摘要:
Disclosed herein are a device having an embedded heat spreader and method for forming the same. A carrier substrate may comprise a carrier, an adhesive layer, a base film layer, and a seed layer. A patterned mask is formed with a heat spreader opening and via openings. Vias and a heat spreader may be formed in the pattern mask openings at the same time using a plating process and a die attached to the head spreader by a die attachment layer. A molding compound is applied over the die and heat spreader so that the heat spreader is disposed at the second side of the molded substrate. A first RDL may have a plurality of mounting pads and a plurality of conductive lines is formed on the molded substrate, the mounting pads may have a bond pitch greater than the bond pitch of the die contact pads.
