Megasonic Acoustic Surface Treatment Process for Enhanced Copper Electrodeposition in Via Interconnects

Press/Media: Research


For more than four years, Merlin Circuit Technology Ltd (MCT), in Deeside, North Wales, has been working in collaboration with Heriot-Watt University (HWU) in Edinburgh, Scotland, on a UK government project funded by the Engineering and Physical Sciences Research Council (EPSRC), looking to improve HD PCB manufacturing capability through enhancements to the electrodeposition of copper using high frequency acoustic, applied within a copper plating bath. This article outlines some of the key findings from this project.
