Abstract
The present invention relates to a field of photonic integrated circuits, which provides a semiconductor device. In some embodiments, the semiconductor device includes: a PIC chip including a conductive structure in a via; a first electronic integrated circuit chip (i.e., first EIC chip) arranged on a first surface of the PIC chip; a second electronic integrated circuit chip (i.e., second EIC chip) arrange on a second surface of the PIC chip; wherein the first EIC chip is electrically connected to the second EIC chip through the conductive structure in the via of the PIC chip. The semiconductor device of the present invention optimizes wiring of the PIC chip and can suppress a voltage drop caused by quite a long wire, optimizing a package structure.
