Patent ID: 7187068

Claim:
An apparatus comprising: a first substrate having a top surface and bottom surface; a set of one or more dies attached to the top surface of the first substrate, the one or more dies extending above the top surface a first distance; one or more interconnections formed on the top surface of the first substrate, the one or more interconnections extending above the top surface a second distance; a planar encapsulant disposed upon the top surface of the first substrate and extending above the top surface a third distance, the third distance greater than the first distance and less than the second distance such that the one or more dies are encapsulated and a portion of the one or more interconnections are exposed; and a second substrate above the first substrate, the second substrate having a bottom surface and one or more conductive pads formed on the bottom surface of the second substrate, each conductive pad extending from the bottom surface of the second substrate down to the second distance without extending to the third distance.
