    摘要: A method for using a film formation apparatus for a semiconductor process to form a thin film on a target substrate while supplying a film formation reactive gas from a first nozzle inside a reaction chamber includes performing a cleaning process to remove a by-product film deposited inside the reaction chamber and the first nozzle, in a state where the reaction chamber does not accommodate the target substrate. The cleaning process includes, in order, an etching step of supplying a cleaning reactive gas for etching the by-product film into the reaction chamber, and activating the cleaning reactive gas, thereby etching the by-product film, and an exhaust step of stopping supply of the cleaning reactive gas and exhausting gas from inside the reaction chamber. The etching step is arranged to use conditions that cause the cleaning reactive gas supplied in the reaction chamber to flow into the first nozzle.

    摘要: A single transistor device is configured of a plurality of transistor cells divided and arranged in a plurality of blocks. Corresponding to the blocks a plurality of bias current supply circuits are arranged, respectively, to supply the blocks with individual bias currents, respectively. The bias current supply circuits each have a transistor with a bias condition set to decrease its ability to drive current as the corresponding bias current increases. Thus a negative feedback can be given to an increase in bias current attributed to thermal unevenness.

    摘要: In an RF front end portion for processing a radio-frequency signal in a portable telephone, a low pass filter allowing passing of only a signal in a frequency band lower than a radio-frequency signal component band is arranged between a circuit processing a high power signal and a control circuit controlling operation of the radio-frequency signal processing circuit. The radio-frequency signal processing circuit is a transmission/reception multiplexing circuit transferring a transmission signal of the portable telephone to an antenna or receiving a reception signal from the antenna, and the control circuit is a transmission/reception control circuit determining an operation mode of the transmission/reception multiplexing switch. Alternatively, the radio-frequency signal processing circuit includes a power amplifier amplifying a signal to be transmitted, and a gate voltage control circuit generating gate bias voltage controlling a gain of the power amplifier. The influence of a radio-frequency leakage component leaking from a gate of the field effect transistor can be suppressed. In the case of the transmission/reception multiplexing switch, handing power can be improved, and an increase in power consumption and occupied area of the control circuit can be suppressed. In the case of the power amplifier, the gate bias voltage can be held stably, and the power amplification can be performed accurately. In the portable telephone, the RF front end portion processing the radio-frequency signal can be provided in a chip occupying a small area.
