Metallization Process

This process produces a thin film metal layer that will serve as the required conductor pattern for the interconnection of the various components on the chip Another use of metallization is to produce metalized areas called bonding pads around the periphery of the chip to produce metalized areas for the bonding of wire leads from the package to the chip.
