Abstract:
A method for manufacturing a semiconductor device. The method comprises forming a dielectric layer. Forming the dielectric layer includes depositing a silicon oxide layer on a semiconductor substrate, nitridating the silicon oxide layer to form a nitrided silicon oxide layer and incorporating lanthanide atoms into the nitrided silicon oxide layer to form a lanthanide silicon oxynitride layer.
