Synthesis of the plate-type Cu formate particles from CuO was accomplished through a wet reaction for 180 min. Cu, formed in situ in the bondline by pyrolysis of the formate during heating for the attachment, was sufficiently active to lead high-speed sintering within a carbon dioxide-hydrogen atmosphere derived from the pyrolysis, and the oxide layer on the Cu finish was reduced by the hydrogen. As a result, sinter bonding for 10 min formed a robust bonding with a shear strength approaching 27 MPa.}, type={Article}, title={Die Attachment Method on a Cu Finish by Pressure-Assisted Sinter Bonding in Air Using Cu Formate Paste}, URL={http://www.czasopisma.pan.pl/Content/116382/PDF/AMM-2020-3-15-Jong-Hyun%20Lee.pdf}, doi={10.24425/amm.2020.133217}, keywords={Die attach, Cu formate paste, Sinter bonding, Cu finish, shear strength}, }
