The static and transient latchup performance of conventional and retrograde n-well CMOS technologies is compared. The retrograde n-well structures are shown to have superior latchup immunity, due primarily to the reduced n-well sheet resistance and the greater tolerance to thin p on p+ epitaxial material.
