    Abstract: A substrate made from silicon has a first region and a second region. Through pores are formed in the first region. Pores that do not traverse the substrate are provided in the second region. The production of the work piece is performed with the aid of electrochemical etching of the pores. The entire surface of the substrate is covered with a mask layer that is structured photolithographically on the rear of the substrate. The bottoms of the pores in the second region are etched clear, preferably using KOH.

    Abstract: The invention concerns a semiconductor structure comprising a substrate (10), an insulating layer (14) arranged on one surface of the substrate (10), a layer (18) for components arranged on one surface (16) of the insulating layer (14) opposite the substrate (10), a semiconductor component (30a, 30b) arranged in the layer (18) for components and zone designed for capacitively uncoupling said semiconductor component (30a, 30b) relative to the substrate (10), said zone being formed by a space charge zone (96) formed in a region of the substrate (10) adjacent to the insulating layer (14).

    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.
