    摘要： A polishing method and polishing apparatus able to easily flatten an initial unevenness with an excellent efficiency of removal of excess copper film and suppress damage to a lower interlayer insulation film, and a plating method and plating apparatus able to deposit a flat copper film. The polishing method comprises the steps of measuring thickness equivalent data of a film on a wafer, making a cathode member smaller than the surface face a region thereof, interposing an electrolytic solution between the surface and the cathode member, applying a voltage using the cathode member as a cathode and the film an anode, performing electrolytic polishing by electrolytic elution or anodic oxidation and chelation and removal of a chelate film in the same region preferentially from projecting portions of the film until removing the target amount of film obtained from the thickness equivalent data, and repeating steps of moving the cathode member to another region to flattening the regions over the entire surface. Further, plating is performed by a reverse reaction of the above.

    摘要： An AGC circuit according to the present invention comprises: a gain controller, having a variable gain, for amplifying an input signal at a predetermined gain and generating an output signal, and for varying the gain; a comparison circuit for comparing an amplitude of the input signal or of the output signal with a predetermined reference level, and for generating a control signal that goes to a first level when the amplitude is smaller than the reference level, and that goes to a second level when the amplitude is greater than the reference level; and a duty ratio detector for supplying the control signal generated by the comparison circuit, and for generating control code in accordance with a duty ratio of the control signal, wherein the gain of the gain controller is varied by using the control code, and so adjusted that the duty ratio of the control signal is maintained to be a predetermined value. When the amplitude of the input signal or the output signal is increased, a period during which the amplitude exceeds the reference level is also extended. By utilizing this phenomenon, a gain is varied so as to maintain a control signal duty ratio of 50%, for example, so that the amplitude of the output signal is amplified to a desired value, which is maintained.

    摘要： A compander circuit includes first and second volume controllers, a comparator, a counter and a control part. The comparator compares a compared voltage with a rectified and smoothed signal of an input signal of the compander circuit or an output signal of the first volume controller receiving the input signal, the compared voltage being an output signal of the second volume controller. The counter executes a count operation on an output signal of the comparator in synchronism with a clock signal and controls gains of the first and second volume controllers on the basis of a counter value of the counter. The control part controls a frequency of the clock signal applied to the counter by a predetermined control signal.
