Chromium dry etch
WebIn the dry etching of Cr film, an etchant gas containing a halide of hydrocarbon, for example, CCl 4, and oxygen is generally used. The etching mechanism involved in the … WebWe have investigated Cr film etching mechanism systematically in order to minimize CDU (CD Uniformity). As a result, employing our dry etching system ARESTM with optimized etch process we achieved an excellent CDU(3σ) (0.5nm with etch contribution). Cr film has been widely used not only for the light-shielding film at Cr Binary Mask but also as a hard …
