  • Patent number: 7973417
    Abstract: An article including a substrate having a blind hole formed therein, wherein the blind hole is defined by a floor and a sidewall and a solder connection is provided. The solder connection may couple a first contact pad to a second contact pad. The first contact pad may cover a first field of the floor of the blind hole, and may also promote wetting of a solder material of the solder connection. Wetting may be impeded on a second field of the floor of the blind hole. The second contact pad may be arranged above a surface of a further substrate, wherein the surface of the further substrate may be oriented perpendicularly to the floor of the blind hole in the substrate.

  • Patent number: 6708405
    Abstract: A method is described for producing a conducting connection through insulating layers by way of a contact hole and conducting materials with which the contact hole is filled. The method permits the production of a contact hole resembling the shape of a wineglass, into which conducting filling material and barrier layers can be inserted without the known problems such as void formation, overetching trenches, and dielectric close-off. It is possible in this way, for example, to produce an electric connection between the diffusion zone of a selection transistor and the lower electrode of a storage capacitor of large-scale integrated DRAM and FeRAM components with the aid of only a few mask steps.

  • Patent number: 6309930
    Abstract: The SRAM cell arrangement comprises six MOS transistors per memory cell that are fashioned as vertical transistors. The MOS transistors are arranged at sidewalls of trenches (G1, G2, G4). Parts of the memory cell such as, for example, gate electrodes (Ga2, Ga4) or conductive structures (L3) fashioned as spacer are contacted via adjacent, horizontal, conductive structures (H5) arranged above a surface (O) of a substrate (S). Connections between parts of memory cells ensue via third conductive structures (L3) arranged at the sidewalls of the depressions and word lines (W) via diffusion regions (D2) that are adjacent to the sidewalls of the depressions within the substrate (S), via first bit lines, via second bit lines (B2) or/and via conductive structures (L1, L2, L6) that are partially arranged at different height with respect to an axis perpendicular to the surface (O). Contacts (K5) contact a plurality of parts of the MOS transistors simultaneously.

  • Patent number: 6118159
    Abstract: The memory cell configuration comprises vertical transistors which are connected in a NOR architecture. The vertical transistors are disposed on flanks of trenches. Each vertical transistor includes an electrically insulated floating gate electrode, whose charge can be varied by Fowler-Nordheim tunneling due to a voltage drop between a control gate electrode and a source/drain region. The length of a coupling area in a direction parallel to a channel width, between the control gate electrode and the floating gate electrode is less than the channel width, in order to reduce the operating voltage. This is achieved by thermal oxidation of parts of the flanks of the trenches. Transistors which are adjacent in a direction transverse to the trenches share bit lines. Each bit line has a lightly doped first part and a highly doped second part. The coupling area can be enlarged even further by using a strip-shaped mask, which is extended by spacers.

  • Patent number: 4380489
    Abstract: Polysilicon structures down to a 1 .mu.m range on substrates containing integrated semiconductor circuits are produced by plasma etching in a plate reactor with the use of SF.sub.6 and an inert gas as the reactive gas. During this process, a semiconductor crystal wafers (4, 17) covered with a SiO.sub.2 layer (16) and a polysilicon layer (15) is provided with an etch mask (14) and positioned on a grounded electrode of the plate reactor and an etching process, which achieves a high selectivity of polysilicon (15) to SiO.sub.2 (16) and to the etch mask (14), is carried out with a HF power, P, of <0.1 watt/cm.sup.2, a gas pressure, p, ranging from 60 to 120 Pa, and an electrode temperature ranging from 20.degree. to 60.degree. C. With the inventive process, large scale integrated semiconductor circuits are produced in a single stage sequence with high etching selectivity, uniform etching and a high throughput of silicon wafers.
