Abstract

PURPOSE: To obtain a digital capactitor by changing the area of the superposed portions of the electrodes provided on conductivity type regions via insulation films in a lengthwise direction to stepwise change capacity values and at the same time stepwise changing the drains and gates of switching FETs.
