    Abstract: Capacitors, in particular stacked capacitors for a dynamic memory cell configuration are manufactured by first forming a sequence of layers, which include layers made of a first conductive material alternating with layers made of a second material. The second material can be selectively etched with respect to the first material. Layered structures are formed from the sequence of layers, with the flanks of the layered structures each having a conductive support structure. The layered structures are formed with openings, such as gaps, in which the surface of the layers is exposed. The layers made of the second material are selectively removed with respect to the layers made of the first material. The exposed surface of the layers made of the first material and of the support structure are provided with a capacitor dielectric, onto which a counter-electrode is placed. The capacitor is made by etching p.sup.- -doped polysilicon that is selective to p.sup.+ -doped polysilicon.

    Abstract: A bipolar transistor includes a first layer with a collector. A second layer has a base cutout for a base. A third layer includes a lead for the base. The third layer is formed with an emitter cutout for an emitter. An undercut is formed in the second layer adjoining the base cutout. The base is at least partially located in the undercut. In order to obtain a low transition resistance between the lead and the base, an intermediate layer is provided between the first and the second layer. The intermediate layer is selectively etchable with respect to the second layer. At least in the region of the undercut between the lead and the base, a base connection zone is provided that can be adjusted independent of other production conditions. The intermediate layer is removed in a contact region with the base.

    Abstract: An optical structure includes a substrate having semiconductor material and a grating structure. The grating structure has the property of emitting at least one frequency band so that light having a frequency from that frequency band cannot propagate in the grating structure. The grating structure has a configuration of pores and a defective region. The pores are disposed outside the defective region in a periodic array, and the periodic array is disturbed in the defective region. A surface of the grating structure is provided with a conductive layer at least in the vicinity of the defective region. A method for producing the optical structure is also provided.
