With options that include modules for frontside thick aluminum processing and backside metal deposition on ultra-thin wafers, Sigma fxP addresses challenges faced while scaling power physical vapor deposition (PVD) processes up to 300 mm wafer size. System deposits thick Al layers at rates >1.4 µm/min without any yield destroying whiskers or extrusions. It also carries thin wafer handling hardware and uses film deposition stress control to maximize throughput with minimal wafer bow.
