A method divides a wafer into at least one chip. The chip includes internal metallic features. The dividing deposits at least one metallic substance on the outer surface of the chip. After so dividing the chip, the process exposes the chip to a heated ambient environment having a given pressure (e.g., less than one atmosphere). The environment comprises a chemical agent capable of bonding with the metallic substance. Additionally, wet chemical etch can be performed on the chip.
