    摘要: A method for manufacturing a CMOS device having dual metal gate includes providing a substrate having at least two transistors of different conductive types and a dielectric layer covering the two transistors, planarizing the dielectric layer to expose gate conductive layers of the two transistors, forming a patterned blocking layer exposing one of the conductive type transistor, performing a first etching process to remove a portion of a gate of the conductive type transistor, reforming a metal gate, removing the patterned blocking layer, performing a second etching process to remove a portion of a gate of the other conductive type transistor, and reforming a metal gate.

    摘要: A method for fabricating a semiconductor structure is disclosed. A substrate with a first transistor having a first dummy gate and a second transistor having a second dummy gate is provided. The conductive types of the first transistor and the second transistor are different. The first and second dummy gates are simultaneously removed to form respective first and second openings. A high-k dielectric layer, a second type conductive layer and a first low resistance conductive layer are formed on the substrate and fill in the first and second openings, with the first low resistance conductive layer filling up the second opening. The first low resistance conductive layer and the second type conductive layer in the first opening are removed. A first type conductive layer and a second low resistance conductive layer are then formed in the first opening, with the second low resistance conductive layer filling up the first opening.
