    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: 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.

    摘要: In a method for forming patterned ceramic layers, a ceramic material is deposited on a substrate and is subsequently densified by heat treatment, for example. In this case, the initially amorphous material is converted into a crystalline or polycrystalline form. In order that the now crystalline material can be removed again from the substrate, imperfections are produced in the ceramic material, for example by ion implantation. As a result, the etching medium can more easily attack the ceramic material, so that the latter can be removed with a higher etching rate. Through inclined implantation, the method can be performed in a self-aligning manner and the ceramic material can be removed on one side, by way of example, in trenches or deep trench capacitors.

    摘要: The novel trench capacitors have a constant or increased capacitance. Materials for a second electrode region and if appropriate a first electrode region include a metallic material, a metal nitride, or the like, and/or a dielectric region is formed with a material with an increased dielectric constant. An insulation region is formed in the upper wall region of the trench after the first electrode region or the second electrode region has been formed, by selective and local oxidation.
