Abstract: The invention concerns a non-volatile storage cell having a MOS transistor which, as gate dielectric, comprises a triple dielectric layer (5) consisting of a first silicon oxide layer (51), a silicon nitride layer (52) and a second silicon oxide layer (53). The MOS transistor gate electrode comprises p -doped silicon such that, when a negative voltage is applied to the gate electrode, holes tunnel predominantly from the channel area (4) through the first silicon oxide layer (51) and into the silicon nitride layer (52).

Abstract: The bipolar transistor is produced such that a connection region of its base is provided with a silicide layer, so that a base resistance of the bipolar transistor is small. No silicide layer is produced between an emitter and an emitter contact and between a connection region of a collector and a collector contact. The base is produced by in situ-doped epitaxy in a region in which a first insulating layer is removed by isotropic etching such that the connection region of the base which is arranged on the first insulating layer is undercut. In order to avoid defects of a substrate in which the bipolar transistor is partly produced, isotropic etching is used for the patterning of auxiliary layers, whereby etching is selective with respect to auxiliary layers lying above, which are patterned by anisotropic etching.

Abstract: Production of a trench capacitor comprises preparing a semiconductor substrate having a number of trenches (3-9) with n-doping on its front side; applying a liquid electrolyte to the front side of the substrate; applying an electrical voltage between the rear side of the substrate and the electrolyte so that an electric current with a given current density flows in the layer and mesopores (3-30a) are produced in the trench wall; forming a first electrode in the trench and the mesopores; applying a dielectric (3-34) to the first electrode; and producing as second electrode (3-36) in the dielectric. Preferred Features: The trenches are arranged in a regular two-dimension structure and have the same shape. The surface of the substrate is covered with a horizontal electrically insulating covering layer made from a nitride in the regions between the trenches during the application of the voltage.

Abstract: The invention relates to a bipolar transistor (20) and to a method for producing the same. The inventive bipolar transistor (20) comprises a first layer (30) disposed on a substrate (10) in which layer a collector (31) is provided, a second layer (40) disposed on the first layer (30) and provided with a base recess (41) with a base (42), and at least one further, third layer (50) disposed on the second layer (40) and provided with a feed line (51) for the base (42). Said feed line (51) is in direct contact with the base (42) in a transitional zone (52) and the third layer (50) is provided with an emitter recess (53) with an emitter. The bipolar transmitter is further provided with an undercut (43) that is disposed in the second layer (40) adjoining the base recess (41) between the first (30) and the third (50) layer, said base (42) being at least partially located also in the undercut (43). 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).
