    Abstract: A CMOS structure is formed on a semiconductor substrate that includes first and second regions having an nFET and a pFET respectively formed thereon. Each nFET and pFET device is provided with a gate, a source and drain, and a channel formed on the substrate. A high permittivity dielectric layer formed on top of the channel is superimposed to the permittivity dielectric layer. The pFET gate includes a thick metal nitride alloy layer or rich metal nitride alloy or carbon metal nitride layer that provides a controlled WF. Superimposed to the permittivity dielectric layer, the nFET gate is provided with a thin metal nitride alloy layer, enabling to control the WF. A metal deposition is formed on top of the respective nitride layers. The gate last approach characterized by having a high thermal budget smaller than 500° C. used for post metal deposition, following the dopant activation anneal.

  • Patent number: 8286895
    Abstract: A high bandwidth multi-stage microjet actuator. The actuator can produce relatively large amplitude flow disturbances over a broad range of frequencies. The disturbance frequency can be varied by altering the geometry of the device, altering the pressure ratio(s) within the device, and combinations of the two. The actuator has many potential applications, including noise abatement for jet aircraft, and flow control over a moving airfoil.
