    摘要: A process for forming a silicon nitride layer on a gate oxide film as part of formation of a gate structure in a semiconductor device includes: forming a layer of silicon nitride on top of a gate oxide film on a semiconductor substrate by a nitridation process, heating the semiconductor substrate in an annealing chamber, exposing the semiconductor substrate to N2 in the annealing chamber, and exposing the semiconductor substrate to a mixture of N2 and N2O in the annealing chamber.
