Solder reaction-assisted crystallization of electroless Ni-P under bump metallization in the Si/SiO2/Al/Ni-P/63Sn-37Pb multilayer structure was analyzed using transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray, and electron probe microanalysis. The electroless Ni-P had an amorphous structure and a composition of Ni85P15 in the as-plated condition. Upon reflow, the electroless Ni-P transformed to Ni 3Sn4 and Ni3P. The crystallization of electroless Ni-P to Ni3P was induced by Ni depletion from electroless Ni-P to form Ni3Sn4. The crystallization kinetics were found to be diffusion-controlled
