    摘要: This description relates to a method for fabricating an interconnection structure in a complementary metal-oxide-semiconductor (CMOS). The method includes forming a first opening in a dielectric layer over a substrate and partially filling the first opening with a second work-function metal layer, wherein a top surface of the second work-function metal layer is below a top surface of the first opening. The method further includes forming a second opening adjoining the first opening in the dielectric layer over the substrate and depositing a first work-function metal layer in the first and second openings, whereby the first work-function metal layer is over the second work-function metal layer in the first opening. The method further includes depositing a signal metal layer over the first work-function metal layer in the first and second openings and planarizing the signal metal layer.
