发明名称 ROBUST REPLACEMENT GATE INTEGRATION
摘要 A method including forming a dummy gate on a substrate, wherein the dummy gate includes an oxide, forming a pair of dielectric spacers on opposite sides of the dummy gate, and forming an inter-gate region above the substrate and in contact with at least one of the pair of dielectric spacers, the inter-gate region comprising a protective layer on top of a first oxide layer, wherein the protective layer comprises a material resistant to etching techniques designed to remove oxide. The method may further include removing the dummy gate to leave an opening, and forming a gate within the opening.
