摘要:
A semiconductor device has a semiconductor die mounted to a carrier. A first encapsulant is deposited over the semiconductor die and carrier. A stiffening support member can be disposed over the carrier around the semiconductor die. A plurality of channels or recesses is formed in the first encapsulant. The recesses can be formed by removing a portion of the first encapsulant. Alternatively, the recesses are formed in a chase mold having a plurality of extended surfaces. A second encapsulant can be deposited into the recesses of the first encapsulant. The carrier is removed and an interconnect structure is formed over the semiconductor die and first encapsulant. The thickness of the first encapsulant provides sufficient stiffness to reduce warpage while the recesses provide stress relief during formation of the interconnect structure. A portion of the first encapsulant and recesses are removed to reduce thickness of the semiconductor device.

摘要:
A semiconductor device has a first semiconductor die including TSVs mounted to a carrier with a thermally releasable layer. A first encapsulant having a first coefficient of thermal expansion CTE is deposited over the first semiconductor die. The first encapsulant includes an elevated portion in a periphery of the first encapsulant that reduces warpage. A surface of the TSVs is exposed. A second semiconductor die is mounted to the surface of the TSVs and forms a gap between the first and second semiconductor die. A second encapsulant having a second CTE is deposited over the first and second semiconductor die and within the gap. The first CTE is greater than the second CTE. In one embodiment, the first and second encapsulants are formed in a chase mold. An interconnect structure is formed over the first and second semiconductor die.
