The inter-level dielectric layer in such a structure has a much lower dielectric constant, reduces RC delay between devices of integrated circuits and also is easy to integrate; besides, since the holes within the dielectric layer are non-interconnected, they shall not cause change to the dielectric constant of the dielectric material or a short circuit between wires, thus the device shall have better stability and reliability which thence improve performance of the circuit.

  • Publication number: 20120187522
    Abstract: A substrate is provided. An STI trench is formed in the substrate. A fill material is formed in the STI trench and then planarized. The substrate is exposed to an oxidizing ambient, growing a liner at a bottom and sidewalls of the STI trench. The liner reduces the Vt-W effect in high-k metal gate devices.

  • Publication number: 20120168898
    Abstract: A single crystal silicon etching method includes providing a single crystal silicon substrate having at least one trench therein. The single crystal silicon substrate is exposed to an anisotropic etchant that undercuts the single crystal silicon. By controlling the length of the etch, single crystal silicon islands or smooth vertical walls in the single crystal silicon may be created.

  • Publication number: 20120162622
    Abstract: Techniques are provided for efficient lithography processing and wafer layout. In particular, the techniques can be used to reduce the number of sacrificial exposures along the wafer perimeter region. In one example embodiment, an exposure system reticle is configured with both a normal area (die yielding area) and a dumification area (non-yielding area at wafer perimeter), thereby allowing for lithographic processing in the non-yielding areas sufficient to facilitate successful processing in the adjacent die yielding areas, but without requiring additional sacrificial exposures. This reduction in sacrificial exposures translates to a significant improvement in fab capacity. The techniques can be implemented, for example, on any number of lithography tools having an adjustable reticle or reticle blind capability and in the context of any technology nodes, such as 95 nm and smaller. The lithography tool may produce wafers at a faster rate.

  • Publication number: 20120126359
    Abstract: A structure for reducing partially etched materials is described. The structure includes a layout of an intersection area between two trenches. First, a large intersection area having a trapezoidal corner may be replaced with an orthogonal intersection between two trenches. The layout reduces the intersection area as well as the possibility of having partially etched materials left at the intersection area. The structure also includes an alternative way to fill the intersection area with either an un-etched small trapezoidal area or multiple un-etched square areas, so that the opening area at the intersection point is reduced and the possibility of having partially etched materials is reduced too.

    Abstract: A semiconductor power device includes an active region configured to conduct current when the semiconductor device is biased in a conducting state, and a termination region along a periphery of the active region. The termination region includes a first silicon region of a first conductivity type extending to a first depth within a second silicon region of a second conductivity type, the first and second silicon regions forming a PN junction therebetween. The second silicon region has a recessed portion extending below the first depth and out to an edge of a die housing the semiconductor power device. The recessed portion forms a vertical wall at which the first silicon region terminates. A first conductive electrode extends into the recessed portion and is insulated from the second silicon region.
