    Abstract: A method of forming CMOS semiconductor (10) materials with PFET (16) and NFET (14) areas formed on a semiconductor substrate (12), covered respectively with a PFET (16) and NFET (14) gate dielectric layers composed of silicon oxide and different degrees of nitridation (18D and 18E) thereof. Provide a silicon substrate (12) with a PFET (16) area and an NFET (14) area and form PFET and NFET gate oxide layers thereover. Provide nitridation of the PFET gate oxide layer above the PFET area to form the PFET gate dielectric layer (42) above the PFET area with a first concentration level of nitrogen atoms in the PFET gate dielectric I ayer above the PFET area. Provide nitridation of the NFET gate oxide layer to form the NFET gate dielectric layer (40) above the NFET area with a different concentration level of nitrogen atoms from the first concentration level. The NFET gate dielectric layer (40) and the PFET gate dielectric layer (42) can have the same thickness.

    Abstract: The present invention provides a semiconducting structure including a substrate having an SOI region and a bulk-Si region, wherein the SOI region and the bulk-Si region have a same or differing crystallographic orientation; an isolation region separating the SOI region from the bulk-Si region; and at least one first device located in the SOI region and at least one second device located in the bulk-Si region. The SOI region has an silicon layer atop an insulating layer. The bulk-Si region further comprises a well region underlying the second device and a contact to the well region, wherein the contact stabilizes floating body effects. The well contact is also used to control the threshold voltages of the FETs in the bulk-Si region to optimized the power and performance of circuits built from the combination of the SOI and bulk-Si region FETs.
