  • Publication number: 20120025166
    Abstract: Nanosized filamentary carbon structures (CNTs) nucleating over a catalyzed surface may be grown in an up-right direction reaching a second surface, spaced from the first surface, without the need of applying any external voltage source bias. The growth process may be inherently self-stopping, upon reaching a significant population of grown CNTs on the second surface. A gap between the two surfaces may be defined for CNT devices being simultaneously fabricated by common integrated circuit integration techniques. The process includes finding that for separation gaps of up to a hundred or more nanometers, a difference between the respective work functions of the materials delimiting the gap space, for example, different metallic materials or a doped semiconductor of different dopant concentration or type, may produce an electric field intensity orienting the growth of nucleated CNTs from the surface of one of the materials toward the surface of the other material.

  • Publication number: 20120020400
    Abstract: A method for identifying a corrupted received signal at a receiver is described. A received signal may include symbols. Each symbol may have a value of a Galois field associated therewith. The receiver may be configured to store a logarithm of normalized probability mass functions and corresponding Galois field values for each of the plurality of symbols. The normalized probability mass functions may be normalized with respect to a greatest probability mass function of a given symbol of the plurality of symbols. The method may include comparing, for each of the plurality of symbols, a logarithm of normalized probability of an n-th best probability value with a respective threshold, counting a number of the logarithms that exceed the respective threshold and generating, for each of the plurality of symbols, a score corresponding to the number.

  • Publication number: 20120023580
    Abstract: The method for detecting an attack by fault injection into memory positions includes a generation of an initial value of a reference indication including an application of a reversible mathematical operator to the values of the information stored in the memory positions. An updating of the value of this reference indication is performed on each write in at least one memory position by using the operator, the reverse operator and the values of the stored information before and after each write in the at least one memory position. And, in the presence of a request, a check is performed as to whether a criterion involving the values of the information stored in the memory positions at the time of the request and the operator or its reverse is or is not satisfied by the value of the reference indication at the time of the request.

  • Publication number: 20120018819
    Abstract: A process for manufacturing a micromechanical structure envisages: forming a buried cavity within a body of semiconductor material, separated from a top surface of the body by a first surface layer; and forming an access duct for fluid communication between the buried cavity and an external environment. The method envisages: forming an etching mask on the top surface at a first access area; forming a second surface layer on the top surface and on the etching mask; carrying out an etch such as to remove, in a position corresponding to the first access area, a portion of the second surface layer, and an underlying portion of the first surface layer not covered by the etching mask until the buried cavity is reached, thus forming both the first access duct and a filter element, set between the first access duct and the same buried cavity.

  • Publication number: 20120019676
    Abstract: In automatically focusing on a subject in the field of view of a camera device, the camera device sets a focal length successively at one or more focal positions with an angle of the focus plane tilted so as not to be orthogonal to a normal optical path through the camera device. An image is taken at each of the focal positions. A comparison of data from each image is made so as to determine best focus. This comparison includes comparing data from at least two different locations along the tilted focus plane of at least one of the images.

  • Publication number: 20120021606
    Abstract: A process for producing two interleaved patterns on a substrate uses photolithography and etching to produce, on the substrate, a first pattern of first material protruding regions separated by recessed regions. A non-conformal deposition of a second material on the first pattern forms cavities in the recessed regions of the first pattern. These cavities are opened and filled with a third material. The second material is then removed, and the remaining third material forms a second pattern of third material protruding regions, wherein the second pattern is interleaved with the first pattern.

  • Publication number: 20120018889
    Abstract: A process for producing an upper metallization level and a via level connecting this upper metallization level to a lower metallization level includes: producing an insulating region on the lower metallization level; producing a hard mask on the insulating region (4, 5) defining the position of the via and metallic line of the upper metallization level; etching the insulating region through the hard mask so as to form a cavity; cleaning the cavity (which forms an undercut at the interface between the hard mask and the insulating region); and completely filling the cavity. The step of completely filling includes at least partially filling the cavity with copper and plugging the undercut. The undercut is plugged by sputtering a plugging material and forming an overlying doped copper layer.
