An epitaxial layer is formed on an active fin structure. Metal gate electrodes are formed on the active fin structure. Gate electrode caps are formed on upper surfaces of the metal gate electrodes. Metal gate spacers are formed on sidewalls of the metal gate electrodes. A source/drain electrode is formed on the epitaxial layer. An air spacer region is formed by removing the metal gate electrode caps and the metal gate spacers. An air spacer is formed within the air spacer region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and method of fabricating the same","description":"A method of fabricating a semiconductor device is provided as follows.
