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 6):
The method of  claim 1 , wherein the forming the MEOL structure comprises:\n forming a first MEOL layer and a second MEOL layer which are made of the same material, wherein the first and second MEOL layers are formed by different recipes, such that the first MEOL layer has an etch resistance property which is different from that of the second MEOL layer.
