A second region of the second conductivity type is in the substrate, separated and spaced apart from the first region in a substantially vertical direction. A third region of the first conductivity type, heavier in concentration than the substrate, is immediately adjacent to and in contact with the second region, substantially beneath the second region. In a second embodiment, a well of a second conductivity type is provided in the substrate of the first conductivity type. The well has a top surface. A first region of the second conductivity type is near the top surface. A second region of the second conductivity type is in the well, substantially along the bottom of the well.

  • Publication number: 20090079548
    Abstract: A microwave control system is applied to control a working system to execute at least one predetermined assignment, and comprises a microwave control unit, a control card and a passive control unit. A microwave illuminator of the microwave control unit is applied to send a microwave signal. After receiving the microwave signal, the control card reflects a reflection signal to the microwave control unit, wakes up from a first sleep mode to enter a first awake mode, and sends a first control signal to the passive control unit. After the microwave control unit receives the reflection signal, the passive control unit wake up from a second sleep mode to enter a second awake mode, and the passive control unit transmits a second control signal in accordance with the first control signal to the working system, so as to control the working system to execute the predetermined assignment.

  • Patent number: 7496477
    Abstract: A system and method for providing energy-efficient support of continuous aggregate queries in a sensor network by efficiently orchestrating the collection and transmission of data gathered by a collective set of sensors to ensure conformance to a specified QoI bound. To ensure this, the sink communicates a potentially different value of precision range or interval to each individual sensor, the sensor is adapted to only report its samples back to the sink if the sample values fall outside this specified range. An additional way to specify temporally varying precision ranges to an individual sensor or groups of sensors is provided without having to explicitly communicate the precision bounds for these different time instants. Using temporally varying precision ranges permits the exploitation of temporal correlation among the sample values recorded by an individual sensor to further reduce the need for reports from the sensors.

  • Publication number: 20090039410
    Abstract: An improved split gate non-volatile memory cell is made in a substantially single crystalline substrate of a first conductivity type, having a first region of a second conductivity type, a second region of the second conductivity type, with a channel region between the first region and the second region in the substrate. The cell has a select gate above a portion of the channel region, a floating gate over another portion of the channel region, a control gate above the floating gate and an erase gate adjacent to the floating gate. The erase gate has an overhang extending over the floating gate. The ratio of the dimension of the overhang to the dimension of the vertical separation between the floating gate and the erase gate is between approximately 1.0 and 2.5, which improves erase efficiency.

  • Publication number: 20080275578
    Abstract: A data collector control system for semiconductor manufacturing comprises a data collector and a automatic communication port switch control circuit. The control system is placed between an equipment and an equipment automation programming (EAP) system. The data collector processes and transmits communication messages between the equipment and the EAP system while the data collector operates normally. The communication messages between the equipment and the EAP system are transmitted through the control circuit instead of the data collector while the data collector operates abnormally.
