    摘要: Provided are a semiconductor device having a self-aligned contact plug and a method of fabricating the semiconductor device. The semiconductor device includes conductive patterns, a first interlayer insulating layer, a first spacer, a second interlayer insulating layer, and a contact plug. In each conductive pattern, a conductive layer and a capping layer are sequentially deposited on an insulating layer over a semiconductor substrate. The first interlayer insulating layer fills spaces between the conductive patterns and has a height such that when the first interlayer insulating layer is placed on the insulating layer, the first interlayer insulating layer is lower than a top surface of the capping layer but higher than a top surface of the conductive layer. The first spacer surrounds the outer surface of the capping layer on the first interlayer insulating layer. The second interlayer insulating layer covers the first interlayer insulating layer, the capping layer, and the first spacer and has a planarized top surface. The contact plug passes through the second interlayer insulating layer, the first interlayer insulating layer, and the insulating layer between the conductive patterns, is electrically connected to the semiconductor substrate, has an outerwall surrounded by a second spacer, and is self-aligned with the capping layer.

    摘要: Methods are provided for fabricating semiconductor devices having capacitors, which prevent lower electrodes of the capacitors from breaking or collapsing and which provide increased capacitance of the capacitors. For instance, a method includes forming a first insulating layer on a semiconductor substrate, forming a first hole in the first insulating layer, forming a contact plug in the first hole, forming a second insulating layer having a landing pad, wherein the landing pad contacts an upper surface of the contact plug, forming an etch stop layer on the landing pad and the second insulating layer, forming a third insulating layer on the etch stop layer, forming a third hole through the third insulating layer and etch stop layer to expose the landing pad, selectively etching the exposed landing pad, forming a lower electrode on the selectively etched landing pad, and then forming a capacitor by forming a dielectric layer and an upper electrode on the lower electrode.
