Abstract:
A method for manufacturing a semiconductor device, comprising:forming an opening in an interlayer dielectric films formed on a semiconductor substrate; forming a conductive coating made of a material containing aluminum over the interlayer dielectric film and covering said opening, the conductive coating including one or more conductive films formed successively at respective film formation temperatures; and cooling the formed conductive coating from the film formation temperature at which a last one of the successively formed conductive films is formed, without heating the conductive coating after the step of forming the conductive coating, the cooling being sufficiently slow to alleviate thermal stress generated in the formed conducive coating, wherein the step of forming the conductive coating and the step of cooling the conductive coating are continuously performed in an apparatus having a plurality of chambers that are maintained under a reduced pressure state.
