Abstract
Methods are disclosed for semiconductor device fabrication in which dopants are selectively implanted into transistor gate structures to counteract or compensate for dopant depletion during subsequent fabrication processing. A patterned implant mask is formed over a semiconductor device, which exposes at least a portion of the gate structure and covers the remaining upper surfaces of the device. Thereafter, dopants are selectively implanted in to the exposed gate structure.
