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 19):
The pre-clean apparatus of  claim 18 , further comprising:\n a spray head disposed within the chamber and connected to the line, wherein the spray head is configured to deliver the reduction agent from the vapor supply toward the semiconductor device held on the heating pedestal.
