ABSTRACT:
A method of fabricating an integrated circuit is provided. A first gate dielectric portion is formed on a substrate in a first transistor region. The first gate dielectric portion includes a first high-permittivity dielectric material. The first gate dielectric portion has a first equivalent silicon oxide thickness. A second gate dielectric portion is formed on the substrate in a second transistor region. The second gate dielectric portion includes the first high-permittivity dielectric material. The second gate dielectric portion has a second equivalent silicon oxide thickness. The second equivalent silicon oxide thickness is different than the first equivalent silicon oxide thickness.
