    Abstract: A capacitive touch apparatus includes a first touch unit, a first voltage difference retrieving unit, a first feedback signal generating unit, and a control unit. The first touch unit has a touch substrate and a first conductive layer. The first voltage difference retrieving unit is electrically connected with the first conductive layer and outputs a first voltage signal and a second voltage signal. The first feedback signal generating unit outputs a first feedback signal according to the variation of the voltage difference between the first voltage signal and the second voltage signal. The control unit receives the first feedback signal for computing the touch position and outputs a power signal to the first voltage difference retrieving unit. Hence, the capacitive touch apparatus improves the sensing speed and reduces the manufacturing cost by the simple circuit design.

  • Publication number: 20120115329
    Abstract: Methods and apparatuses for filling high aspect ratio features with tungsten-containing materials in a substantially void-free manner are provided. In certain embodiments, the method involves depositing an initial layer of a tungsten-containing material followed by selectively removing a portion of the initial layer to form a remaining layer, which is differentially passivated along the depth of the high-aspect ration feature. In certain embodiments, the remaining layer is more passivated near the feature opening than inside the feature. The method may proceed with depositing an additional layer of the same or other material over the remaining layer. The deposition rate during this later deposition operation is slower near the feature opening than inside the features due to the differential passivation of the remaining layer. This deposition variation, in turn, may aid in preventing premature closing of the feature and facilitate filling of the feature in a substantially void free manner.

    Abstract: A control method of the magnetic actuator system includes the following steps. A first initial orientation step is to move a magnetic actuator to a first position in accordance with a first position signal, and generate a first position sense signal by a position sensor. A second initial orientation step is to move the magnetic actuator to a second position in accordance with a second position signal, and generate a second position sense signal by the position sensor. An orientation step is to perform an interpolation in accordance with the above signals and a target position signal to obtain a target position sense signal. A moving step is to move the magnetic actuator to an actual position in accordance with the target position signal, and output an actual position sense signal by the position sensor. An adjustment step is to move the magnetic actuator to a target position in accordance with the target position sense signal and the actual position sense signal.

  • Publication number: 20120009785
    Abstract: Methods and apparatuses for filling high aspect ratio features with tungsten-containing materials are provided. The method involves providing a partially fabricated semiconductor substrate and depositing a tungsten-containing layer on the substrate surface to partially fill one or more high aspect ratio features. The method continues with selective removal of a portion of the deposited layer such that more material is removed near the feature opening than inside the feature. In certain embodiments, removal may be performed at mass-transport limited conditions with less etchant available inside the feature than near its opening. Etchant species are activated before being introduced into the processing chamber and/or while inside the chamber. In specific embodiments, recombination of the activated species is substantially limited and/or controlled during removal, e.g., operation is performed at less than about 250° C. and/or less than about 5 Torr.
