Claim:
1. A semiconductor device structure, comprising: a first integrated circuit package comprising at least one integrated circuit device mounted on a first substrate, the first substrate having a bottom surface and a top surface opposite the bottom surface, the top surface in contact with a molding compound overlying the first substrate, a plurality of package on package connectors extending from the bottom surface of the first substrate, and a cavity formed on the bottom surface and extending into the first substrate, the package on package connectors arranged spaced from the cavity, the first substrate having a first thickness from the bottom surface to the top surface over the package on package connectors and a second thickness from the bottom surface to the top surface over the cavity, the first thickness being greater than the second thickness; and a second integrated circuit package comprising at least another integrated circuit device mounted on a second substrate, a plurality of lands on an upper surface of the second substrate coupled to the plurality of package on package connectors, and a plurality of external connectors extending from a bottom surface of the second integrated circuit package; wherein at least a portion of the at least another integrated circuit device extends into the cavity on the bottom surface of the first substrate.
