摘要:
A method of packaging a semiconductor die includes the use of an embedded ground plane or drop-in embedded unit. The embedded unit is a single, stand-alone unit with at least one cavity. The embedded unit is placed on and within an encapsulation area of a process mounting surface. The embedded unit may have different sizes and shapes and a number of different cavities that can be placed in a predetermined position on a substrate, panel or tape during processing of semiconductor dies that are embedded into redistributed chip package (RCP) or wafer level package (WFL) panels. The embedded unit provides the functionality and design flexibility to run a number of embedded units and semiconductor dies or components having different sizes and dimensions in a single processing panel or batch and reduces die drift, movement or skew during encapsulation and post-encapsulation cure.

A semiconductor device package having pre-formed and placed through vias and a process for making such a package is provided. One or more signal conduits are coupled to a lead frame that is subsequently embedded in an encapsulated semiconductor device package. The free end of signal conduits is exposed while the other end remains coupled to a lead frame. The signal conduits are then used as through package vias, providing signal-bearing pathways between interconnects or contacts on the bottom and top of the package and the leads.

Methods for forming electronic assemblies are provided. A device substrate having a plurality of electronic components embedded therein is provided. The device substrate is attached to a carrier substrate using an adhesive material. A plurality of cuts are formed through the device substrate to divide the device substrate into a plurality of portions. Each of the plurality of portions includes at least one of the electronic components. A force is applied to each of the plurality of portions in a direction away from the carrier substrate to remove the plurality of portions from the carrier substrate.

Fan-Out Wafer Level Packages (FO-WLPs) include double-sided molded package bodies in which first and second layers of components are embedded in a back-to-back relationship. In one embodiment, the FO-WLP fabrication method includes positioning a first microelectronic component carried by a first temporary substrate in a back-to-back relationship with a second microelectronic component carried by a second temporary substrate. The first and second components are overmolded while positioned in the back-to-back relationship to produce a double-sided molded package body. The first temporary substrate is then removed to expose a first principal surface of the package body at which the first component is exposed, and the second temporary substrate is likewise removed to expose a second, opposing principal surface of the package body at which the second component is exposed.

Fan-Out Wafer Level Packages (FO-WLPs) and methods for fabricating FO-WLPs containing Embedded Ground Planes (EGPs) and backside EGP interconnect structures are provided. In one embodiment, the method includes electrically coupling an EGP to a backside terminal of a first microelectronic device through a backside EGP interconnect structure. A molded package body is formed around the first microelectronic device, the EGP, and the EGP interconnect structure. The molded package body has a frontside at which the EGP is exposed. One or more Redistribution Layers are formed over the frontside of the molded packaged body and contain at least one interconnect line electrically coupled to the backside contact through the EGP and the backside EGP interconnect structure.

Embodiments of devices and methods of their manufacture include coupling first and second package surface conductors to a package surface with an intra-conductor insulating structure between the package surface conductors. The package surface conductors extend between and electrically couple sets of pads that are exposed at the package surface. Elongated portions of the package surface conductors are parallel with and adjacent to each other. The intra-conductor insulating structure is coupled between the package surface conductors along an entirety of the parallel and adjacent elongated portions, and the intra-conductor insulating structure electrically insulates the elongated portions of the package surface conductors from each other. Some embodiments may be implemented in conjunction with a stacked microelectronic package that includes sidewall conductors and an intra-conductor insulating structure between and electrically insulating the sidewall conductors from each other.

A method of forming a semiconductor device includes affixing a die to a heat sink to form a die and heat sink assembly and then placing the die and heat sink assembly on a support element. A semiconductor device includes a die and heat sink assembly disposed on a support element. The die and heat sink assembly is pre-assembled prior to being disposed on the support element.

A mechanism for accurate alignment of semiconductor package back side interconnect processing is provided. As semiconductor die are placed in position for an encapsulated panel, two or more alignment die having fiducial markings formed on the back, or non-active, side of those die are also placed in the panel. Once all the die and other components have been placed for the panel, the panel is encapsulated using an encapsulant. Excess encapsulant, if any, is removed by a process such as backgrinding. The back grinding process exposes the back side of the alignment die and the fiducial features on those alignment die. The fiducial features on the alignment die can then be used for alignment of backside processing operations on the panel.
