Abstract:
1. A method of forming a smart card module with a plastic housing in which at least one semiconductor chip is arranged, the method comprising: producing a semiconductor wafer with semiconductor chips that are arranged in rows and columns, each semiconductor chip including an active upper surface that is provided with inner contact surfaces; separating the semiconductor wafer into individual semiconductor chips; fitting a mount apparatus with the individual semiconductor chips such that the individual semiconductor chips are positioned with their active upper surfaces on the upper surface of the mount apparatus; forming a common mount on the mount apparatus that comprises a plastic housing compound, wherein the semiconductor chips are embedded in the plastic housing compound; removing the mount apparatus; depositing a dielectric layer on a surface of the common mount that is at least partially defined by the active upper surfaces of the semiconductor chips; depositing at least one interposer metallization level on the dielectric layer; applying a contact metallization to an external contact surface of an outermost interposer metallization level, wherein the contact metallization is configured to facilitate contact data transmission; and separating the common mount into individual smart card modules.
