Abstract:
1. A method, comprising: forming one or more elongated semiconductor lines on a layer of electrically insulating material, said layer of electrically insulating material being provided over a substrate comprising a different material than the layer of electrically insulating material, wherein a longitudinal direction of each of said one or more elongated semiconductor lines extends substantially along a horizontal direction that is perpendicular to a thickness direction of said substrate; removing a portion of said layer of electrically insulating material below a central portion of each of said one or more elongated semiconductor lines to expose said substrate; forming a gate insulation layer on said central portion of each of said one or more elongated semiconductor lines and said exposed portion of said substrate; and forming a gate electrode extending all around said central portion of each of said one or more elongated semiconductor lines, said gate insulation layer providing electrical insulation between said elongated semiconductor lines and said gate electrode and between said gate electrode and said exposed portion of said substrate.
