ABSTRACT:
In manufacturing a semiconductor device, the first gettering layer is formed on the backside of a wafer, and the second gettering layers are then formed on the backside and side surfaces of a chip, allowing these gettering layers to serve as trapping sites against metallic contamination that generated after backside grinding in assembly processes.
