摘要： A process for modifying sections of a semiconductor includes covering the sections to remain free of doping with a metal oxide, e.g., aluminum oxide. Then, the semiconductor is doped, for example, from the gas phase, in those sections that are not covered by the aluminum oxide. Finally, the aluminum oxide is selectively removed again, for example using hot phosphoric acid. Sections of the semiconductor surface which are formed from silicon, silicon oxide or silicon nitride remain in place on the wafer.

摘要： A gate electrode structure comprises at least one bi-layer, wherein each bi-layer comprises a plating film and a stress amplifier film. The plating film includes a poly-crystalline material. The stress amplifier film determines the crystallization result of the poly-crystalline material, wherein a mechanical stress induced through the plating layer is amplified. Tensile or compressive strain may be induced in a crystalline substrate. Electron or hole mobility may be increased and on-resistance characteristics of a MOS field effect transistor may be improved.
