Abstract
A thin-layer metallization structure in which the final gold layer is deposited by evaporation with the surface onto which it is evaporated maintained at an elevated temperature. By evaporating the uppermost gold layer of the structure at an elevated substrate temperature, the gold atoms have a higher mobility, causing the deposited gold to spread over the edge of the structure and cover the otherwise exposed edges, including the edge at the copper interface.
