Abstract: A field effect transistor (FET) is formed on a silicon substrate, with a nitride gate insulator layer being deposited on the substrate and an oxide gate insulator layer being deposited on the nitride layer to insulate a gate electrode from source and drain regions in the substrate. The gate material is then removed to establish a gate void, and spacers are deposited on the sides of the void such that only a portion of the oxide layer is covered by the spacers. Then, the unshielded portion of the oxide layer is removed, thus establishing a step between the oxide and nitride layers that overlays the source and drain extensions under the gate void to reduce subsequent capacitive coupling and charge carrier tunneling between the gate and the extensions. The spacers are removed and the gate void is refilled with gate electrode material.

Abstract: A method of performing tilted implantation for pocket, halo and source/drain extensions in ULSI dense structures. The method overcomes the process limit, due to shadowing effects, in dense structures, of using large angle tilted implant techniques in ULSI circuits. A gate opening in an oxide layer is defined and partially filled by insertion of nitride spacers to define an actual gate window opening. The small angle tilted implant technique has the equivalent doping effect of large angle tilted implants, and circumvents the maximum angle limit (&thgr;MAX) that occurs in the large angle implant method. The small angle tilted implant technique also automatically provides self alignment of the pocket/halo/extension implant to the gate of the device.

The method includes etching the dielectric layer to form a first structure, depositing an amorphous silicon layer over the first structure, and etching the amorphous silicon layer to form second and third fin structures adjacent first and second side surfaces of the first structure.
