  • Patent number: 11677051
    Abstract: Embodiments described herein are directed towards enhanced systems and methods for applying underfill (UF) material to fill a gap between electrically coupled semiconductor devices in an integrated device. In some embodiments, uncured UF material may be applied to one edge of the gap, and capillary flow may be employed to distribute the uncured UF material into a first portion of the gap. To fill a second portion of the gap, accelerated motion may be employed. For example, the integrated device may be affixed to a centrifuge, and the centrifuge can be used to spin the integrated device to spread the uncured UF material further into the gap. In some embodiments, the accelerated motion may be employed to distribute the uncured UF material substantially uniformly within the gap. Once the uncured UF material has been spread out, one or more curing processes may be employed to cure the sandwiched UF material.
