A microelectronic package including a microelectronic die disposed within an opening in a microelectronic packaging core, wherein an encapsulation material is disposed within portions of the opening not occupied by the microelectronic die. Build-up layers of dielectric materials and conductive traces are then fabricated on the microelectronic die, the encapsulant material, and the microelectronic package core to form the microelectronic package.

摘要:
A microelectronic package including a microelectronic die having an active surface and at least one side. An encapsulation material is disposed adjacent the microelectronic die side(s). A portion of the encapsulation material is removed to expose a back surface of the microelectronic die which has a metallization layer disposed thereon. A protective layer is disposed on the metallization layer prior to encapsulation, such that when the portion of the encapsulation material is removed, the protective layer prevents the metallization layer from being damaged. After the portion of the encapsulation material is removed, the protective layer is removed and the metallization layer is exposed. A heat spreader may then be attached to the microelectronic die by abutting the heat spreader against the metallization layer and reflowing the metallization layer.

A semiconductor device having a multilayer laminate that includes a thermally stable, flexible polymer film, a semiconductor die, a molding compound, and a heat dissipation member. The die has an active surface and an inactive surface, in which the active surface includes a plurality of contacts. The molding compound contacts both the laminate and the die, but does not contact the die's active or inactive surfaces. The heat dissipation member contacts the die's inactive surface.

A chip-on-flex package which includes at least one moisture barrier layer to prevent metal corrosion and delamination of flex component layers. An exemplary microelectronic package includes a microelectronic die having an active surface and at least one side, wherein the microelectronic die active surface includes at least one contact. A flex component is attached by a first surface to the microelectronic die active surface. At least one conductive trace is disposed on a second surface of the flex component and extends through the flex component to contact at least one of the contacts. An encapsulation material is adjacent the microelectronic die side and a bottom surface of the flex component. A moisture barrier is disposed on the flex component and the conductive trace(s). A second moisture barrier may be disposed on the encapsulation material. A heat dissipation device may also be incorporated into the chip-on-flex package.

At least one conductive trace extends vertically adjacent the microelectronic die active surface and vertically adjacent the encapsulation material surface.
摘要:
A method of fabricating microelectronic dice by providing or forming a first encapsulated die assembly and a second encapsulated die assembly. Each of the encapsulated die assemblies includes at least one microelectronic die disposed in an encapsulation material. Each of the encapsulated die assemblies has an active surface and a back surface. The encapsulated die assemblies are attached together in a back surface-to-back surface arrangement. Build-up layers are then formed on the active surfaces of the first and second encapsulated assemblies, preferably, simultaneously. Thereafter, the microelectronic dice are singulated, if required, and the microelectronic dice of the first encapsulated die assembly are separated from the microelectronic dice of the second encapsulated die assembly.
