Abstract
Atomic layer deposition (ALD) or ALD-like deposition processes are used to fabricate dilute nitride III-V semiconductor materials. A first composition of process gases may be caused to flow into a deposition chamber, and a group V element other than nitrogen and one or more group III elements may be adsorbed over the substrate (in atomic or molecular form). Afterward, a second composition of process gases may be caused to flow into the deposition chamber, and N and one or more group III elements may be adsorbed over the substrate in the deposition chamber. An epitaxial layer of dilute nitride III-V semiconductor material may be formed over the substrate in the deposition chamber from the sequentially adsorbed elements.
