    Abstract: A method of forming dual metal CMOS transistors includes forming a first silicon layer on a gate dielectric layer provided on a substrate. A first metal layer is formed on the NMOS device areas. A second metal layer is formed on the PMOS device areas. These first and second metal layers consist of different metals. A second silicon layer is deposited on the first and second metal layers. A dry etching technique is performed to etch the second silicon layer, the first and second metal layers, and the first silicon layer. The dry etching stops on the gate dielectric layer, thereby forming gate electrodes. The first and second metal layers are reacted with the first and second silicon layers to form suicides in the gate electrodes.

    Abstract: A strained silicon MOSFET employs a high thermal conductivity insulating material in the trench isolations to dissipate thermal energy generated in the MOSFET and to avoid self-heating caused by the poor thermal conductivity of an underlying silicon germanium layer. The high thermal conductivity material is preferably silicon carbide, and the isolations preferably extend through the silicon germanium layer to contact an underlying silicon layer so as to conduct thermal energy from the active region to the silicon layer.

    Abstract: A dual-metal CMOS arrangement and method of making the same provides a substrate and a plurality of NMOS devices and PMOS devices formed on the substrate. Each of the plurality of NMOS devices and PMOS devices have gate electrodes. Each NMOS gate electrode includes a first silicide region on the substrate and a first metal region on the first silicide region. The first silicide region of the NMOS gate electrode consists of a first silicide having a work function that is close to the conduction band of silicon. Each of the PMOS gate electrodes includes a second silicide region on the substrate and a second metal region on the second silicide region. The second silicide region of the PMOS gate electrode consists of a second silicide having a work function that is close to the valence band of silicon.

    Abstract: The present invention relates to a method of processing selected surfaces in a semiconductor process chamber by creating a temperature differential between the selected surfaces and contacting the surfaces with a reactant that preferentially react with a surface at one end of the temperature differential relative to the other selected surface(s). More particularly, the invention relates to the use of nitrogen trifluoride (NF3) gas for in situ cleaning of cold wall process chambers such as Rapid thermal Chemical Vaporization (“RTCVD”) systems.
