Abstract:
A method of making a semiconductor device comprising the steps of providing a first manufacturing line, providing a second manufacturing line, and forming a first redistribution interconnect structure using the first manufacturing line while forming a second redistribution interconnect structure using the second manufacturing line. The method further includes the steps of testing a first unit of the first redistribution interconnect structure to determine a first known good unit (KGU), disposing a known good semiconductor die (KGD) over the first KGU of the first redistribution interconnect structure, and dicing the first KGU and KGD from the first redistribution interconnect structure. The method further includes the steps of testing a unit of the second redistribution interconnect structure to determine a second KGU of the second redistribution interconnect structure and disposing first KGU of the first redistribution interconnect structure and the KGD over the second KGU of the second redistribution interconnect structure.

A first interconnect structure is formed over the first component and modular interconnect structure. A shielding layer is formed over the first component, modular interconnect structure, and first interconnect structure. The shielding layer provides protection for the enclosed semiconductor devices against EMI, RFI, or other inter-device interference, whether generated internally or from external semiconductor devices. The shielding layer is electrically connected to an external low-impedance ground point. A second component is disposed adjacent to the first component. The second component includes a passive device. An LC circuit includes the first component and second component. A semiconductor die is disposed adjacent to the first component. A conductive adhesive is disposed over the modular interconnect structure. The modular interconnect structure includes a height less than a height of the first component.
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.
