Abstract:
1. A method comprising: forming an inter-layer dielectric over a release layer; forming a first plurality of redistribution lines comprising first portions extending into the inter-layer dielectric, and second portions over the inter-layer dielectric; attaching a first device die to a top surface of the inter-layer dielectric or top surfaces of the first portions of the first plurality of redistribution lines through a die-attach film; forming first Z-interconnects over and electrically coupled to the first plurality of redistribution lines; after the forming the first Z-interconnects, molding the first device die and the first Z-interconnects in a first polymer-comprising material; and forming a second plurality of redistribution lines electrically coupling to the first device die, wherein the first plurality of redistribution lines and the second plurality of redistribution lines are on opposite sides of the first Z-interconnects.
