摘要: A bonded assembly includes an interposer including redistribution wiring interconnects and redistribution insulating layers and including recesses in corner regions. The recesses include surfaces that are recessed relative to a horizontal plane including a horizontal surface of the interposer. A least one semiconductor die is attached to the interposer through a respective array of solder material portions. An underfill material portion is located between the interposer and the at least one semiconductor die. The underfill material includes downward-protruding anchor portions that protrude downward from a horizontally-extending portion of the underfill material portion that laterally surrounds each array of solder material portions into the recesses.
