Patent ID: 11114409

Abstract:
Examples herein relate to optoelectronic assemblies. In particular, implementations herein relate to an optoelectronic assembly formed via a chip on wafer on substrate (CoWoS) process. The optoelectronic assembly includes a substrate, an interposer, and an electronic integrated circuit (EIC). Each of the substrate, interposer, and EIC includes opposing first and second sides. The EIC is flip-chip assembled to the first side of the interposer, and the interposer with the EIC assembled thereto is flip-chip assembled to the first side of the substrate. An overmold layer extends over the first side of the interposer and encapsulates the EIC. The overmold layer includes a cavity such that a region of the first side of the interposer is exposed. An optical component is positioned within the cavity and coupled to the first side of the interposer.
