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 4):
The method for manufacturing dual damascene structures of  claim 3 , wherein in said etch process said etching selectivity between said capping layer and said sacrificial layer are different, so that said etch process also remove all of said sacrificial layer in said via hole.
