Patent ID: 6914633

Claim:
A charge transfer path comprising: a semiconductor substrate having a surface region of a first conductivity type; a channel region formed in the surface region and extending as a whole along one direction (extension direction) on a surface of said semiconductor substrate, said channel region having a second conductivity type opposite to the first conductivity type and having a stripe plan shape defined by a pair of side edges; an insulating film formed on said semiconductor substrate and covering said channel region; and a plurality of transfer electrodes formed on said insulating film and traversing said channel region, said transfer electrodes having an overlap structure that end portions of adjacent transfer electrodes overlap to define a plurality of border lines of said channel region, and defining a plurality of charge transfer sections partitioned by the border lines in said channel region, wherein each transfer channel region includes a region where a plurality of charge transfer sections are juxtaposed along a direction perpendicular to the extension direction.
