  • Patent number: 8993436
    Abstract: A method for fabricating a semiconductor device includes sequentially forming an etch stop film and an insulating film on a substrate including a lower pattern forming a conductive mask pattern including a first opening on the insulating film, forming a via-hole in the insulating film using the conductive mask pattern as an etch mask, the via-hole exposing the etch stop film, removing the conductive mask pattern, and forming a passivation film along a side wall of the via-hole after removing the conductive mask pattern.
    Type: Grant
