Abstract: Described herein are techniques for forming an epitaxial III-V layer on a substrate. In a pre-clean chamber, a native oxygen layer may be replaced with a passivation layer by treating the substrate with a hydrogen plasma (or products of a plasma decomposition). In a deposition chamber, the temperature of the substrate may be elevated to a temperature less than 700° C. While the substrate temperature is elevated, a group V precursor may be flowed into the deposition chamber in order to transform the hydrogen terminated (Si—H) surface of the passivation layer into an Arsenic terminated (Si—As) surface. After the substrate has been cooled, a group III precursor and the group V precursor may be flowed in order to form a nucleation layer. Finally, at an elevated temperature, the group III precursor and group V precursor may be flowed in order to form a bulk III-V layer.
