摘要:
An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved protection for the bottom portion of the gate structure. In some embodiments, the method achieves improved protection for gate structure bottom by forming a recess on either side of the gate structure and placing spacers on the side walls of the gate structure, so that the spacers protect the portion of the gate structure below the gate dielectric layer.

Methods and apparatus for hybrid MOS capacitors in replacement gate process. A method is disclosed including patterning a gate dielectric layer and a polysilicon gate layer to form a polysilicon gate region over a substrate; forming an inter-level dielectric layer over the substrate and surrounding the polysilicon gate region; defining polysilicon resistor regions each containing at least one portion of the polysilicon gate region and not containing at least one other portion of the polysilicon gate region, forming dummy gate regions removing the dummy gate regions and the gate dielectric layer underneath the dummy gate regions to leave trenches; and forming high-k metal gate devices in the trenches. A capacitor region including a high-k metal gate and a polysilicon gate next to the high-k metal gate is disclosed. Additional hybrid capacitor apparatuses are disclosed.

A combustor for a gas turbine engine is disclosed which is able to operate with high combustion efficiency, and low nitrous oxide emissions during gas turbine operations. The combustor consists of a can-type configuration which combusts fuel premixed with air and delivers the hot gases to a turbine. Fuel is premixed with air through a swirler and is delivered to the combustor with a high degree of swirl motion about a central axis. This swirling mixture of reactants is conveyed downstream through a flow path that expands; the mixture reacts, and establishes an upstream central recirculation flow along the central axis. A cooling assembly is located on the swirler co-linear with the central axis in which cooler air is conveyed into the prechamber between the recirculation flow and the swirler surface.

An improved dual damascene structure is provided for use in the wiring-line structures of multi-level interconnects in integrated circuit. In this dual damascene structure, low-K (low dielectric constant) dielectric materials are used to form both the di-electric layers and the etch-stop layers between the metal interconnects in the IC device. With this feature, the dual damascene structure can prevent high parasite capacitance to occur therein that would otherwise cause large RC delay to the signals being transmitted through the metal interconnects and thus degrade the performance of the IC device. With the dual damascene structure, such parasite capacitance can be reduced, thus assuring the performance of the IC device.

An bonding pad structure has a passivation layer over a copper layer having a pad window to expose a portion of the copper layer, a barrier layer conformal to a profile of the pad window, and an aluminum pad located in the pad window. The metal layer can be an aluminum, aluminum alloy or aluminum dominated layer for providing a better adhesion property between the copper layer and the bonding wire.
