Abstract
PURPOSE: To decrease the input resistance of the control electrode as well as to increase the mutual conductance in order to improve the high frequency properties, by securing a porous property for the area except for the bottom area of the second transmission type diffusion area formed on the first transmission type semiconductor substrate and by providing a diffusion region only at the concavity bottom area changed into a porous insulator film.
