The middle portion can include a dielectric region having a dielectric composition and a concentrated region of a first material. The first material can be an element of the dielectric composition. The concentrated region can be located at an interface of the middle portion and lower portion. The structure can also include isolation regions in the substrate on opposing sides of the fin. The structure can also include a gate structure over the upper portion of the fin that are exposed from the isolation regions. The gate structure can include a gate dielectric and gate material over the gate dielectric. The structure can also include source/drain regions extending laterally from the upper portion and the middle portion of the fin."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"FETS and methods of forming FETS","description":"A fin structure on a substrate can have a lower portion formed from the substrate, a middle portion, and an upper portion.
