A pneumatic turbine motor air chamber drives a pneumatic turbine to rotate through compressed air. The pneumatic turbine has a ring extended from inside thereof that has a plurality of barriers and forms a housing space to hold a speed regulator. The pneumatic turbine also has an air intake coupling hole leading to the housing space and at least one air discharge vent communicating with an air passage to discharge the compressed air. The ring is integrally formed with the pneumatic turbine to enhance operation steadiness of the pneumatic turbine.

A method for forming a via in a damascene process. In one embodiment, the present method comprises depositing a material into a via formed using a damascene process. More particularly, in one embodiment, the material which is comprised of a substantially conformal material which has an etch selectivity with respect to the substrate into which the via is formed. Furthermore, in this embodiment, the material is deposited along the sidewalls and the base of the via. Next, the present embodiment etches material such that the via is formed having a profile conducive to the adherence of overlying material thereto. In this embodiment, the etching of the material is performed without substantially etching the substrate into which the via is formed. In so doing, the present embodiment creates a via in a damascene process which allows for the formation of a metallized interconnect which is substantially free of voids.

A process for fabricating a CMOS device in which conductive gate structures are defined self-aligned to shallow trench isolation (STI), regions, without using a photolithographic procedure, has been developed. The process features definition of shallow trench openings in regions of a semiconductor substrate not covered by dummy gate structures, or by silicon oxide spacers located on sides of the dummy gate structures. Filling of the shallow trench openings with silicon oxide, and removal of the dummy gate structures, result in STI regions comprised of filled shallow trench openings, overlying silicon oxide shapes, and silicon oxide sidewall spacers on the sides of the overlying silicon oxide shapes. Formation of silicon nitride spacers on the sides of the STI regions, is followed by deposition of a high k gate insulator layer and of a conductive gate structure, with the conductive gate structure formed self-aligned to the STI regions.

A float device is disclosed with an improved external surface having an outwardly concave curvature and a plurality of elongated grooves spirally formed on the concave surface. The concave surface provides improved clearance between the float device and the walls of the pipe that it is disposed in. Therefore, the float device is less subject to being lodged or stuck especially in highly viscous liquids. The spiral grooves provide additional passageway and stability by imparting rotational torque to the floating device when measuring flow rates in moving fluids in pipes. In another embodiment, the float device is annular in shape having an inner surface with a curvature and spiral grooves. Same improved effects are obtained as the float device rides up and down a column like a collar in measuring the fluid level or fluid flow rates.

There is a need for adjustable capacitors for use in LC or RC matching networks in micro-circuits. This has been achieved by forming a set of individual capacitors that share a common bottom electrode. The areas of the top electrodes of these individual capacitors are chosen to be in an integral ratio to one another so that they can be combined to produce any capacitance within a range of unit values. For example, if four capacitors whose areas are in the ratio of 5:2:1:1, are provided, then any capacitance in a range of from 1 to 9 can be generated, depending on how the top electrodes are connected. Such connections can be hard-wired within the final wiring level to provide a factory adjustable capacitor or they can be connected through field programmable devices to produce a field programmable capacitor. A process for manufacturing the device is also described.

A semiconductor wafer carrier fork cover to prevent damage to prevent breakage of the semiconductor wafer carrier forks mounted on a robotic semiconductor wafer transfer system during preventative maintenance procedures is described. A semiconductor wafer carrier fork cover has a lower support unit. The lower support unit will fit onto the base of a robotic semiconductor wafer transfer system. An upper covering unit is integrally attached to the lower support unit and will shield the semiconductor wafer carrier forks during preventive maintenance procedures.

A method and apparatus for reducing gouging during via formation. In one embodiment, the present invention is comprised of a method which includes forming an opening into a substrate. The opening is formed extending into the substrate and terminating on at least a portion of a target to which it is desired to form an electrical connection. After the formation of the opening, the present embodiment lines the opening with a liner material. In this embodiment, the liner material is adapted to at least partially fill a portion of the opening which is not landed on the target. The liner material of the present embodiment prevents substantial further etching of the substrate conventionally caused by the opening being at least partially unlanded on the target. Next, the present embodiment subjects the liner material to an etching process such that the liner material is substantially removed from that region of the target where the opening was landed on the target. In this embodiment, liner material residing in the region where the opening is unlanded prevents further gouging of the substrate proximate to the target.
摘要:
A method for making metal-insulator-metal (MIM) capacitors having insulators with high-dielectric-constant or ferroelectric interelectrode films compatible with the dual-damascene process is achieved. The method of integrating the MIM with a dual-damascene process is to form a planar a first insulating layer and to deposit an etch-stop layer and a second insulating layer. Capacitor node contact openings are etched to the substrate and first recesses are etched to the etch-stop layer. The contact openings and first recesses are filled with a conducting layer using a dual-damascene process. Second recesses are formed in the second insulating layer around the capacitor node contacts. A conformal first metal layer, an interelectrode dielectric layer, and a second metal layer are deposited, and are patterned at the same time to form the capacitors over the node contacts. The second recesses increase the capacitor area while the simultaneous patterning of the metal layers results in fewer processing steps.
