The method of manufacturing a semiconductor device comprises forming a material layer on a substrate, patterning a first semi-global region with a first main pattern and patterning a second semi-global region with a second main pattern, wherein the first main pattern is different than the second main pattern. The method further comprises introducing a first dummy pattern in the first semi-global region so that a first sidewall area surface density of the first main pattern and the first dummy pattern in the first semi-global region and a second sidewall area surface density of the second main pattern in the second semi-global region are substantially a same density."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dummy structures and methods","description":"A semiconductor device and a method of making a semiconductor device are disclosed.
