The defect density of planar silicon on insulator (SOI) islands fabric
ated by epitaxial lateral overgrowth (ELO) are given. While the effect
s of the annealing on the defect density were mixed, low defect densit
y SOI can be grown by this method where 96% of the islands were defect
free. With better process procedures the defect density can be lower
than the reported 1x10(3)/cm(2).
