The trench isolation region comprises laterally-opposing laterally-outermost first regions which comprise a first material and a second region laterally-inward of the first regions. The second region comprises a second material of different composition from that of the first material. A diffusion region is in the uppermost portion of the semiconductive material directly against a sidewall of one of the first regions. Insulator material is above the trench isolation region and the diffusion region. An elevationally-elongated conductive via is in the insulator material and extends to the diffusion region and the trench isolation region. The conductive via laterally overlaps the diffusion region and the one first region. The conductive via is directly against a top surface of the diffusion region, is directly against an upper portion of a sidewall of the diffusion region, and is directly against a laterally-outer sidewall of the second material of the second region of the trench isolation material. Other embodiments, including method, are disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Construction of integrated circuitry and a method of forming an elevationally-elongated conductive via to a diffusion region in semiconductive material","description":"A construction of integrated circuitry comprises a trench isolation region in semiconductive material.
