WAFER LEVEL CHIP SCALE PACKAGE HAVING REROUTING LAYER AND METHOD OF MANUFACTURING THE SAME

摘要

A wafer level chip scale package capable of reducing parasitic capacitances between a rerouting and the metal wiring of a wafer, and a method for manufacturing the same are provided. An embodiment of the wafer level chip scale package includes a wafer arranged with a plurality of bonding pads and an insulating member formed on the wafer so that the bonding pads are exposed. A rerouting is further formed on the insulating member in contact with the exposed bonding pads and an external connecting terminal is electrically connected to a portion of the rerouting. Here, the insulating member overlapping the rerouting is provided with a plurality of spaces in which air is trapped.
