Abstract
The invention is a method of preventing active metal circuit corrosion on a semiconductor device. Non-corrosive multi-layers of metals are applied over the entire surface of a semiconductor, and then the multi-layers are etched to separate the portions on device contacts from the portions on the non-contact areas of the semiconductor device.
