  • Patent number: 7957437
    Abstract: Disclosed is a semiconductor laser in which the substrate comprises at least three independent functional sections in the direction of light wave propagation, said functional sections serving different functions and being individually triggered by means of electrodes via electrode leads. An intensification zone, a grid zone, and a phase adjustment zone are provided as functional sections. The light wave is optically intensified in the intensification zone while the phase of the advancing and returning wave is adjusted in the phase adjustment zone. The grid zone is used for selecting the wavelength and adjusting the intensity of coupling between the intensification zone and the phase adjustment zone.

  • Patent number: 7772126
    Abstract: An interlayer is disposed on a pattern surface of a substrate. A buried hard mask may be provided on the interlayer. The buried hard mask includes a template opening having a template length along a line axis and a template width perpendicular thereto. The buried hard mask is filled with a fill material. A top mask is provided above the filled buried hard mask. The top mask includes a trim opening crossing the template opening and having a trim width along the line axis that is smaller than the template length. By etching the fill material and the interlayer using the top and buried hard mask a process section of the pattern surface may be exposed such that a target length and width of the process section result from the template and the trim widths. The planar dimensions of the process section may be decoupled from each other.

  • Publication number: 20090323411
    Abstract: Method including selective treatment of storage layer. One embodiment includes the formation of a material layer on a topology with protruding portions, which may be assigned to active areas, and with recessed portions, which may be assigned to isolation structures. A mask material is deposited that grows selectively above the protruding portions and that forms a mask which covers first portions of the material layer wrapping around at least portions of the protruding portions. Openings in the mask are formed above second portions of the material layer above the recessed portions. Then the material layer is treated in the second portions in a self-aligned manner.

  • Patent number: 7521351
    Abstract: A semiconductor product includes, a substrate with a first dielectric layer having contact hole fillings for contacting active areas in the substrate. A second dielectric layer with contact holes is provided therein. The contact holes have a width in a first lateral direction. The product further includes conductive lines, each conductive line passing over contact holes in the second dielectric layer and contacting a plurality of contact hole fillings in the first dielectric layer. The conductive lines have a width, in the first lateral direction, that is smaller than the width of the contact holes of the second dielectric layer. The conductive lines are in direct mechanical contact with the contact hole fillings and thereby remove the need to provide any conventional “contact to interconnect” structures.
