Technique for filling high aspect ratio, narrow structures with multiple metal layers and associated configurations

Abstract

Embodiments of the present disclosure describe techniques for filling a high aspect ratio, narrow structure with multiple metal layers and associated configurations. In one embodiment, an apparatus includes a transistor structure comprising a semiconductor material, a dielectric material having a recess defined over the transistor structure, the recess having a height in a first direction, an electrode terminal disposed in the recess and coupled with the transistor structure, wherein a first portion of the electrode terminal comprises a first metal in direct contact with the transistor structure and a second portion of the electrode terminal comprises a second metal disposed on the first portion and wherein an interface between the first portion and the second portion is planar and extends across the recess in a second direction that is substantially perpendicular to the first direction. Other embodiments may be described and/or claimed.
