Abstract:
A device and fabrication techniques are described that employ wafer-level packaging techniques for fabricating semiconductor devices that include a pad defined contact. In implementations, the wafer-level package device that employs the techniques of the present disclosure includes a substrate, a passivation layer, a top metal contact pad, a thin film with a via formed therein, a redistribution layer structure configured to contact the top metal contact pad, and a dielectric layer on the thin film and the redistribution layer structure. In implementations, a process for fabricating the wafer-level package device that employs the techniques of the present disclosure includes processing a substrate, forming a passivation layer, depositing a top metal contact pad, forming a thin film with a via formed therein, forming a redistribution layer structure in the via formed in the thin film, and forming a dielectric layer on the thin film and the redistribution layer structure.
