    摘要: A method for fabricating a conductive pattern including following steps is provided. A first conductive layer is formed on a substrate. A patterned hard mask layer is formed on the first conductive layer. A portion of the first conductive layer is removed to expose a portion of the substrate by using the patterned hard mask layer as a mask. A dielectric layer covering the patterned hard mask layer is formed on the substrate. A portion of the dielectric layer is removed to expose the patterned hard mask layer. The patterned hard mask layer is removed to form an opening in the dielectric layer. A second conductive layer is formed in the opening.

    摘要: A method for forming a contact window includes: a step of providing a substrate; a step of forming a patterned amorphous carbon layer or spin-on coating layer, in which a surface of the substrate is exposed at two sides of the amorphous carbon layer or spin-on coating layer; a step of forming an interlayer dielectric layer on the substrate; a step of removing a portion of the interlayer dielectric layer until the patterned amorphous carbon layer or spin-on coating layer is exposed; a step of removing the patterned amorphous carbon layer or spin-on coating layer to form an opening; and a step of filling the opening with a conductive material to form the contact window.
