Abstract:
A method of manufacturing a semiconductor device comprising:providing a wafer;providing a chamber with a filament having a first material located at a first end of the filament and providing a different material at a second end of the filament, the second end opposite the first end of the filament;creating ions in the chamber;electrically biasing the first material to a negative potential relative to all portions of the filament to attract the ions;electrically biasing the different material to a positive potential relative to the first material such that the ions are more attracted to the first material than the different material;using the ions to generate a sputtered material from the first material in the chamber wherein the ions are devoid of reactive ion etching the first material;creating other ions from the sputtered material in the chamber;extracting the other ions out of the chamber; andimplanting the other ions into the wafer.
