Abstract

PURPOSE:To secure performance of various types of function perations through the simple structure and the driving circuit by distributing two gate electrodes close to each other to carry out the charge coupling between the both electrodes and then securing the uneven effective resistance per unit length of one gate electrode. CONSTITUTION:First gate electrode 1 and high resistance gate electrode 2 are provided close to each other on semiconductor substrate A via the insulator film, and part 3 is provided to receive the accumulated charge at the active region of substrate A under electrode 2. Then first transfer electrode 31 is provided at part 3, and source S of charge transfer device CTD is formed on electrode 1. At the same time, terminal 4 is provided to apply the negative bias to source S along with terminal 5 to apply the DC voltage to electrode 1 plus terminal 6 and 7 to apply the DC voltage to electrode 2. Then terminal 6 and 7 are connected to ohmic contact 2a and 2b to secure the uneven resistance value along the fixed direction and per unit length. The uneven well is formed on the surface layer of substrate A, and the charge accumulated into the well is controlled by the voltage to be applied to electrode 1 to be then transferred to part 3.
