Copper is touted as an alternative die attach material. This study investigates the main parameters of a pressure sintering process using micro-scale copper sinter material as well as the behavior of the interconnection during thermal cycling by measuring the die shear strength and evaluating the microstructure of sintered copper layer. It was found that at 300°C a sintered joint is formed within 2 min. Furthermore, thermal cycling in a liquid-to-liquid shock test showed that only a slight decreased in the measured bonding strength decreased within the first 2000 cycles, therefore, the test has been extended by a further 1000 cycles.
