The invention provides a method of fracturing, including the provision and use of a fracturing fluid suspension containing an effective amount of a solid particulate breaker material having delayed breaking or degradation characteristics, additionally including an amount of durable fibers and/or platelets sufficient to enhance wellbore solids, such as proppant, transport. In a preferred aspect, solid particulate matter, which comprises or is composed of a specified organic polymeric compound or composition having an average molecular weight of at least 10,000, or a mixture of such compounds or compositions, and which solid organic polymeric matter reacts or decomposes, as described, is combined in a fracturing fluid with or containing a specified gellant and proppant, to form a fracturing fluid suspension, and the suspension formed is pumped downwell and deposited as a gelled suspension in the subterranean formation, generally under fracturing conditions.

A photoresist-free method for making patterned films of metal oxides, metals, or other metal containing compounds is described. The method involves applying an amorphous film of a metal complex to a substrate. The film may be conveniently applied by spin coating using standard industry techniques. The metal complex used is photoreactive and undergoes a low temperature chemical reaction in the presence of light of a suitable wavelength. The end product of the reactions depends upon the atmosphere in which the reactions take place. Metal oxide films may be made in air. Patterned films may be made by exposing only selected portions of the film to light. Patterns of two or more materials may be laid down from the same film by exposing different parts of the film to light in different atmospheres. The resulting patterned film is generally planar. Separate planarization steps are not generally required.

A slurry for use in a chemical mechanical planarization process for a wafer comprises a chemical portion and a mechanical portion. The chemical portion comprises a surfactant that forms a layer over a metallic layer of the wafer to decreasing dishing to less than an average of 843 Å reduce the static etch rate of the metallic layer. The mechanical portion comprises an abrasive agent to assist in the planarization of the metallic layer of the wafer. In another embodiment, a slurry for polishing a copper layer formed over a first layer is disclosed. The slurry comprises an abrasive agent; and a surfactant comprising at least one non-ionic surfactant to reduce the static etch rate of the copper layer. The shelf life of the slurry exceeds 90 days.

An effective method for forming through-base wafer vias in the fabrication of stacked devices is described. The base wafer can be a silicon wafer in which case the method relates to TSV (through-silicon via) technology. The method affords high removal rates of both silicon and metal (e.g., copper) under appropriate conditions and is tuneable with respect to base wafer material to metal selectivity.
摘要:
A method and associated composition for chemical mechanical planarization of a chalcogenide-containing substrate (e.g., germanium/antimony/tellurium (GST)-containing substrate) are described. The composition and method afford low defect levels as well as low dishing and local erosion levels on the chalcogenide-containing substrate during CMP processing.
