Abstract:
An opto-electronic assembly is provided comprising a substrate (generally of silicon or glass) for supporting a plurality of interconnected optical and electrical components. A layer of sealing material is disposed to outline a defined peripheral area of the substrate. A molded glass lid is disposed over and bonded to the substrate, where the molded glass lid is configured to create a footprint that matches the defined peripheral area of the substrate. The bottom surface of the molded glass lid includes a layer of bonding material that contacts the substrate's layer of sealing material upon contact, creating a bonded assembly. In one form, a wafer level assembly process is proposed where multiple opto-electronic assemblies are disposed on a silicon wafer and multiple glass lids are molded in a single sheet of glass that is thereafter bonded to the silicon wafer.
