    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. A first insulating layer is disposed over the semiconductor die. A first via is formed in the first insulating layer over a contact pad of the semiconductor die. A first conductive layer is disposed over the first insulating layer and in the first via. A second insulating layer is disposed over a portion of the first insulating layer and first conductive layer. An island of the second insulating layer is formed over the first conductive layer and within the first via. The first conductive layer adjacent to the island is devoid of the second insulating layer. A second conductive layer is disposed over the first conductive layer, second insulating layer, and island. The second conductive layer has a corrugated structure. A width of the island is greater than a width of the first via.

    Abstract: A semiconductor device has a substrate with a plurality of active semiconductor die disposed over a first portion of the substrate and a plurality of non-functional semiconductor die disposed over a second portion of the substrate while leaving a predetermined area of the substrate devoid of the active semiconductor die and non-functional semiconductor die. The predetermined area of the substrate devoid of the active semiconductor die and non-functional semiconductor die includes a central area, checkerboard pattern, linear, or diagonal area of the substrate. The substrate can be a circular shape or rectangular shape. An encapsulant is deposited over the active semiconductor die, non-functional semiconductor die, and substrate. An interconnect structure is formed over the semiconductor die. The absence of active semiconductor die and non-functional semiconductor die from the predetermined areas of the substrate reduces bending stress in that area of the substrate.
