摘要:
A microelectronic package may be fabricated having at least one microelectronic die attached to a microelectronic substrate, wherein the microelectronic substrate includes at least one notch formed in at least one side thereof. The microelectronic dice may be attached to a first surface of the microelectronic substrate and in electronic communication with a bond pad on a second surface of the microelectronic substrate with a bond wire which extends through the notch in the microelectronic substrate.

A package with improved solder joint reliability is disclosed. The package includes dummy beams with less rigidity and stiffness (relative to the die) that are placed in between the die and the substrate. The reduced rigidity and stiffness of the dummy beams significantly mitigates any die shadow effects on the solder joints. Also, because the die is attached to the dummy beams and does not directly contact the substrate itself, the die shadow effect from a rigid die is further reduced.

A computer memory module can include a molded layer disposed on a DRAM substrate. The molded layer can encapsulate a DRAM die and wire bonds that connect the DRAM die to the DRAM substrate, and can be shaped to include at least one cavity having a footprint sized to accommodate a system on chip (SOC) die. The DRAM module can attach to an SOC package so that the SOC die and the DRAM die are both positioned between the DRAM substrate and the SOC package, the DRAM substrate can form its electrical connections on only one side of the DRAM substrate, and the SOC die can fit at least partially into the cavity in the molded layer. This can reduce a package Z-height, compared to conventional DRAM packages in which the SOC die and the DRAM die are positioned on opposite sides of the DRAM substrate.

A packaged device (110) includes a substrate (114) and one or more contacts (118) disposed on a side of the substrate (114). Structures of the packaged device (110) define at least in part a recess region (120) that extends from the side of the substrate (114) and through the substrate (114), where one or more contacts (124) of a second hardware interface are disposed in the recess region (120). The one or more contacts (118) of the first hardware interface enable connection of the packaged device (110) to a printed circuit board. The one or more contacts (124) of the second hardware interface enable connection between one or more IC dies of the packaged device (110) and another IC die (150) that is a component of the packaged device (110) or of a different packaged device.

Some features pertain to a package (200) that includes a redistribution portion (204), a first die (202) coupled to the redistribution portion, a core layer (206) coupled to the redistribution portion, and an encapsulation layer (208) encapsulating the first die and the core layer. The redistribution portion includes a first dielectric layer (240). The core layer has a higher Young's Modulus than the encapsulation layer. In some implementations, the core layer includes a glass fiber (e.g., core layer is a glass reinforced dielectric layer). In some implementations, the core layer has a Young's Modulus of about at least 15 gigapascals (Gpa). In some implementations, the first die includes a front side and a back side, where the front side of the first die is coupled to the redistribution portion. In some implementations, the first dielectric layer is a photo imageable dielectric (PID) layer.

A semiconductor package includes a semiconductor chip mounted on a substrate, an insulating layer covering at least a portion of the semiconductor chip and including a thixotropic material or a hot melt material, and a shielding layer covering at least a portion of the semiconductor chip and the insulating layer. A method of manufacturing the semiconductor package includes forming an insulating layer and a shielding layer having a high aspect ratio by using a three-dimensional printer.

In described examples, a method (100) of lead frame surface modification includes providing (101) at least one pre-fabricated metal lead frame or package substrate (substrate) unit including a base metal having a die pad and a plurality of contact regions surrounding the die pad. An ink including a material that is a solid or a precursor for a solid that forms a solid upon a curing step or a sintering step that removes a liquid carrier is additive ly deposited (102) including onto at least one of (i) a region of the die pad and (ii) at one region of at least a first of the contact regions (first contact region). The ink is sintered or cured (103) to remove the liquid carrier so that a substantially solid ink residue remains.

A method of forming a semiconductor package includes providing a substrate having one or more conductive elements disposed therein. Each conductive element extends from a first surface of the substrate toward a second surface of the substrate extending beyond the second surface. The second surface comprises one or more substrate regions not occupied by a conductive element. A first die is attached within a substrate region, and the first die is coupled to at least one of the conductive elements. The first die may be coupled to at least one of the conductive elements by a wire bond connection. Alternatively, an RDL is formed over the second surface, and the first die is coupled to at least one conductive element through the RDL. A second die may be attached to an outer surface of the RDL, and the second die is electrically coupled to the first die through the RDL.
