Abstract
A process sequence for forming a semiconductor device utilizes a passivation annealing process using deuterium which enhances immunity to hot carrier effects and extends device lifetime. The process sequence is carried out prior to the introduction of metal conductive films to the device. The process sequence includes a three-step passivation, de-passivation, re-passivation sequence and utilizes a barrier film to encapsulate deuterium molecules in the vicinity of a gate oxide, during the de-passivation operation.
