    Abstract: A semiconductor device has a semiconductor die and an encapsulant around the semiconductor die. A fan-in interconnect structure is formed over the semiconductor die while leaving the encapsulant devoid of the interconnect structure. The fan-in interconnect structure includes an insulating layer and a conductive layer formed over the semiconductor die. The conductive layer remains within a footprint of the semiconductor die. A portion of encapsulant is removed from over the semiconductor die. A backside protection layer is formed over a non-active surface of the semiconductor die after depositing the encapsulant. The backside protection layer is formed by screen printing or lamination. The backside protection layer includes an opaque, transparent, or translucent material. The backside protection layer is marked for alignment using a laser. A reconstituted panel including the semiconductor die is singulated through the encapsulant to leave encapsulant disposed over a sidewall of the semiconductor die.

    Abstract: A semiconductor device has a first conductive layer including a plurality of conductive traces. The first conductive layer is formed over a substrate. The conductive traces are formed with a narrow pitch. A first semiconductor die and second semiconductor die are disposed over the first conductive layer. A first encapsulant is deposited over the first and second semiconductor die. The substrate is removed. A second encapsulant is deposited over the first encapsulant. A build-up interconnect structure is formed over the first conductive layer and second encapsulant. The build-up interconnect structure includes a second conductive layer. A first passive device is disposed in the first encapsulant. A second passive device is disposed in the second encapsulant. A vertical interconnect unit is disposed in the second encapsulant. A third conductive layer is formed over second encapsulant and electrically connected to the build-up interconnect structure via the vertical interconnect unit.

    Abstract: A semiconductor device has a substrate including a plurality of conductive vias formed vertically and partially through the substrate. An encapsulant is deposited over a first surface of the substrate and around a peripheral region of the substrate. A portion of the encapsulant around the peripheral region is removed by a cutting or laser operation to form a notch extending laterally through the encapsulant to a second surface of the substrate opposite the first surface of the substrate. A first portion of the substrate outside the notch is removed by chemical mechanical polishing to expose the conductive vias. A second portion of the substrate is removed by backgrinding prior to or after forming the notch. The encapsulant is coplanar with the substrate after revealing the conductive vias. The absence of an encapsulant/base material interface and coplanarity of the molded substrate results in less over-etching or under-etching and fewer defects.
