Abstract:
An apparatus for epitaxial growth of a crystal on a first planar surface of a growth substrate, said apparatus comprising:a closed chamber;a source substrate holder disposed inside said closed chamber for holding a source substrate;a growth substrate holder for holding a growth substrate, with a first planar surface of the growth substrate facing and parallel to a second planar surface on the source substrate, to define a gap between the first and second planar surfaces;heating means disposed within said source substrate holder;means for introducing a reaction gas into the gap;linear moving means for moving at least one of said substrates, in a linear direction, during deposition of a reaction product on said growth substrate, to adjust said gap; andplanar moving means for moving at least one of said substrates, during deposition of the reaction product on said growth substrate, to provide planar relative movement between the first and second planar surfaces, said planar relative movement being perpendicular to said linear direction, whereby every point on said second planar surface is brought into confrontation with said first planar surface.
