    Abstract: Electronic device package technology is disclosed. In one example, an electronic device package can include a bottom surface and a side surface extending from the bottom surface. The side surface can be oriented at a non-perpendicular angle relative to the bottom surface. In another example, an electronic device package can include a top planar surface having a first area, a bottom planar surface having a second area, and a side surface extending between the top surface and the bottom surface. The second area can be larger than the first area. In yet another example, an electronic device package can include a substrate defining a plane, an electronic component disposed on the substrate, and a layer of material disposed about a lateral side of the electronic component. The layer of material can be oriented at an angle of less than 90 degrees relative to the plane.

    Abstract: Semiconductor packages with electromagnetic interference (EMI) shielding structures and a method of manufacture therefor is disclosed. In some aspects, a shielding structure can serve as an enclosure formed by conductive material or by a mesh of such material that can be used to block electric fields emanating from one or more electronic components enclosed by the shielding structure at a global package level or local and/or compartment package level for semiconductor packages. In one embodiment, wire and/or ribbon bonding can be used to fabricate the shielding structure. For example, one or more wire and/or ribbon bonds can go from a connecting ground pad on one side of the package to a connecting ground pad on the other side of the package. This can be repeated multiple times at a pre-determined pitch necessary to meet the electrical requirements for shielding, e.g. less than or equal to approximately one half the wavelength of radiation generated by the electronic components being shielded.
