In typical semiconductor fabrication systems, chips are built up in large numbers on a single large wafer of semiconductor material, typically silicon. The individual chips are patterned with small pads of metal near their edges that serve as the connections to an eventual mechanical carrier. The chips are then cut out of the wafer and attached to their carriers, typically via wire bonding suc… ontario industrial \u0026 finishing skills centreWire bonding process of chip to PCBA.
