Title New Approaches for Passivation of Crystalline and Amorphous Silicon.
Publication Date Sep 2012
Media Count 3p
Personal Author N/A
Abstract New approaches of passivating crystalline, multicrystalline, and amorphous silicon will be explored. These will include the use of aqueous solution of KCN and a proprietary composition formulated by Mallinckrodt Baker, Inc. The surface passivation will be compared with that provided by an iodine-ethanol solution, and bulk passivation will be compared with that of H-passivation obtained by silicon nitride, in a fire-through process. This work determined that KCN-based aqueous solution provided a good passivation if the wafer has a thin oxide layer. In the absence of the oxide, KCN passivation was not effective.
