable material to create a pressurized chamber, and then allowing expansion of the pressurized chamber within the resilient material, thereby creating an enlarged cavity. The applications set forth include the production of large capacitors, field isolation structures, tubular sensors for chromatography, pressure sensors, and cooling channels for integrated circuits.

Abstract: A process for making a crackstop on a semiconductor device is disclosed. The process involves creating and metallizing a groove surrounding the active region on a chip at the same time as other functional metallization is occurring, and then selectively etching out the metal in the groove after final passivation. In various embodiments the groove passes through the surface dielectric or the semiconductor substrate. In one embodiment the groove is replaced by hollow metal rings that can be stacked through multiple dielectric layers.
