Varying embodiments of intelligent systems are disclosed that respond to user intent and desires based upon activity that may or may not be expressly directed at the intelligent system. In some embodiments, the intelligent system acquires a depth image of a scene surrounding the system. A scene geometry may be extracted from the depth image and elements of the scene, such as walls, furniture, and humans may be evaluated and monitored. In certain embodiments, user activity in the scene is monitored and analyzed to infer user desires or intent with respect to the system. The interpretation of the user's intent or desire as well as the system's response may be affected by the scene geometry surrounding the user and/or the system. In some embodiments, techniques and systems are disclosed for interpreting express user communication, for example, expressed through fine hand gesture movements. In some embodiments, such gesture movements may be interpreted based on real-time depth information obtained from, for example, optical or non-optical type depth sensors. The depth information may be interpreted in “slices” (three-dimensional regions of space having a relatively small depth) until one or more candidate hand structures are detected. Once detected, each candidate hand structure may be confirmed or rejected based on its own unique physical properties (e.g., shape, size and continuity to an arm structure). Each confirmed hand structure may be submitted to a depth-aware filtering process before its own unique three-dimensional features are quantified into a high-dimensional feature vector. A two-step classification scheme may be applied to the feature vectors to identify a candidate gesture (step 1), and to reject candidate gestures that do not meet a gesture-specific identification operation (step-2). The identified gesture may be used to initiate some action controlled by a computer system. 1. A non-transitory program storage device , readable by a processor and ...

Method for Forming Oxide on Ono Structure

A semiconductor device having a silicon oxide/silicon nitride/silicon oxide (“ONO”) structure is formed by providing a first silicon oxide layer and a silicon nitride layer over a substrate having a memory region and a logic device region; patterning the first silicon oxide layer and the silicon nitride layer to define bottom oxide and silicon nitride portions of partially completed ONO stacks and to expose the substrate in the logic device regions; performing a rapid thermal annealing process in the presence of a radical oxidizing agent to form concurrently a second silicon oxide layer on the exposed surface of the silicon nitride layer and a gate oxide layer over the substrate; and depositing a conductive layer over the completed ONO stacks and the gate oxide. The invention is employed in manufacture of, for example, memory devices having and peripheral logic devices and memory cells including ONO structures. Exposing the patterned silicon nitride to the oxygen radical during the RTO according to the invention significantly reduces the processing time, and reduces the thermal budget. Moreover, because according to the invention the upper surface and the sidewalls of the silicon nitride layer are covered by the top oxide layer, the silicon nitride is not exposed during a subsequent cleaning process. As a result of increased contact area between the polysilicon gate and the top oxide layer, the coupling ratio of the gate is increased.
