Patent ID: 7432120

Claim:
A method for realizing a hosting structure of nanometric elements comprising: depositing on an upper surface of an insulating substrate of a first material, a block-seed having a side wall perpendicular to said upper surface; depositing on a portion of said surface and of said block-seed a first layer of first thickness of a second material; anisotropically etching said first layer to provide a spacer-seed adjacent to at least one portion of said side wall of said block-seed; repeating n times, with n≧2, a step comprising a deposition on at least one portion of said substrate of a layer of a thickness of a material followed by an anisotropic etching of said layer with realization of at least one relative spacer, said deposited material being different for each pair of consecutive depositions, said n steps defining at least one multilayer body comprising n spacers made of at least two different materials and said at least one spacer-seed; and selectively etching said multilayer body to remove a fraction of said spacers for realizing at least one plurality of nanometric hosting seats such that said structure is suitable for hosting in said at least one plurality of hosting seats a plurality of nanometric elements, a remaining fraction of said spacers realizing contact terminals for said elements.
