Abstract:
A composite carrier is disclosed for warpage management as a temporary carrier in semiconductor process. Warpage is reduced for a product, semi-product, or build-up layer processed on the temporary composite carrier which is peeled off the temporary carrier in a later step. The composite carrier comprises a top substrate and a bottom substrate, an adhesive layer is configured in between the top substrate and a bottom substrate. One of the embodiments discloses the top substrate of the composite carrier having a lower CTE and the bottom substrate of the composite carrier having a higher CTE.

Claim (Index 1):
A composite carrier for fabricating a build-up circuitry thereon, comprising:\n a polymer; a top substrate; a bottom substrate below the top substrate; and an adhesive layer between the top substrate and the bottom substrate, the adhesive layer bonding the top substrate to the bottom substrate; wherein\n each of the top substrate, the bottom substrate and the adhesive layer has\n top and bottom surfaces opposite to each other in a thickness direction of the composite carrier, and \n a side surface extending in the thickness direction and connecting the top and bottom surfaces, \n \n the top surface of the top substrate includes an area for semiconductor processing thereon, \n the polymer wraps around the side surface of each of the top substrate, the adhesive layer and the bottom substrate, \n the area for semiconductor processing on the top surface of the top substrate is free of the polymer, and \n in a cross-section taken in a plane perpendicular to the top surface of the top substrate, the polymer has an outer surface curved and convex outwardly away from the top substrate, the adhesive layer and the bottom substrate.
