The method includes forming a gate stack over a semiconductor substrate and forming a spacer element over a sidewall of the gate stack. The method also includes forming a dielectric layer over the semiconductor substrate to surround the gate stack and the spacer element and replacing the gate stack with a metal gate stack. The method further includes forming a protection element over the metal gate stack and forming a conductive contact partially surrounded by the dielectric layer. A portion of the conductive contact is formed directly above a portion of the protection element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for forming semiconductor device with gate stack","description":"A method for forming semiconductor device structure is provided.
