For instance, a construction may have a material over a plurality of electrically conductive lines. A plurality of annular features may be formed over the material, with the annular features crossing the lines. A patterned mask may be formed over the annular features, with the patterned mask leaving segments of the annular features exposed through a window in the patterned mask. The exposed segments of the annular features may define a plurality of openings, and such openings may be transferred into the material to form openings extending to the electrically conductive lines."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of patterning a material","description":"Some embodiments include methods of forming openings.
