Zusammenfassung:Some embodiments relate to an electronic package. The electronic package includes a first die and a second die stacked onto the first die. A first encapsulant is positioned between the first die and the second die. The first encapsulant includes a first material that covers a first volume between the first die and the second die. A second encapsulant is positioned between the first die and the second die. The second encapsulant includes a second material that covers a second volume between the first die and the second die. The first material has a higher thermal conductivity than the second material, and the second material more effectively promotes electrical connections between the first die and the second die as compared to the first material.
