The method includes determining at least one unfilled portion of a die prior to a chemical mechanical planarization and filling the at least one unfilled portion with a plurality of dummy structures, a ratio of the dummy structures to a total area of the unfilled portion being in the range of 36 percent and 39 percent. A die formed in accordance with the method may include a plurality of metal levels and a plurality of regions at each metal level, each region having a plurality of dummy structures formed as golden rectangles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dummy structures having a golden ratio and method for forming the same","description":"A method of forming dummy structures in accordance with the golden ratio to reduce dishing and erosion during a chemical mechanical polish.
