The dielectric layer is formed on the conductive structure. A plurality of through holes is formed in the dielectric layer using a metal hard mask, and at least one of the through holes exposes the conductive structure. The conductive features are formed in the through holes. At least one of the conductive features has a bottom surface and at least one sidewall. The bottom surface and the sidewall of the conductive feature intersect to form an interior angle. The interior angles of adjacent two of the conductive features have a difference less than or substantially equal to about 3 degrees."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of manufacturing semiconductor structure comprising plurality of through holes using metal hard mask","description":"A method of manufacturing a semiconductor structure including a conductive structure, a dielectric layer, and a plurality of conductive features is disclosed.
