The present disclosure provides a method for forming patterns in a semiconductor device. The method includes providing a substrate and a patterning-target layer over the substrate; patterning the patterning-target layer to form a main pattern; forming a middle layer over the patterning-target layer and a hard mask layer over the middle layer; patterning the hard mask layer to form a first cut pattern; patterning the hard mask layer to form a second cut pattern, a combined cut pattern being formed in the hard mask layer as a union of the first cut pattern and the second cut pattern; transferring the combined cut pattern to the middle layer; etching the patterning-target layer using the middle layer as an etching mask to form a final pattern in the patterning-target layer. In some embodiments, the final pattern includes the main pattern subtracting an intersection portion between main pattern and the combined cut pattern.

Provided is a semiconductor device and methods of forming the same. The semiconductor device includes a substrate having source/drain regions and a channel region between the source/drain regions; a gate structure over the substrate and adjacent to the channel region; source/drain contacts over the source/drain regions and electrically connecting to the source/drain regions; and a contact protection layer over the source/drain contacts. The gate structure includes a gate stack and a spacer. A top surface of the source/drain contacts is lower than a top surface of the spacer, which is substantially co-planar with a top surface of the contact protection layer. The contact protection layer prevents accidental shorts between the gate stack and the source/drain regions when gate vias are formed over the gate stack. Therefore, gate vias may be formed over any portion of the gate stack, even in areas that overlap the channel region from a top view.
