Claim 0:
1. A method of forming a channel layer for use in a V-NAND device comprising:
providing a substrate, the substrate having an opening;
after providing the substrate, depositing a first material comprising a compound semiconductor material by atomic layer deposition in the opening, wherein the atomic layer deposition of the first material comprises contacting the substrate with a first precursor, wherein the first precursor comprises antimony trimethylsilyl (Sb(SiMe3)3) or an alkylsilyl compound of arsenic; and
filling a remaining portion of the opening with a second material,
wherein the first material comprises at least one of: gallium antimonide (GaSb); gallium arsenide (GaAs); indium antimonide (InSb); indium gallium arsenide (InGaAs); or a combination of aluminum, gallium, or indium with arsenide or antimony.
