    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: A gated diode structure and a method for fabricating the gated diode structure on an SOI substrate (10), uses a relaxed liner (34') that is derived from a stressed liner (34) that is typically used within the context of a field effect transistor formed simultaneously with the gated diode structure. The relaxed liner is formed incident to treatment, such as ion implantation treatment, of the stressed liner (34). The relaxed liner provides improved gated diode ideality in comparison with the stressed liner, absent any gated diode damage that may occur incident to stripping the stressed liner from the gated diode structure while using a reactive ion etch method.
