The method may include: removing a dummy gate from over a set of fins to form an opening in a dielectric layer exposing the set of fins, each fin in the set of fins being substantially separated from an adjacent fin in the set of fins via an dielectric; forming a protective cap layer within the opening over the exposed set of fins; removing a portion of the dielectric on each side of each fin in the set of fins; undercutting each fin by removing a portion of each fin in the set of fins to create a notch disposed under the protective cap layer; substantially filling each notch with an oxide; forming a gate dielectric over each fin in the set of fins; and forming a gate conductor over the gate dielectric, thereby forming the replacement gate structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"FINFET having notched fins and method of forming same","description":"One aspect of the disclosure provides for a method of forming a replacement gate structure.
