The methods may include forming a gate structure on a substrate, forming a first sacrificial pattern and a second sacrificial pattern on opposing sides of the gate structure respectively and partially replacing the first sacrificial pattern with a first insulating pattern such that a portion of the first sacrificial pattern remains in the first insulating pattern and replacing the second sacrificial pattern with a second insulating pattern. The methods may also include replacing at least some of the portion of the first sacrificial pattern that remains in the first insulating pattern with a conductive pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods for fabricating semiconductor devices","description":"Methods of forming a semiconductor device are provided.
