Abstract:
In a method for manufacturing a semiconductor device, a substrate is provided. Various first metal layers are formed on the substrate. A dielectric structure with through holes is formed over the first metal layers. The through holes expose the first metal layers. A pre-clean operation is performed on the dielectric structure and the first metal layers by using an alcohol base vapor and/or an aldehyde base vapor as a reduction agent. Conductors are formed on the first metal layers. In forming the conductors, the through holes are filled with the conductors.

Claim (Index 9):
A method for manufacturing a semiconductor device, the method comprising:\n providing a substrate on which a plurality of first metal layers are formed; forming a plurality of dielectric layers stacked over the first metal layers sequentially; forming a plurality of through holes in the dielectric layers, wherein the through holes are formed to expose the first metal layers; performing a pre-clean operation to remove oxide film residues on the dielectric layers and the first metal layers, wherein performing the pre-clean operation uses an alcohol base vapor and/or an aldehyde base vapor as a reduction agent; and forming a plurality of conductors on the first metal layers, wherein forming the conductors comprises filling the through holes with the conductors respectively.
