The substrate can be formed of silicon and the substrate layer can be formed of silicon germanium. Above the substrate and under the substrate layer there can be provided a multilayer substructure. The multilayer substructure can include a first layer and a second layer. The first layer can be formed of a first material and the second layer can be formed of second material. A method can include forming a multilayer substructure on a substrate, annealing the multilayer substructure, and forming a substrate layer on the multilayer substructure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin strain relaxed buffers with multilayer film stacks","description":"A semiconductor structure can include a substrate and a substrate layer.
