摘要： A semiconductor die has a peripheral region around the die. An insulating layer is formed over the semiconductor die. A portion of the insulating layer and peripheral is removed to form a recess around the semiconductor die. A conductive layer is deposited over the insulating layer and recess. The conductive layer is electrically connected to contact pads on the semiconductor die and conforms to a step into the recess. A gap is created through the conductive layer and peripheral region around the semiconductor die. An insulating material is deposited in the gap. A portion of the insulating material is removed to form a through hole via (THV). A conductive material is deposited in the THV to form a conductive THV. The conductive THV is recessed with respect to a surface of the semiconductor die. The conductive THV is electrically connected to the conductive layer.

摘要： A semiconductor device has a temporary layer, such as a dam material or adhesive layer, formed over a carrier. A plurality of recesses is formed in the temporary layer. A first semiconductor die is mounted within the recesses of the temporary layer. An encapsulant is deposited over the first semiconductor die and temporary layer. The encapsulant extends into the recesses in the temporary layer. The carrier and temporary layer are removed to form recessed interconnect areas around the first semiconductor die. Alternatively, the recessed interconnect areas can be formed the carrier or encapsulant. Multiple steps can be formed in the recesses of the temporary layer. A conductive layer is formed over the first semiconductor die and encapsulant and into the recessed interconnect areas. A second semiconductor die can be mounted on the first semiconductor die. The semiconductor device can be integrated into PiP and Fi-PoP arrangements.

摘要： A semiconductor wafer contains a plurality of semiconductor die each having a peripheral area around the die. A first insulating layer is formed over the die. A recessed region with angled sidewall is formed in the peripheral area. A first conductive layer is formed over the first insulating layer outside the recessed region and further into the recessed region. A conductive pillar is formed over the first conductive layer within the recessed region. A second insulating layer is formed over the first insulating layer, conductive pillar, and first conductive layer such that the conductive pillar is exposed from the second insulating layer. A dicing channel partially through the peripheral area. The semiconductor wafer undergoes backgrinding to the dicing channel to singulate the semiconductor wafer and separate the semiconductor die. The semiconductor die can be disposed in a semiconductor package with other components and electrically interconnected through the conductive pillar.

摘要： A semiconductor device has a first semiconductor die mounted to a first contact pad on a leadframe or substrate with bumps. A conductive pillar is formed over a second semiconductor die. The second die is mounted over the first die by electrically connecting the conductive pillar to a second contact pad on the substrate with bumps. The second die is larger than the first die. An encapsulant is deposited over the first and second die. Alternatively, the conductive pillars are formed over the substrate around the first die. A heat sink is formed over the second die, and a thermal interface material is formed between the first and second die. An underfill material is deposited under the first semiconductor die. A shielding layer is formed between the first and second die. An interconnect structure can be formed over the second contact pad of the substrate.

摘要： A semiconductor device is made by providing a first semiconductor wafer having semiconductor die. A gap is made between the semiconductor die. An insulating material is deposited in the gap. A portion of the insulating material is removed to form a first through hole via (THV). A conductive lining is conformally deposited in the first THV. A solder material is disposed above the conductive lining of the first THV. A second semiconductor wafer having semiconductor die is disposed over the first wafer. A second THV is formed in a gap between the die of the second wafer. A conductive lining is conformally deposited in the second THV. A solder material is disposed above the second THV. The second THV is aligned to the first THV. The solder material is reflowed to form the conductive vias within the gap. The gap is singulated to separate the semiconductor die.
