Abstract
The present invention relates to die-die stacking structure and the method for making the same. The die-die stacking structure comprises a top die having a bottom surface, a first insulation layer covering the bottom surface of the top die, a bottom die having a top surface, a second insulation layer covering the top surface of the bottom die, a plurality of connection members between the top die and the bottom die and a protection material between the first insulation layer and the second insulation layer. The plurality of connection members communicates the top die with the bottom die. The protection material bridges the plurality of connection members to form a mesh layout between the first insulation layer and the second insulation layer. The structure and method of present invention at least provide more strength and stress buffer to resist die warpage and absorb thermal cycling stress, and then prevents the bump and dielectric materials in the die-die stacking structure from cracking caused by thermal stress or external mechanical stress.
