    摘要: A method of fabricating a semiconductor device is disclosed. The exemplary method includes providing a substrate including a device layer and a sacrificial layer formed over the device layer and patterning the sacrificial layer thereby defining a cut pattern. The cut pattern of the sacrificial layer having an initial width. The method further includes depositing a mask layer over the device layer and over the cut pattern of the sacrificial layer. The method further includes patterning the mask layer thereby defining a line pattern including first and second portions separated by the cut pattern of the sacrificial layer and selectively removing the cut pattern of the sacrificial layer thereby forming a gap that separates the first and second portions of the line pattern of the mask layer. The method further includes patterning the device layer using the first and second portions of the line pattern of the mask layer.

    摘要: A method of forming a dual damascene includes forming first, second and third material layers sequentially over a substrate. The first, second and third material layers have first, second and third thicknesses, respectively. An opening is etched within the first material layer while a portion or all of the thickness of the third layer is simultaneously removed. The ratio of the depth of the opening and the thickness of the third material layer removed, correspond to an etch selectivity of the first material layer and the second material layer. The etching operation may be automatically terminated to produce the opening with a predetermined depth.
