Fine-Pitch Copper Pillar With Bond On Lead (BOL).


Fine pitch copper (Cu) pillar bump adoption has been growing in high-performance and low-cost flip chip packages. Higher input/output (I/O) density and very fine pitch requirements are driving very small feature sizes such as small bump on a narrow pad or bond-on-lead (BOL) interconnection, while higher performance requirements are driving increased current densities. Assembling such packages u... » read more
