Zusammenfassung:Semiconductor devices and methods of forming the same are provided. A method according to the present disclosure includes forming a first wafer including a plurality of electronic integrated circuits (EICs), forming a second wafer including a plurality of photonic integrated circuits (PICs), bonding the first wafer to the second wafer to form a first stacked wafer. The bonding of the first wafer to the second wafer includes vertically aligning each of the plurality of the EICs with one of the plurality of the PICs.
