Abstract
A process for forming a portion of a charge coupled device (CCD) is described. More particularly, wells ( ) are formed self-aligned under gate stacks ( ). By forming wells ( ) self-aligned to respective first and second gates ( ) of gate stacks ( ), potential for misalignment is reduced. First gates ( ) of gate stacks ( ) may be coupled together, and second gates ( ) of gate stacks ( ) may be coupled together, and these first and second gates ( ) may be coupled to respective signal sources ( ) to form a two-phase CCD.
