Abstract

A method for wafer level packaging includes forming one or more die, forming a plated metal ring (PMR) on each die, forming a cover wafer (CW), the CW having one or more plated seal rings, forming a body wafer (BW), the BW having cavities and a metal layer on a first side of the BW, aligning a respective die to the CW so that a PMR on the respective die is aligned to a respective plated seal ring (PSR) on the CW, bonding the PMR on the respective die to the respective PSR, aligning the BW to the CW so that a respective cavity of the BW surrounds each respective die bonded to the CW and so that the metal layer on the BW is aligned with at least one PSR on the CW, and bonding the metal layer on the first side of the BW to the PSR on the CW. Each PMR has a first height and each PSR has a second height.
