Collaborative project PEPSI started
The sub project of University of Konstanz, gettering by porous silicon for an enhancement of charge carrier lifetime of p-type epitaxial silicon wafer, deals with the development of etching processes. Those processes form a porous silicon, that getters in the later reorganisation and epitaxy process different kinds of defects enabling an enhancement in charge carrier lifetime of epitaxially grown silicon wafers to above state of the art levels.
