Encapsulated solder TSV insertion interconnect

Abstract:

A method of coupling a first semiconductor device to a second semiconductor device can include encapsulating solder balls on a first surface of a first substrate of the first semiconductor device with an encapsulant material. In some embodiments, the method includes removing a portion of the encapsulant material and a portion the solder balls to form a mating surface. The method can include reflowing the solder balls. In some embodiments, the method includes inserting exposed conductive pillars of the second semiconductor device into the reflowed solder balls.
