Variable cross-section plated mushroom with stud for bumping |
摘要 |
An improved bump fabrication process is described that produces a larger diameter/taller solder ball than with a standard mushroom by forming an elongated mushroom having a short axis in the direction of adjacent connection mushrooms and an elongated axis orthogonal to the short axis. The increased larger volume solder when reflowed produces the larger diameter/taller bolder ball bump.
