Abstract:
A semiconductor device having a self-aligned contact, comprising:a semiconductor substrate having a self-aligned contact region and a non-self-aligned contact region; a self-aligned contact exposing a portion of the self-aligned contact region of the semiconductor substrate; a first insulating layer formed on the semiconductor substrate that exposes a portion of the semiconductor substrate corresponding to the self-aligned contact; a plurality of conductive patterns formed on the first insulating layer and spaced apart from each other; spacers formed on sidewalls of each of the plurality of conductive patterns; a second insulating layer formed over the first insulating layer that exposes the self-aligned contact in the self-aligned contact region, and formed over the entire surface of the first insulating layer in the non-self-aligned contact region; a third insulating layer formed between the second insulating layer and the spacer; a fourth insulating layer formed over the entire surface of the non-self-aligned contact region and formed on sidewalls of the spacers over the self-aligned contact region; and a fifth insulating layer formed on a portion of the fourth insulating layer over the non-self-aligned contact region.
