    Abstract: The invention relates to a method for producing structures and, in particular, wires on the nanometric scale from a layer to be structured. The layer to be structured is arranged between a substrate and a mask structure that is formed on the layer to be structured. The mask structure, on the edges thereof, produces an elastic stress field in the layer to be structured and in the substrate. The method is characterized by the following steps: masked areas of the layer to be structured are separated from one another by non-masked areas in order to form a first structure; the elastic stress is laterally shifted in relation to the surface of the layer to be structured, and; areas of the layer to be structured are separated from one another by a stress-dependent diffusion in order to form a second structure. By using additional locally applied protective layers, this enables the production of structures and, in particular, wires having a width of 10-500 nm. These structures can be used for electrical components, e.g. in the field of semiconductor technology.

    Abstract: A method for making frontside contact to a substrate through an SOI (20) structure thereon is provided. An etching step is undertaken to form a trench (32) in the SOI structure so as to expose and define a rough surface (34) of the substrate. Then, a thin insulating layer (40), for example SiO2, is formed over the exposed surface of the substrate, this insulating layer being irregular because of its formation over the relatively rough etched surface. Contact material (42) is provided in the trench, and electrical potential is applied across the contact and substrate sufficient to increase the conductivity of the insulating layer (40), i.e., to break down the insulating layer. Nitrogen may be implanted into the exposed surface of the substrate to slow subsequent growth of the insulating layer, resulting in an even thinner insulating layer, i.e., one even less resistant to breakdown upon application of electrical potential thereacross. If the insulating layer thereon is sufficiently thin or irregular, ohmic contact may be achieved between the contact and substrate without the application of such electrical potential. In yet another embodiment, prior to formation of the insulating layer, the exposed surface of the substrate and wall of the trench are fabricated such that meet at an abrupt angle. Insulating material formed in this area is of poor quality, readily lending itself to breakdown upon application of electrical potential across the contact material and substrate.

    Abstract: A semiconductor component comprising a highly doped layer on a substrate layer and delimited by at least one trench extending from the surface of the component through the highly doped layer, also comprises a sub-layer between the substrate layer and the highly doped layer, said sub-layer being doped with the same type of dopant as the buried collector, but to a lower concentration. A method for manufacturing such a component is also disclosed. The sub-layer causes a more even distribution of the potential lines in the substrate and in the subcollector layer, thereby avoiding areas of particularly dense potential lines. Since the breakdown voltage is lower in areas with dense potential lines, avoiding too dense potential lines means increasing the breakdown voltage of the component.
