    摘要: A method of forming a dual damascene structure on a substrate having a dielectric layer already formed thereon. In one embodiment the method includes depositing a first hard mask layer over the dielectric layer and depositing a second hard mask layer on the first hard mask layer, where the second hard mask layer is an amorphous silicon layer. Afterwards, formation of the dual damascene structure is completed by etching a metal wiring pattern and a via pattern in the dielectric layer and filling the etched metal wiring pattern and via pattern with a conductive material.
