Abstract:
A method for manufacturing dual damascene structures is provided with the steps of forming a via hole through a dielectric layer, forming a sacrificial layer on the dielectric layer filling up the via hole, performing an etch process through a photoresist to form a trench in the dielectric layer, wherein in the etch process the ratio of etching selectivity between the dielectric layer and the sacrificial layer is 1:1, and the trench and the via hole forms collectively a dual damascene recess.

Claim (Index 5):
The method for manufacturing dual damascene structures of  claim 1 , further comprising an etch stop layer between said substrate and said dielectric layer.
