Fabrication of optical-quality facets vertical to a (001) orientation substrate by selective epitaxial growth
Abstract:
Methods for forming {110} type facets on a (001) oriented substrate of Group III-V compounds and Group IV semiconductors using selective epitaxial growth is provided. The methods include forming a dielectric film on a (100) substrate. The dielectric film can then be patterned to expose a portion of the substrate and to form a substrate-dielectric film boundary substantially parallel to a direction. A {110} type sidewall facet can then be formed by epitaxially growing a semiconductor layer on the exposed portion of the substrate and the dielectric film.
