Deep level defects in p/p+ epitaxial silicon were characterized by deep level transient spectroscopy (DLTS). Two dominant deep level defects were found in all samples which have been identified with Fe and CrB pairs. A third deep level defect was found in most of the samples which has tentatively been identified with Ti. The concentrations of these traps were established in a large number of samples as a function of epitaxial growth condition and substrate oxygen level.
