    Abstract: Disclosed is a method for fabricating a semiconductor device having at least one contact holes formed by employing a self-aligned contact (SAC) etching process. The contact holes are formed through the shortened number of sequential steps by using different process recipes. First, an anti-reflective coating (ARC) layer formed on a substrate structure prepared sequentially with a substrate, conductive structures, an etch stop layer and an inter-layer insulation layer is etched by employing an etch gas of CF4, O2, CO and Ar. Then, a portion of an inter-layer insulation layer is etched with use of an etch gas of CF4 and O2. The rest portion of the inter-layer insulation layer is subsequently etched by using a different etch gas of C4F6, CH2F2, O2 and Ar to thereby form at least one contact hole exposing the etch stop layer.

    Abstract: A method for fabricating a semiconductor device capable of preventing an inter-layer insulation layer from being damaged during a wet cleaning process. The method includes the steps of: forming a plurality of conductive structures on a substrate; forming an etch stop layer and a flowable insulation layer on the plurality of conductive structures subsequently; forming a photoresist pattern on the flowable insulation layer; forming a plurality of contact holes by etching the flowable insulation layer with use of the photoresist pattern as an etch mask, thereby exposing portions of the etch stop layer; forming at least one barrier layer on the contact holes; removing said at least one barrier layer and the etch stop layer disposed at each bottom portion of the contact holes to thereby expose the substrate; and cleaning the contact holes.
