Abstract

PURPOSE:To improve the sensitivity of charge detection without reducing the driving frequency by a method wherein a diffusion layer, with which stepwise potential will be formed, is provided under the transfer electrode located directly in front of an output gate electrode. CONSTITUTION:An N-type diffusion layer 24 is arranged on the region adjacent to the output gate 13 under the transfer electrode 12 located directly in front of an output gate 13. Also, a P-type diffusion layer 25 is arranged on the region adjacent to a transfer electrode 11 under the transfer electrode 12a located directly in front of the output gate 13. As a result, a stepping is generated on the potential to be formed under the transfer electrodes 12 or 12a, and by the lengthening of the electrode length L2 of the transfer electrode 12 or 12a, the gentle-sloped part generating on the potential formed under the transfer electrode 12 can be prevented, and the decrease of driving frequency of the charge transfer device can also be prevented by shortening the time required for completion of the change of potential due to signal charge on a source region 14.
