Abstract

Official abstract text for this publication.

A semiconductor device manufacturing method includes: modifying a surface of a burying recess, of which surface is hydrophobic and which is formed in a dielectric film, to a hydrophilic state by supplying a plasma containing H ions and H radicals or a plasma containing NHx (x being 1, 2 or 3) ions and NHx radicals to the dielectric film formed on a substrate and containing silicon, carbon, hydrogen and oxygen, a bottom portion of the burying recess being exposed with a lower conductive layer; and directly forming an adhesion film formed of a Ru film on the hydrophilic surface of the recess. The method further includes burying copper forming a conductive path in the recess.

First claim

Opening claim text (preview).

What is claimed is: 1. A semiconductor device manufacturing method comprising: modifying a surface of a burying recess formed in a dielectric film by supplying dimethylethylenediamine in a liquid or a gaseous state to the dielectric film formed on a substrate and containing silicon, carbon, hydrogen and oxygen, a bottom portion of the burying recess being exposed with a lower conductive layer, wherein the dimethylethylenediamine is adsorbed onto the surface of the dielectric film…
