  • Publication number: 20110140279
    Abstract: Disclosed are embodiments of a semiconductor structure that incorporates multiple nitride layers stacked between the center region of a device and a blanket oxide layer. These nitride layers are more thermally conductive than the blanket oxide layer and, thus provide improved heat dissipation away from the device. Also disclosed are embodiments of a method of forming such a semiconductor structure in conjunction with the formation of any of the following nitride layers during standard processing of other devices: a nitride hardmask layer (OP layer), a “sacrificial” nitride layer (SMT layer), a tensile nitride layer (WN layer) and/or a compressive nitride layer (WP layer).

  • Publication number: 20110134504
    Abstract: A tiltable micro-electro-mechanical (MEMS) system lens comprises a microscopic lens located on a front surface of a semiconductor-on-insulator (SOI) substrate and a semiconductor rim surrounding the periphery of the microscopic lens. Two horizontal semiconductor beams located at different heights are provided within a top semiconductor layer. The microscopic lens may be tilted by applying an electrical bias between the lens rim and one of the two semiconductor beams, thereby altering the path of an optical beam through the microscopic lens. An array of tiltable microscopic lenses may be employed to form a composite lens having a variable focal length may be formed. A design structure for such a tiltable MEMS lens is also provided.

  • Patent number: 7935638
    Abstract: Methods and structures for enhancing the homogeneity in a ratio of perimeter to surface area among heterogeneous features in different substrate regions. At least one shape on the substrate includes an added edge effective to reduce a difference in the perimeter-to-surface area ratio between the features in a first substrate region and features in a second substrate region. The improved homogeneity in the perimeter-to-surface area ratio reduces variations in a thickness of a conformal layer deposited across the features in the first and second substrate regions.

  • Publication number: 20110098838
    Abstract: Disclosed are a system and a method of correcting systematic, design-based, parametric variations on integrated circuit chips to minimize circuit limited yield loss. Processing information and a map of a chip are stored. The processing information can indicate an impact, on a given device parameter, of changes in a value for a specification associated with a given process step. The map can indicate regional variations in the device parameter (e.g., threshold voltage). Based on the processing information and using the map as a guide, different values for the specification are determined, each to be applied in a different region of the integrated circuit chip during the process step in order to offset the mapped regional parametric variations. A process tool can then be selectively controlled to ensure that during chip manufacturing the process step is performed accordingly and, thereby to ensure that the regional parametric variations are minimized.

  • Publication number: 20110073985
    Abstract: A solution for alleviating variable parasitic bipolar leakages in scaled semiconductor technologies is described herein. Placement variation is eliminated for edges of implants under shallow trench isolation (STI) areas by creating a barrier to shield areas from implantation more precisely than with only a standard photolithographic mask. An annealing process expands the implanted regions such their boundaries align within a predetermined distance from the edge of a trench. The distances are proportionate for each trench and each adjacent isolation region.

  • Patent number: 7914949
    Abstract: A method, a recording medium and an apparatus for testing a photomask are provided. In the disclosed method, a particular region of a photomask is selected, either from a physical instance of the photomask, or from the photomask as represented by a digital representation thereof. The particular region is then characterized by identifying a pattern type present in the particular region. A lithographic process stress condition is determined for the particular region, considering the pattern type, and thereafter, a result of lithographically patterning a feature is determined by simulating a photolithographic exposure, using the particular region of the photomask under the lithographic process stress condition. Then, it is decided whether the particular region of the photomask is acceptable based on the result of the simulated exposure only under the lithographic process stress condition.

  • Publication number: 20110049724
    Abstract: Methods for forming voids in BEOL interconnect structures and BEOL interconnect structures. The methods include forming a temporary feature on a top surface of a first dielectric layer and depositing a second dielectric layer on the top surface of the first dielectric layer. The temporary feature is removed from the second dielectric layer to define a void in the second dielectric layer that is laterally adjacent to a conductive feature in the second dielectric layer. The void operates to reduce the effective dielectric constant of the second dielectric layer, which reduces parasitic capacitance between the conductive feature and other conductors in the BEOL interconnect structure.
