  • Patent number: 8476160
    Abstract: A first low dielectric constant (low-k) dielectric material layer is lithographically patterned to form a recessed region having expose substantially vertical sidewalls, which are subsequently damaged to de-carbonize a surface portion at the sidewalls having a sublithographic width. A second low-k dielectric material layer is deposited to fill the recessed region and planarized to exposed top surfaces of the damaged low-k dielectric material portion. The damaged low-k dielectric material portion is removed selective to the first and second low-k dielectric material layers to form a trench with a sublithographic width. A portion of the pattern of the sublithographic-width trench is transferred into a metallic layer and optionally to an underlying dielectric masking material layer to define a trench with a sublithographic width, which can be employed as a template to confine the widths of via holes and line trenches to be subsequently formed in an interconnect-level dielectric material layer.

  • Patent number: 8461642
    Abstract: The present invention can realize a highly-integrated semiconductor device having a MONOS type nonvolatile memory cell equipped with a split gate structure without deteriorating the reliability of the device. A memory gate electrode of a memory nMIS has a height greater by from 20 to 100 nm than that of a select gate electrode of a select nMIS so that the width of a sidewall formed over one (side surface on the side of a source region) of the side surfaces of the memory gate electrode is adjusted to a width necessary for achieving desired disturb characteristics. In addition, a gate electrode of a peripheral second nMIS has a height not greater than the height of a select gate electrode of a select nMIS to reduce the width of a sidewall formed over the side surface of the gate electrode of the peripheral second nMIS so that a shared contact hole is prevented from being filled with the sidewall.

  • Patent number: 8461655
    Abstract: A method for manufacturing a micromechanical sound transducer includes depositing successive layers of first and second membrane support material on a first main surface of a substrate arrangement with a first etching rate and a lower second etching rate, respectively. A layer of membrane material is then deposited. A cavity is created in the substrate arrangement from a side of the substrate arrangement opposite to the membrane support materials and the membrane material at least until the cavity extends to the layer of first membrane support material. The layers of first and second membrane support material are etched by applying an etching agent through the cavity in at least one first region located in an extension of the cavity also in a second region surrounding the first region. The etching creates a tapered surface on the layer of second membrane support material in the second region.
