Definitions

  • the present invention provides a method for forming a thin silicon oxynitride layer with desired channel mobility and drive current.
  • the method according to an embodiment of the present invention includes annealing the silicon oxynitride film with 1 to 100 mTorr oxidizing gas, which can be oxygen, nitrous oxide, or nitric oxide, and annealing the silicon oxynitride film with about 1 slm oxygen.
  • the step of annealing the silicon oxynitride film with 1 to 100 mTorr oxidizing gas is performed at a higher temperature and higher pressure than the step of annealing the silicon oxynitride film with about 1 slm oxygen.
