The semiconductor connection structure includes a substrate with an array area, a first trench, a metal line, a work function layer and a contact structure. The array area includes a central region and an edge region surrounding the central region. The first trench is formed in the substrate and extends from the central region to the edge region along a first direction. The first trench has a first portion in the central region and a wider second portion in the edge region. The metal line and the work function layer are formed in the first trench. The contact structure is formed in the first trench within the edge region. The contact structure is located on the metal line and in direct contact with the metal line. The bottom portion of the contact structure is surrounded by the work function layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor connection structure and method for manufacturing the same","description":"A semiconductor connection structure and its manufacturing method are provided.
