Abstract
A planarization method is disclosed to provide improved protection against cracking of the final passivation layer of integrated circuit devices. In one embodiment, such method includes final passivation of an integrated circuit device including at least one integrated circuit chip. Such final passivation includes the step of forming a layer of protective material over a top surface of the integrated circuit chip, and a subsequent step of planarizing such layer of protective material to obtain a protection layer having a substantially flat top surface.
