Abstract

PURPOSE:To facilitate an easy formation of IC with the same chip for the filter using the charge transfer element by using one end of the charge transfer element region as the signal input part and the other end as the signal output part each and then connecting the electrode formed on the impurity layer via an insulator to the switching element. CONSTITUTION:Transfer charge element part 7, 8 and 9 are provided on the surface of the semiconductor substrate, and then coupling diffusion layer 2 and 3 are added to give the electric connection between parts 7, 8 and 9, along with input part diffusion layer 1 to compose the signal input/output part plus output part diffusion layer 4 to compose the output part respectively. In addition, insulator film 15 is provided on layer 23, and electrode 5 and 6 connected to switching element 10 and 11 independently are provided via film 15. At the same time, layer 2 and 3 plus electrode 5 and 6 are formed so that plural units of the capacity value may be secured between them, and element 10 and 11 are connected to electrode 5 and 6 so that the capacity value may be controlled independently.
