    摘要: A multi-layered metal line of a semiconductor device includes a semiconductor substrate; a lower metal line formed on the semiconductor substrate and recessed on a surface thereof; an insulation layer formed on the semiconductor substrate including the lower metal line and having a damascene pattern for exposing a recessed portion of the lower metal line and for delimiting an upper metal line forming region; a glue layer formed on a surface of the recessed portion of the lower metal line; a first diffusion barrier formed on the glue layer to fill the recessed portion of the lower metal line; a second diffusion barrier formed on the glue layer and the first diffusion barrier; a third diffusion barrier formed on the second diffusion barrier and a surface of the damascene pattern; and an upper metal line formed on the third diffusion barrier to fill the damascene pattern.

    摘要: A semiconductor memory device is manufactured by: forming a hole by etching an interlayer insulation film formed over a semiconductor substrate; forming a barrier film over the interlayer insulation film including a surface of the hole; forming a first metal film over the barrier film so as to fill in the hole; forming a bit line contact plug in the hole by removing the first metal film and the barrier film so as to expose the interlayer insulation film; carrying out a gas treatment to a surface of the interlayer insulation film including the bit line contact plug so as to promote a growth of metal nucreation; forming a second metal film over the gas treated interlayer insulation film; and forming a bit line in contact with the bit line contact plug by etching the second metal film.
