  • Patent number: 10546850
    Abstract: A semiconductor device includes semiconductor fins on semiconductor strips on a substrate. The semiconductor fins are parallel to each other. A gate stack is over the semiconductor fins, and a drain epitaxy semiconductor region is disposed laterally from a side of the gate stack and on the semiconductor strips. A first dielectric layer is over the substrate, and the first dielectric layer has a first metal layer. A second dielectric layer is over the first dielectric layer, and the second dielectric layer has a second metal layer. Vias extend from the second metal layer and through the first dielectric layer, and the vias are electrically coupled to the drain epitaxy semiconductor region.

  • Publication number: 20070212849
    Abstract: The present invention relates to a method of fabricating a groove-like structure in a semiconductor device including etching a trench in a substrate, filling the trench with a spin-on-glass liquid forming a spin-on-glass liquid layer containing a solvent, baking the spin-on-glass liquid layer in order to remove the solvent and forming a baked layer, etching the baked layer to a predetermined depth using an etchant that provides a larger etch rate with regard to silicon than with regard to silicon nitride or silicon oxide, and, after etching the baked layer, annealing the remaining baked layer and forming a spin-on-glass oxide layer inside the trench.

  • Publication number: 20070082504
    Abstract: The invention refers to a pre-metal dielectric semiconductor structure comprising a substrate, having features on a surface of the substrate, wherein the features are spaced from at least one gap between the features. The gap is filled with an advantageous layer combination. The layer combination comprises at least one spin-on dielectric layer. Additionally a further insulating layer is disposed or a further silicate glass layer doped with phosphorus is arranged. Using this layer combination, the filling of the gap with less or no voids and advantageous chemical and/or mechanical and/or electrical features is attained.
