Abstract:
1. A method for fabricating a Germanium on insulator apparatus, said method comprising: forming a patterned masking layer on a Silicon on insulator (SOI) layer that leaves a portion of the SOI layer exposed; implanting Germanium onto the exposed portion of the SOI layer to form a Silicon-Germanium island; depositing amorphous Germanium over the Silicon-Germanium island and the patterned masking layer; removing the patterned masking layer and the amorphous Germanium that was deposited onto the patterned masking layer to produce a Silicon-Germanium composite stripe; and annealing the Silicon-Germanium composite stripe to crystallize the amorphous Germanium in the Silicon-Germanium composite stripe.
