Disclosed is a method for fabricating a semiconductor device; and more particularly, to a method for fabricating a plurality of contact plugs capable of preventing a self-aligned contact (SAC) fail during forming a plurality of contact holes formed by using a SAC etching process and a defect generation during performing a plug isolation process. The present invention prevents a Pinocchio defect that is a fundamental problem caused by the chemical mechanical polishing (CMP) process and simplifies a subsequent cleaning process performed according to the particles. Accordingly, it is possible to develop products with a high quality and a high speed and to replace the CMP process having a high unit process cost with an etch back process, thereby providing an effect of increasing a price competitiveness.
