    摘要: Non-volatile memory devices include a tunnel insulating layer on a channel region of a substrate, a charge-trapping layer pattern on the tunnel insulating layer and a first blocking layer pattern on the charge-trapping layer pattern. Second blocking layer patterns are on the tunnel insulating layer proximate sidewalls of the charge-trapping layer pattern. The second blocking layer patterns are configured to limit lateral diffusion of electrons trapped in the charge-trapping layer pattern. A gate electrode is on the first blocking layer pattern. The second blocking layer patterns may prevent lateral diffusion of the electrons trapped in the charge-trapping layer pattern.

    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: A method of etching a platinum group metal film uses a gas mixture containing argon (Ar), oxygen (O2) and halogen gases and a method of forming a lower electrode of a capacitor uses the etching method. The gas mixture contains O2, Ar, and a third component, preferably a halogen, e.g., chlorine (Cl2) or hydrogen bromide (HBr). In the method of forming a lower electrode, a conductive film containing a metal belonging to a platinum (Pt) group is formed on a semiconductor substrate, a hard mask partially exposing the conductive film is then formed on the conductive film. Then, the exposed conductive film is dry-etched using the hard mask as an etching mask and a three-component gas mixture containing argon (Ar) and oxygen (O2), to form a conductive film pattern beneath the hard mask, and the hard mask is then removed.
