Abstract:
1. A device, comprising: a semiconductor device package having a semiconductor die with a first plurality of solder ball formations on a top surface of the semiconductor die, wherein the semiconductor die and the first plurality of solder ball formations are encapsulated within a protective molding material such that a top surface of each solder ball formation of the first plurality of solder ball formations is exposed and forms electrical contact surfaces on the top surface of the semiconductor device package, and wherein a second plurality of solder ball formations are applied onto the electrical contact surfaces; and an optical device package having a bottom surface with electrical contact surfaces, wherein a bottom surface of the optical device package is placed onto the top surface of the semiconductor device package such that electrical contact surfaces on the bottom surface of the optical device package make contact with associated ones of the second plurality of solder ball formations.
