Abstract

A method for forming a buried metal line in a semiconductor substrate comprises forming, at a position between a pair of semiconductor structures, a metal line trench in the semiconductor substrate at a level below a base of each semiconductor structure of the pair, and forming the metal line in the metal line trench by means of area selective deposition of a metal line material, followed by embedding the pair of semiconductor structures in an insulating layer.
