Abstract:
A method of manufacturing a semiconductor device comprising forming a gate oxide layer over a substrate subjecting the gate oxide layer to a first nitridation process, subjecting the gate oxide layer to a first anneal process after the first nitridation process, subjecting the gate oxide layer to a second nitridation process after the first anneal process, subjecting the gate oxide layer to a second anneal process after the second nitridation process, and forming a gate electrode over the gate oxide.
