Abstract

A wafer-level-package device with peripheral side wall protection has a die, multiple conductive bumps, and a protection layer. The die has a top surface, a bottom surface, and a peripheral side wall. A cavity is formed on the peripheral side wall of the die and around the die. The multiple conductive bumps are mounted on at least one of the top surface and the bottom surface of the die. The protection layer covers the die, the cavity, and the multiple conductive bumps. The multiple conductive bumps are exposed from the protection layer.
