| 摘要 |
A method for forming a semiconductor device that includes defining a substrate to include a peripheral section and a core section, masking the peripheral section of the substrate, growing a first dielectric layer over the core section of the substrate, depositing a first polysilicon layer over the first dielectric layer for forming at least one gate structure, growing a first oxide layer over the first polysilicon layer, depositing a nitride layer over the first oxide layer, implanting oxygen ions into the nitride layer, unmasking the peripheral section of the substrate, and growing a second oxide layer over the nitride layer, wherein the growth rate of the second oxide layer is increased due to the implantation of oxygen ions in the nitride layer.
