  • Publication number: 20050023634
    Abstract: Provided is a method of fabricating a shallow trench isolation (STI) structure having a high aspect ratio and improved insulating properties. The exemplary method includes filling a shallow trench isolation region opening with an undoped polysilicon layer, removing an upper portion of the undoped polysilicon layer to form a second opening having a reduced aspect ratio relative to the original opening and filling the second opening with an insulating material to complete the STI structure. Additional protective layers including silicon oxide, silicon nitride and/or a capping layer may be provided on the sidewalls of the opening before depositing the undoped polysilicon.
