Abstract
A method for fabricating a semiconductor structure includes the following steps. Decomposing a layout to first connection patterns and second connection patterns alternatively arranged with each other, where a to-be-split pattern is disposed between the first connection pattern and the second connection pattern; splitting the to-be-split pattern into a cutting portion and a counterpart cutting portion; forming a first photomask having a layout constructed by the first connection pattern and the cutting portion; forming a second photomask having a layout constructed by the second connection pattern and the counterpart cutting portion; transferring layouts of the first and second photomasks to a target layer to form connection patterns and a merged pattern, where the contour of the merged pattern is defined by the cutting portion and the counterpart cutting portion, and each end surface of the merged pattern comprises a recessed region and a protruded region.
