Abstract: A semiconductor device has a substrate and plurality of first bumps formed over the substrate in an array. An array of second bumps is formed over the substrate on at least two sides of the first bumps. An electrical component is disposed over the first bumps. A package structure is disposed over the substrate and electrical component. The package structure has a horizontal member and legs extending from the horizontal member to form a cavity. The package structure is coupled to the array of second bumps. The package structure includes a material to operate as a heat sink or shielding layer. The shielding layer makes ground connection through the array of second bumps. The first bumps and second bumps have a similar height and width to form in the same manufacturing step. A protective layer, such as conductive epoxy, is disposed over the array of second bumps.

Abstract: An embodiment of the present invention allows mold compound to flow underneath a substrate where the mold compound will remain in place until the process of mold formation is completed. The mold compound of the package will penetrate all available cavities where the mold compound will remain in place and harden. After hardening, the mold compound surrounding a mold anchor will support an anchored area.

Abstract: A method and assembly are provided for anchoring the heat spreader of a PBGA package to the substrate thereof as part of the PBGA package. These anchor features are provided over the surface of the substrate of the PBGA package. The anchor features align with openings created in the heat spreader stand-off, thus allowing for quick and reliable positioning and anchoring of the heat spreader over the surface of the substrate of the package.

Abstract: A new method is provided for the creation of a mold cap. The mold cap anchoring feature of the invention is designed and incorporated from the start of the design and fabrication of the substrate. Various design options of the mold anchor of the invention can be implemented. The mold anchor of the invention allows the mold compound to flow underneath the substrate where the mold compound will remain in place until the process of mold formation is completed. The mold compound of the package will penetrate all available cavities surrounding and being accessible from the mold anchor of the invention where the mold compound will remain in place and harden. After hardening, the mold compound surrounding the mold anchor will support the anchored area.

Abstract: A PBGA package is provided. The heat spreader interfaces with the substrate with the standoff of the heat spreader. The stand-off of the heat spreader is provided with an opening, the stand-off of the heat spreader is aligned with the substrate of the PBGA package by means of a copper pad that is provided over a second surface of the substrate. A solder bump is further provided over the surface of the copper pad. Thermally conductive solder is deposited over the opening of the heat spreader and over the copper pad. If the heat spreader stand-off is aligned with contact pads, thermally conductive epoxy is deposited over the contact pads.
