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 3):
The composite carrier as claimed in  claim 1 , wherein\n one of the top substrate and the bottom substrate is made of a material selected from the group consisting of:\n Invar having a coefficient of thermal expansion (CTE) around 1 ppm, \n silicon (Si) having a CTE around 3 ppm, \n cemented carbide having a CTE around 5.5 ppm, \n aluminum (Al) having a CTE around 7.2 ppm, \n titanium (Ti) having a CTE around 8.6 ppm, \n copper clad laminate (CCL) having a CTE around 1\u02dc17 ppm, \n stainless steel having a CTE around 10\u02dc18.0 ppm, \n Alloy 42 having a CTE around 4.8 ppm, \n aluminum nitride (AlN) having a CTE around 5 ppm, and \n zirconia (ZrO 2 ) having a CTE around 10.5 ppm, and \n the other of the top substrate and the bottom substrate is made of a material selected from the group consisting of:\n Invar having a coefficient of thermal expansion (CTE) around 1 ppm, \n silicon (Si) having a CTE around 3 ppm, \n cemented carbide having a CTE around 5.5 ppm, \n aluminum (Al) having a CTE around 7.2 ppm, \n titanium (Ti) having a CTE around 8.6 ppm, \n glass having a CTE around 0\u02dc10 ppm, \n copper clad laminate (CCL) having a CTE around 1\u02dc17 ppm, \n stainless steel having a CTE around 10\u02dc18.0 ppm, \n Alloy 42 having a CTE around 4.8 ppm, \n Aluminum oxide (Al 2 O 3 ) having a CTE around 7 ppm, \n aluminum nitride (MN) having a CTE around 5 ppm, and \n zirconia (ZrO 2 ) having a CTE around 10.5 ppm.
