ABSTRACT:
A method of making a semiconductor structure includes trimming a patterned hard mask with a wet etch, wherein the hard mask is on a gate layer; and etching the gate layer. In making multiple structures on a semiconductor wafer, an average width of lines in the patterned hard mask is trimmed by at least 100 Å.
