Abstract :
Results of an investigation of the electrical properties of superficial silicon and epitaxial capping layers grown on multiple-implant/anneal SIMOX and zone melt recrystallization substrates are presented. An unexpected SIMOX conductivity type change (from n to p) was observed in the SIMOX superficial layer, as well as in subsequently grown epi-layers. It is believed that the conductivity-type change is related to the presence of a process-induced acceptor impurity or an impurity (oxygen)-vacancy complex
