Abstract:
A method for manufacturing a semiconductor structure is provided. The method includes following steps. A MEOL structure is formed on an etch stop layer. A patterned masking layer with at least one opening is formed on the MEOL structure and a first etching process is performed to form a trench in the MEOL structure. A second etching process is performed to modify at least one sidewall of the trench.

Claim (Index 21):
A method for manufacturing a semiconductor structure, comprising:\n forming a middle end of line (MEOL) structure above a gate structure formed on a semiconductor substrate; performing a first etching process to the MEOL structure to form a first trench in the MEOL structure; and performing a second etching process to reshape the first trench as a second trench, wherein a width variation of the second trench is different than a width variation of the first trench.
