摘要: A bilayer mask is utilized for etching a primary layer, which may be either an aluminum metallization layer or a dielectric layer. The bilayer mask includes both a thin resist layer and a metal imaging layer. The thin resist layer provides for high resolution patterning of the metal imaging layer. The metal imaging layer, in turn, provides for durability to withstand subsequent plasma etching of the underlying primary layer.
