    摘要: The present invention comprises a method for forming a semiconducting device including the steps of providing a layered structure including a substrate, a low diffusivity layer of a first-conductivity dopant; and a channel layer; forming a gate stack atop a protected surface of the channel layer; etching the layered structure selective to the gate stack to expose a surface of the substrate, where a remaining portion of the low diffusivity layer provides a retrograded island substantially aligned to the gate stack having a first dopant concentration to reduce short-channel effects without increasing leakage; growing a Si-containing material atop the recessed surface of the substrate; and doping the Si-containing material with a second-conductivity dopant at a second dopant concentration. The low diffusivity layer may be Si1-x-yGexZy, where Z can be carbon (C), xenon (Xe), germanium (Ge), krypton (Kr), argon (Ar), nitrogen (N), or combinations thereof.

    摘要: The invention relates to a semiconductor structure and method of manufacturing and more particularly to a CMOS device with at least one embedded SiGe layer in the source/drain region of the PFET, and at least one embedded SiGe layer in the channel region of the NFET. In one embodiment, the structure of the invention enhances the electron mobility in the NFET device, and further enhances the hole mobility in the PFET device. Additionally, by using the fabrication methods and hence achieving the final structure of the invention, it is also possible to construct a PFET and NFET each with embedded SiGe layers on the same substrate.

    摘要: High performance (surface channel) CMOS devices with a mid-gap work function metal gate are disclosed wherein an epitaxial layer is used for a threshold voltage Vt adjust/decrease for the PFET area, for large Vt reductions (˜500 mV), as are required by CMOS devices with a mid-gap metal gate. The present invention provides counter doping using an in situ B doped epitaxial layer or a B and C co-doped epitaxial layer, wherein the C co-doping provides an additional degree of freedom to reduce the diffusion of B (also during subsequent activation thermal cycles) to maintain a shallow B profile, which is critical to provide a surface channel CMOS device with a mid-gap metal gate while maintaining good short channel effects. The B diffusion profiles are satisfactorily shallow, sharp and have a high B concentration for devices with mid-gap metal gates, to provide and maintain a thin, highly doped B layer under the gate oxide.
