A first topography variation exists between the first region and the second region. A first layer is formed over the first region and over the second region of the wafer. The first layer is patterned. A patterned first layer causes a second topography variation to exist between the first region and the second region. The second topography variation is smoother than the first topography variation. A second layer is formed over the first region and the second region. At least a portion of the second layer is formed over the patterned first layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface topography by forming spacer-like components","description":"A wafer having a first region and a second region is provided.
