Abstract:

An integrated device package is disclosed. The package can include a package substrate comprising a composite die pad having an upper surface and a lower surface spaced from the upper surface along a vertical direction. The composite die pad can include an insulator die pad and a metal die pad. The insulator die pad and the metal die pad can be disposed adjacent one another along the vertical direction. The substrate can include a plurality of leads disposed about at least a portion of a perimeter of the composite die pad. An integrated device die can be mounted on the upper surface of the composite die pad.
