Abstract
A charge transfer device has a transfer section for transferring a signal charge along a transfer channel, and a pickup section connected to the transfer section for converting the signal charge received from the transfer section to a voltage signal, both sections being formed on a substrate. The transfer channel is bent generally at a right angle between the transfer section and the pickup section.
Claims5
A charge transfer device having, on a substrate, a transfer section having a plurality of transfer gates for transferring a signal charge along a transfer channel in a specified direction, and a pickup section operatively connected to the transfer gate of a final stage of the transfer section for converting the signal charge received from the transfer section to a voltage signal, characterized in that the transfer channel is bent generally at a right angle between the transfer section and the pickup section;
- wherein the transfer channel is narrowed in a position in which the transfer channel is bent so that a part of the transfer channel located in the pickup section has a width narrower than that of a part thereof located in the transfer section.
