    • The invention relates to a bipolar transistor (20) and to a method for producing the same. In order to obtain an as low a transition resistance as possible between the feed line (51) and the base (42), an intermediate layer (70) is provided between the first (30) and the second (40) layer, said intermediate layer (70) being selectively etchable to the second layer (40). At least in the zone of the undercut (43) between the feed line (51) and the base (42) a base connection zone (45) is provided that can be adjusted independent of other production conditions. The inventive transistor is further characterized in that the intermediate layer (70) is removed in the contact zone (46) with the base (42).

    • The inventive integrated circuit comprises at least one first component with a structure to which defects may be adjacent and a second component with at least one p-n junction (Ü'), said components being situated next to each other in a substrate (1) whose defects extend in a defect plane (d) at least in sections. The crystal orientation of the substrate (1) in relation to the first component and the second component is chosen with the aim of keeping the defects on the surfaces without them intersecting the p-n junction (Ü'), in order to prevent undesirable leakage currents through the p-n junction (Ü'). The integrated circuit is especially a DRAM cell arrangement with extended retention time. The inventive integrated circuit is produced by mounting photo-resist masks of a known layout on the starting wafer, the masks being rotated in relation to a known starting wafer. Alternatively, photo-resist masks of a known layout can be mounted on a starting wafer in a conventional manner, the output wafer having a marking showing the course of the defect plane (d).

    • The invention relates to a method for producing trench capacitors having trenches (3-9) with mesopores (3-12). These trench capacitors are suited both for discrete capacitors and for integrated semiconductor memories. The mesopores significantly increase the surface for electrodes for the trench capacitors and thereby the capacitance of the trench capacitors. According to the invention, the mesopores, which are small channels similar to those made by woodworms and which have diameters ranging from 2 to 50 nm, are electrochemically produced. This method enables the production of capacitances with a high capacitance-to-volume ratio. The invention is additionally advantageous in that the growth of the mesopores stops once the mesopores reach a minimal distance from another mesopore or from adjacent trenches (self-passivation). As a result, the formation of short circuits between two adjacent mesopores can be prevented in a self-regulated manner. The invention also relates to a semiconductor component comprising at least one trench capacitor on the front side of a semiconductor substrate, which can be produced using the inventive method.
