Abstract:
A stiffener apparatus for reducing warpage of an integrated circuit package during heating and cooling are provided. The stiffener apparatus includes an IC substrate configured to receive an IC die on a top side of the IC substrate. The stiffener apparatus includes a primary stiffener ring adhered to the top side of the IC substrate and defining an opening in a region of the IC die such that the primary stiffener ring surrounds the region of the IC die. The primary stiffener ring defines a plurality of grooves. The stiffener apparatus includes a secondary stiffener ring having a plurality of catches configured to engage with the plurality of grooves to removably attach the secondary stiffener ring to the primary stiffener ring on a side of the primary stiffener ring opposite the IC substrate. A method of using a stiffener apparatus during a manufacturing operation is also provided.

Claim (Index 20):
The method of  claim 11 , wherein the secondary stiffener ring has a thickness in a direction normal to the top surface of the IC substrate that is thicker than a thickness of the primary stiffener ring.
