Abstract: A semiconductor device has a substrate with a stiffening layer disposed over the substrate. The substrate has a circular shape or rectangular shape. A plurality of semiconductor die is disposed over a portion of the substrate while leaving an open area of the substrate devoid of the semiconductor die. The open area of the substrate devoid of the semiconductor die includes a central area or interstitial locations among the semiconductor die. The semiconductor die are disposed around a perimeter of the substrate. An encapsulant is deposited over the semiconductor die and substrate. The substrate is removed and an interconnect structure is formed over the semiconductor die. By leaving the predetermined areas of the substrate devoid of semiconductor die, the warping effect of any mismatch between the CTE of the semiconductor die and the CTE of the encapsulant on the reconstituted wafer after removal of the substrate is reduced.

Abstract: A semiconductor device has a semiconductor die mounted to a carrier. An encapsulant is deposited over the semiconductor die and carrier. The carrier is removed. A first insulating layer is formed over the encapsulant and semiconductor die. First vias are formed through the first insulating layer to expose contact pads of the semiconductor die. A first conductive layer is formed over the first insulating layer and into the first vias to electrically connect to the contact pads of the semiconductor die. A second insulating layer is formed over the first insulating layer and first conductive layer. Second vias are formed through the second insulating layer by laser direct ablation and aligned or offset with the first vias to expose the first conductive layer. A second conductive layer is formed over the second insulating layer and into the second vias. Conductive vias can be formed through the encapsulant.

Abstract: A semiconductor device has a first build-up interconnect structure formed over a substrate. The first build-up interconnect structure includes an insulating layer and conductive layer formed over the insulating layer. A vertical interconnect structure and semiconductor die are disposed over the first build-up interconnect structure. The semiconductor die, first build-up interconnect structure, and substrate are disposed over a carrier. An encapsulant is deposited over the semiconductor die, first build-up interconnect structure, and substrate. A second build-up interconnect structure is formed over the encapsulant. The second build-up interconnect structure electrically connects to the first build-up interconnect structure through the vertical interconnect structure. The substrate provides structural support and prevents warpage during formation of the first and second build-up interconnect structures. The substrate is removed after forming the second build-up interconnect structure. A portion of the insulating layer is removed exposing the conductive layer for electrical interconnect with subsequently stacked semiconductor devices.

Abstract: A semiconductor device has a semiconductor die mounted to a carrier. An encapsulant is deposited over the semiconductor die and carrier. The carrier is removed. A first insulating layer is formed over a portion of the encapsulant within an interconnect site outside a footprint of the semiconductor die. An opening is formed through the first insulating layer within the interconnect site to expose the encapsulant. The opening can be ring-shaped or vias around the interconnect site and within a central region of the interconnect site to expose the encapsulant. A first conductive layer is formed over the first insulating layer to follow a contour of the first insulating layer. A second conductive layer is formed over the first conductive layer and exposed encapsulant. A second insulating layer is formed over the second conductive layer. A bump is formed over the second conductive layer in the interconnect site.
