A method of making a combustion turbine component includes assembling a plurality of metallic combustion turbine subcomponent greenbodies together to form a metallic greenbody assembly and sintering the metallic greenbody assembly to thereby form the combustion turbine component. Each of the plurality of metallic combustion turbine subcomponent greenbodies may be formed by direct metal fabrication (DMF). In addition, each of plurality of metallic combustion turbine subcomponent greenbodies may include an activatable binder and the activatable binder may be activated prior to sintering.

A typical integrated-circuit fabrication requires interconnecting millions of microscopic transistors and resistors with aluminum wires. Yet, aluminum wires have greater electrical resistance and are less reliable than copper wires. Unfortunately, current techniques for making copper wires are time-consuming and inefficient. Accordingly, the invention provides a method of making wires or interconnects from copper or other metals. One embodiment entails forming a first diffusion barrier inside a trench using ionized-magnetron sputtering for better conformal coating of the trench, and a second diffusion barrier outside the trench using jet-vapor deposition. The jet-vapor deposition has an acute angle of incidence which prevents deposition within the trench and thus eliminates conventional etching steps that would otherwise be required to leave the trench free of this material. After formation of the two diffusion barriers, the trench is filled with metal and annealed.

The present invention relates to a float collar apparatus for regulating the passage of fluid through a drilling/production liner or sub-sea casing. Apparatus of the present invention is fabricated using plastic flapper valves and valve-actuating sleeve components in contrast to prior art float collar components which are fabricated almost entirely of hard metals. Particularly, the plastic may be nylon, phenolic, or a phenolic-nylon laminate. The use of plastic components in the float collar apparatus of the present invention provides a substantial reduction in time and resources expended during drilling out of the float collar once cementing operations are completed. Additionally, the float collar apparatus of the present invention is fabricated from a pre-determined combination of plastic components and metal components thereby ensuring that the improved float collar can still endure substantial hydrostatic stresses encountered during casing liner running in and cementing operations.

The pages may be configured by users, and systems and parameters of interest selected.

In recent years, copper wiring has emerged as a promising substitute for the aluminum wiring in integrated circuits, because copper offers lower electrical resistance and better reliability at smaller dimensions than aluminum. However, use of copper typically requires forming a diffusion barrier to prevent contamination of other parts of an integrated circuit and forming a seed layer to facilitate copper plating steps. Unfortunately, conventional methods of forming the diffusion barriers and seed layers require use of separate wafer-processing chambers, giving rise to transport delays and the introduction of defect-causing particles. Accordingly, the inventors devised unique wafer-processing chambers and methods of forming barrier and seed layers. One embodiment of the wafer-processing chamber includes equipment for physical vapor deposition and equipment for chemical vapor deposition to facilitate formation of diffusion barriers and seed layers within one chamber, thereby promoting fabrication efficiency and reducing defects.

A method for processing IC designs for different metal BEOL processes is provided for enabling fabricating using a metal fabrication process an IC originally having a backend design for a different metal fabrication process. The method first determines layer constructions of an original design of an IC for a first metal backend process, and, based on the layer constructions of the original design of the IC, constructs primitive layer constructions of a target design of the IC for a second metal backend process. The method then tunes an effective dielectric constant of a dielectric layer of the target design to match an associated capacitance of the target backend design with a corresponding capacitance of the original backend design. The method can be used to convert a backend design of an IC from an old metal process (such as Al process) to a new metal process (such as Cu process), without redesigning the IC for the new metal BEOL fabrication process.

A gutter cover is formed through expanded metal manufacturing techniques to create alternating areas of solid metal and diamond-shaped openings to facilitate the shedding of leaves while passing water into the gutter. The gutter cover is mounted without fasteners by securing a hook portion underneath the front lip of the gutter and arcing the body portion of the gutter cover to press the rearward drip foot against the gutter and the drip hip adjacent to the fascia board into a pressure fit. The length of the gutter cover from the rearward edge to the front end being slightly longer than the corresponding length of the gutter structure. The gutter cover includes an integral drip leg projecting downwardly from the drip hip and being formed with an area of expanded metal diamond-shaped apertures to direct water into the gutter trough. A front drip lip directs water away from the gutter face.

Parameters to be used as the basis for comparison may also be selected. Pages illustrating the comparisons may be generated and transmitted to the user based upon the selections.

A capacitor structure is fabricated with only slight modifications to a conventional single-poly CMOS process. After front-end processing is completed, grooves are etched through the pre-metal dielectric layer to expose polysilicon structures, which may be salicided or non-salicided. A dielectric layer is formed over the exposed polysilicon structures. A conventional contact process module is then used to form contact openings through the pre-metal dielectric layer. The mask used to form the contact openings is then removed, and conventional contact metal deposition steps are performed, thereby simultaneously filling the contact openings and the grooves with the contact (electrode) metal stack. A planarization step removes the upper portion of the metal stack, thereby leaving metal contacts in the contact openings, and metal electrodes in the grooves. The metal electrodes may form, for example, transistor gates, EEPROM control gates or capacitor plates.

Disclosed is a metal casting system, an engineered mold for use therewith, a process for utilizing the system and mold, and articles having a clean, oxide-free sand casting of molten metals that have been produced under an inert environment.
