  • Publication number: 20120289061
    Abstract: A hybrid deposition process of CVD and ALD, called NanoLayer Deposition (NLD) is provided. The NLD process is a cyclic sequential deposition process, including introducing a first plurality of precursors to deposit a thin film and introducing a second plurality of precursors to modify the deposited thin film. The deposition using the first set of precursors is not self limiting and is a function of substrate temperature and process time. The second set of precursors modifies the already deposited film characteristics. The second set of precursors can treat the deposited film, including treatments such as modification of film composition and doping or removal of impurities from the deposited film. The second set of precursors can also deposit another layer on the deposited film. The additional layer can react with the existing layer to form a compound layer, or can have minimum reaction to form a nanolaminate film.

  • Publication number: 20120021138
    Abstract: A NanoLayer Deposition (NLD) process for depositing composite films of tertiary, quaternary, pentanary, and hexary stoichiometric films is provided. The inventive deposition process is a cyclic process consisting of a sequence of thin film deposition and treatment steps to obtain a desired film stoichiometry. The deposition steps are not self-limiting as in atomic layer deposition. In one embodiment for depositing a compound oxide film, the deposition process comprises a first deposition, followed by a hydrogen-containing plasma treatment, a second deposition followed by a hydrogen-containing plasma treatment, and then a third deposition followed by a hydrogen-containing plasma and then an oxygen-containing plasma treatment to produce a stoichiometric quaternary film. The cyclic process is repeated until the desired overall film thickness is achieved. The inventive process is used to fabricate high k dielectric films, ferroelectric films, piezoelectric films, and other complex oxides.

  • Publication number: 20100329511
    Abstract: An apparatus and method can effectively detect both hands and hand shape of a user from images input through cameras. A skin image detecting skin regions from one of the input images and a stereoscopic distance image are used. For hand detection, background and noise are eliminated from a combined image of the skin image and the distance image and regions corresponding to actual both hands are detected from effective images having a high probability of hands. For hand shape detection, a non-skin region is eliminated from the skin image based on the stereoscopic distance information, hand shape candidate regions are detected from the remaining region after elimination, and finally a hand shape is determined.

  • Publication number: 20100191683
    Abstract: The present invent ion provides a condensed SVM for high-speed learning using a large amount of training data. A first stage WS selector samples a plurality of training data from a training data DB, selects an optimal training vector xt among the plurality of training data, and outputs it to the WS manager. After the first stage finishes, a second stage WS selector extracts training data one by one from the training data DB and selects training data xt satisfying optimality and outputs it to the WS manager. An SVM optimizer extracts training data closest to the training data xt selected by the first and second stage WS selectors from the WS being managed by the WS manager, and condenses the two first and second training data to one training data when the distance between these is smaller than a predetermined value.
