Semiconductor device with a self-aligned contact and a method of manufacturing the same

摘要

A semiconductor device having a self-aligned contact and a method for forming the same, including 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; a first insulating layer formed on the semiconductor substrate that exposes the self-aligned contact; conductive patterns formed on the first insulating layer and spaced apart from each other; spacers formed on sidewalls of each of the conductive patterns; a second insulating layer formed over the first insulating layer that exposes the self-aligned contact; a third insulating layer formed between the second insulating layer and the spacer; a fourth insulating layer formed over the non-self-aligned contact region and 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.
