Abstract
Missing thin film metallurgy on substrates is replaced during the manufacture of thin film electronic circuits. The process allows the missing thin film metallurgy, such as an input/output (I/O) pad or pads, to be replaced quickly and simply, without damaging the other I/O pads or thin film metallurgy already applied to the substrate. The process essentially uses lift-off technology without building a complete lift-off stencil.
