Claim 0:
1. A method comprising:
providing III-nitride mother crystals;
connecting the III-nitride mother crystals to a first handle substrate, wherein the III-nitride mother crystals on the first handle substrate are separated from each adjacent one of the III-nitride mother crystals by a gap;
providing a second handle substrate;
connecting the III-nitride mother crystals to the second handle substrate;
controlling shape, sizes and positions of the III-nitride mother crystals such that a location and width of the gap between adjacent ones of the III-nitride mother crystals are predetermined to within a tolerance of less than or equal to 5 millimeters; and
selectively separating a layer of the III-nitride mother crystals to form an engineered substrate comprising at least the second handle substrate and a plurality of epitaxial seed layer regions derived from the III-nitride mother crystals.
