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.

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： Charge-trapping regions are arranged beneath lower edges of the gate electrode separate from one another. Source/drain regions are formed in self-aligned manner with respect to the charge-trapping regions by means of a doping process at low energy in order to form shallow junctions laterally extending only a small distance beneath the charge-trapping regions. The self-alignment ensures a large number of program-erase cycles with high effectiveness and good data retention, because the locations of the injections of charge carriers of opposite signs are narrowly and exactly defined.

摘要： The present invention relates to a method for determining the depth of a buried structure in a semiconductor wafer. According to the invention, the layer behavior of the semiconductor wafer which is brought about by the buried structure when the semiconductor wafer is irradiated with electromagnetic radiation in the infrared range and arises as a result of the significantly longer wavelengths of the radiation used in comparison with the lateral dimensions of the buried structure is utilized to determine the depth of the buried structure by spectrometric and/or ellipsometric methods.
