    摘要: One aspect of the invention provides a method of forming a semiconductor device (100). One aspect includes forming transistors (120, 125) on a semiconductor substrate (105), forming a first interlevel dielectric layer (165) over the transistors (120, 125), and forming metal interconnects (170, 175) within the first interlevel dielectric layer (165). A carbon-containing gas is used to form a silicon carbon nitride (SiCN) layer (180) over the metal interconnects (170, 175) and the first interlevel dielectric layer (165) within a deposition tool. An adhesion layer (185) is formed on the SiCN layer (180), within the deposition tool, by discontinuing a flow of the carbon-containing gas within the deposition chamber. A second interlevel dielectric layer (190) is formed over the adhesion layer (185).

    摘要: A method of manufacturing a semiconductor device includes the steps of providing a semiconductor substrate (202), forming a dielectric layer (204) over the semiconductor substrate (202), and etching a trench or a via (206) in the dielectric layer (204) to expose a portion of the surface of the semiconductor substrate (202). The method also includes the step of forming a conductive layer (212, 220) within in the trench or the via (206). The method further includes the steps of polishing a portion of the conductive layer (220) and annealing the conductive layer (212, 220) at a predetermined temperature. Moreover, the conductive layer (212, 220) also includes a dopant, and the dopant diffuses substantially to the surface of the top side of the conductive layer (212, 220) to form a dopant oxide layer (212a, 220a) when the conductive layer (212, 220) is annealed at the predetermined temperature and the dopant is exposed to oxygen.
