Abstract

Devices and methods for forming a chip package structure including a package substrate, a first adhesive layer attached to a top surface of the package substrate, and a beveled stiffener structure attached to the package substrate. The beveled stiffener structure may include a bottom portion including a tapered top surface, in which a bottom surface of the bottom portion is in contact with the first adhesive layer, a second adhesive layer attached to the tapered top surface, and a top portion including a tapered bottom surface, in which the tapered bottom surface is in contact with the second adhesive layer. The tapered top surface and the tapered bottom surface have a taper angle between 5 degrees and 60 degrees with respect to a top surface of the package substrate.
