    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: 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 method for providing interlocking strained silicon on a silicon substrate, comprises providing a mask on a surface of the substrate. The mask comprises a first plurality of openings corresponding to a first plurality of holes to be etched and comprises a second plurality of openings corresponding to a second plurality of holes to be etched. The surface of the substrate is etched through the mask to form the first and second pluralities of holes. A first strain type material is deposited into the first plurality of holes to form a plurality of first strain type portions. A plurality of second strain type portions are formed at the second plurality of holes.
