  • Patent number: 8802561
    Abstract: Techniques disclosed herein prevent wire flaking (collapse). One aspect is an improved way of forming wires over trenches, which may be located in a hookup region of a 3D memory array, and may be used to form electrical connections between conductive lines in the memory array and drivers. The trenches are formed between CMP dummy structures. The trenches are partially filled with a flowable oxide film, which leaves a gap in the trench that is at least as wide as the total pitch of the wires to be formed. A capping layer is formed over the flowable film. After forming a conductive layer over the dielectric layer, the conductive layer is etched to form conductive wires. Some of the capping layer, as well as the CMP dummy structures may be removed. Thus, the conductive wires may be at least temporarily supported by lines of material formed from the capping layer.

  • Patent number: 8580697
    Abstract: The present invention meets these needs by providing improved methods of filling gaps. In certain embodiments, the methods involve placing a substrate into a reaction chamber and introducing a vapor phase silicon-containing compound and oxidant into the chamber. Reactor conditions are controlled so that the silicon-containing compound and the oxidant are made to react and condense onto the substrate. The chemical reaction causes the formation of a flowable film, in some instances containing Si—OH, Si—H and Si—O bonds. The flowable film fills gaps on the substrates. The flowable film is then converted into a silicon oxide film, for example by plasma or thermal annealing. The methods of this invention may be used to fill high aspect ratio gaps, including gaps having aspect ratios ranging from 3:1 to 10:1.

  • Patent number: 8450854
    Abstract: The present invention provides an interconnect structure in which a patternable low-k material is employed as an interconnect dielectric material. Specifically, this invention relates to single-damascene and dual-damascene low-k interconnect structures with at least one patternable low-k dielectric. In general terms, the interconnect structure includes at least one patterned and cured low-k dielectric material located on a surface of a substrate. The at least one cured and patterned low-k material has conductively filled regions embedded therein and typically, but not always, includes Si atoms bonded to cyclic rings via oxygen atoms. The present invention also provides a method of forming such interconnect structures in which no separate photoresist is employed in patterning the patterned low-k material.

    Abstract: A mechanically robust semiconductor structure with improved adhesion strength between a low-k dielectric layer and a dielectric-containing substrate is provided. In particular, the present invention provides a structure that includes a dielectric-containing substrate having an upper region including a treated surface layer which is chemically and physically different from the substrate; and a low-k dielectric material located on a the treated surface layer of the substrate. The treated surface layer and the low-k dielectric material form an interface that has an adhesion strength that is greater than 60% of the cohesive strength of the weaker material on either side of the interface. The treated surface is formed by treating the surface of the substrate with at least one of actinic radiation, a plasma and e-beam radiation prior to forming of the substrate the low-k dielectric material.

  • Patent number: 8440579
    Abstract: Patterning-induced damage of sensitive low-k dielectric materials in semiconductors devices may be restored to a certain degree on the basis of a surface treatment that is performed prior to exposing the device to ambient atmosphere. To this end, the dangling silicon bonds of the silicon oxide-based low-k dielectric material may be saturated in a confined process environment, thereby providing superior surface conditions for the subsequent application of an appropriate repair chemistry.
