Abstract:
1. A method, comprising: forming a first material layer over a substrate, said first material layer comprising at least one of a metal and a metal compound; forming a second material layer over said first material layer, said second material layer comprising a semiconductor material; implanting ions of fluorine into said second material layer; implanting ions of a first dopant into said second material layer; implanting ions of a second dopant into a second sub-layer of said second material layer, wherein said second material layer has a first sub-layer that is closer to said substrate than said second sub-layer of said second material layer, and wherein said first dopant and said second dopant are of opposite conductivity type; and after the implantation of the ions of fluorine, the ions of said first dopant and the ions of said second dopant, performing an annealing process activating said first and said second dopant.
