The method also includes forming a first trench to separate the active region into a first active region and a second active region. The method also includes forming a bit line over the bottom portion of the first trench. The method also includes forming a word line surrounding the first active region and the second active region and over the bit line. The method also includes self-aligned forming a contact over the first active region and the second active region. The method also includes forming a capacitor over the contact."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory structure and method for forming the same","description":"A method for forming a semiconductor memory structure includes forming an isolation structure surrounding an active region in a substrate.
