A complementary metal-oxide semiconductor (CMOS) device includes an NMOS thin body channel including a silicon epitaxial layer. An NMOS insulating layer is formed on a surface of the NMOS thin body channel and surrounds the NMOS thin body channel. An NMOS metal gate is formed on the NMOS insulating layer. The CMOS device further includes a p-channel metal-oxide semiconductor (PMOS) transistor including a PMOS thin body channel including a silicon epitaxial layer. A PMOS insulating layer is formed on a surface of and surrounds the PMOS thin body channel. A PMOS metal gate is formed on the PMOS insulating layer. The NMOS insulating layer includes a silicon oxide layer and the PMOS insulating layer includes an electron-trapping layer, the NMOS insulating layer includes a hole trapping dielectric layer and the PMOS insulating layer includes a silicon oxide layer, or the NMOS insulating layer includes a hole-trapping dielectric layer and the PMOS insulating layer includes an electron-trapping dielectric layer.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
