Films with thickness ranging from several ten μm to several mm are of great interest due to their application or necessity in highly integrated, small electric devices. In this work, we report the processing merit of a novel centrifugal sintering, which densifies metallic film by applying high pressure, in the absence of a pressure medium such as graphite bar in hot-pressing equipment. Cu thick film on SiO2 substrate has been prepared for studying the sintering behaviour. It is observed that the pores and cracks in the specimens were drastically removed, and then promoted its densification by centrifugal firing, compared with conventional firing.
