    • A method of and system for cleaning semiconductor wafers minimizes the exposure of the wafers to the air by washing, rinsing and drying the wafers in one cleaning chamber. The system includes a wafer support by which a plurality of wafers can be supported in the cleaning chamber as oriented vertically and spaced from each other, and tubular de-ionized water supply nozzles extending longitudinally in the direction in which the wafers are spaced from each other as disposed to the sides of the wafers. Each de-ionized water supply nozzle has an inner nozzle passageway, and a plurality of sets of nozzle holes extending radially through the main body of the nozzle from the inner nozzle passageway. Each such set of nozzle holes subtends an angle of 80˜100° in a vertical plane and is directed towards a surface of a respective wafer W. During a primary rinse procedure, the de-ionized water is supplied to the de-ionized water spray nozzles, and the liquid in the cleaning chamber is simultaneously discharged from a lower part of the chamber and by being allowed to overflow the chamber. The supplying of the de-ionized water to the de-ionized water spray nozzles and the discharging of the cleaning chamber are carried out in proportions that minimize differences in the etching rate of a wafer across the surface thereof.

    • A wireless modem is mounted to a terminal for wireless communication, and specifically controls an internal drive clock to reduce power consumption in an active mode. The wireless modem includes: a wireless core module for transmitting and receiving a radio signal; a modulator for converting data to be transmitted into a wireless transmission signal and transmitting the converted signal to the wireless core module; a demodulator for converting the signal received from the wireless core module into reception data; a synchronizer for synchronizing the signal received from the wireless core module; and a clock controller for generating a drive clock of each of the modulator, the demodulator, and the synchronizer. A low power clock controller is divided into six main functional blocks of a synchronizer, an analog controller, a modulator, a channel decoder, a demodulator, and a channel encoder, and has a feature that a clock is input only when a main functional block operates. As a result, it is possible to minimize power consumption caused by clock switching when an Orthogonal Frequency Division Multiplexing Access (OFDMA) mobile station modem operates in an active mode through the clock controller.
