Abstract:
1. A method of processing a substrate, comprising: a) placing the substrate into a processing chamber; b) introducing a boron containing precursor into the chamber; c) heating the substrate, the boron containing precursor and a nitrogen containing precursor to above 300° C.; d) thermally reacting the boron containing precursor; e) depositing a boron rich film as a homogeneous material on the substrate, the boron rich film having at least 60% boron; f) forming a patterned photo resist layer over the boron rich film; g) etching the boron rich film in a pattern corresponding with the patterned photo resist layer; h) etching the pattern into the substrate; and i) depositing a material in etched portions of the boron rich film.
