Abstract
A technique for marking semiconductor devices with an identifiable mark or alphanumeric text yields a high-contrast, easily distinguishable mark on an electrical terminal of the device without impacting the device's breakdown voltage capability and without compromising the solderability and wire bondability of the terminal. This approach deposits the mark on the terminal as a patterned layer of palladium, which offers good contrast with the base metal of the terminal and maintains the solderability and bondability of the terminal.
