ABSTRACT:
An imaging array of the charge transfer type having improved sensitivity is disclosed. The array includes a plurality of substantially parallel charge transfer channels with channel stops therebetween which extend a distance into a semiconductor body. At least some of the channel stops have blooming drains therein for the removal of excess photogenerated charge. The improvement comprises potential barrier means which constrain electrical charge generated by absorption of light in the body to flow into the channels while preventing the loss of such charge by direct flow to the blooming drains. Potential barrier means include buried barrier regions extending a further distance into the body from those channel stops having blooming drain regions therein.
