Abstract

Depth-dependent electrical characterization of epitaxial silicon extrinsically gettered with intentionally introduced misfit dislocations is described. To study the effect of buried defects on minority carrier lifetime, a modified Zerbst analysis of the MOS capacitance vs. time response was used to determine generation lifetime as a function of space charge region width. In addition, SEMEBIC imaging at different electron beam energies and EBIC imaging of cross-sections were used to investigate the depth-dependent electrical behavior of these materials.
