摘要:
An electronic volume for effecting a control of an impedance circuit in audio devices or the like includes a variable impedance circuit disposed in a signal transmission path and adapted to vary the impedance in accordance with an electronic control signal. A hold/through gate switchable between a hold state and a through state and adapted to permit, when taking the through state, the input signal to pass therethrough in synchronization with a clock signal of a predetermined period and, when taking the hold state, to hold and deliver the input signal as a control signal to the variable impedance circuit, is connected to a control circuit adapted to vary the input signal supplied to the hold/through gate at a predetermined rate at each time of receipt of the hold/through gate, and a rate changing means is provided for changing the rate of variation of the input signal coming through the hold/through gate.

A line-form insulator is formed on a substrate and then the substrate is etched with the insulator used as a mask to form first trenches on both sides of the insulator. Side wall insulators are formed on the side walls of the first trenches, the substrate is etched with the insulator and side wall insulators used as a mask to form second trenches in the bottom of the first trenches. After, the substrate is oxidized with the insulator and side wall insulators used as an anti-oxidation mask to cause oxide regions formed on the adjacent side walls of the second trenches lying on both sides of the substrate to make contact with each other and the insulator and side wall insulators are removed. Then, a fin FET having a semiconductor region as a line-form fin is formed in the substrate.
