Abstract

Presented is an integrated circuit packaged at the wafer level wafer (also referred to as a wafer level chip scale package, WLCSP), and a method of manufacturing the same. The WLCSP comprises a die having an electrically conductive redistribution layer, RDL, formed above the upper surface of the die, the RDL defining a signal routing circuit. The method comprises the steps of: depositing the electrically conductive RDL so as to form an electrically conductive ring surrounding the signal routing circuit; and coating the side and lower surfaces of the die with an electrically conductive shielding material.
