摘要: A process for depositing oxygen doped semi-insulating polycrystalline silicon (SIPOS) as a passivation layer over the junction of a semiconductor silicon substrate in which the substrate is subjected to an oxygen removal step immediately prior to the creation of the SIPOS layer to thereby prevent the creation of an oxide layer at the interface between the SIPOS and the substrate.
