摘要: The present invention provides a method for fabricating a patterned structure in a semiconductor device, which includes the following processes. First, a target layer, a first mask and a first patterned mask are sequentially formed on a substrate. Then, a first etching process is performed to form a plurality of characteristic structures on the substrate, wherein each of the characteristic structures comprises a patterned first mask and a patterned target layer. A second patterned mask is formed on the substrate, wherein the second patterned mask covers a portion of the characteristic structures and exposes a predetermined region. A second etching process is performed to fully eliminate the characteristic structures within the predetermined region. Finally, a third etching process is performed to fully eliminate the target layer not covered by the patterned first mask.
