ABSTRACT:
A charge-coupled device (CCD) of the two-phase type is disclosed. The CCD comprises two polysilicon levels which are electrically connected to form one clock phase. In order to provide a CCD of improved transfer efficiency, two implanted regions of different dopant levels are provided under each polysilicon level. When the CCD is clocked, a four-tier potential profile is produced.
