发明名称 Method for manufacturing a CMOS device having dual metal gate
摘要 A method for manufacturing a CMOS device includes providing a substrate having a first active region and a second active region defined thereon, forming a first conductive type transistor and a second conductive type transistor respectively in the first and the second active regions, performing a salicide process, forming an ILD layer, performing a first etching process to remove a first gate of the first conductive type transistor and to form an opening while a high-K gate dielectric layer is exposed in a bottom of the opening, and forming at least a first metal layer in the opening.
