摘要： In one embodiment, a method of processing a semiconductor substrate includes measuring a state of a processing chamber contamination before processing each semiconductor substrate. A process condition is then changed responsive to the state of chamber contamination to compensate for an influence of the state of chamber contamination on the process condition. If the change in process condition is outside of predetermined margin, a warning may be generated and the process may be stopped.

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： There are provided a method of forming a fine pattern of a semiconductor device using a silicon germanium sacrificial layer, and a method of forming a self-aligned contact using the same. The method of forming a self-aligned contact of a semiconductor device includes forming a conductive line structure having a conductive material layer, a hard mask layer, and a sidewall spacer on a substrate, and forming a silicon germanium (Si1-xGex) sacrificial layer, which has a height equal to or higher than a height of at least the conductive line structure, on an entire surface of the substrate. Then, a photoresist pattern for defining a contact hole is formed on the sacrificial layer, and the sacrificial layer is dry-etched, thereby forming a contact hole for exposing the substrate. A plurality of contacts for filling the contact hole are formed using polysilicon, and the remained sacrificial layer is wet-etched. Then, the region where the sacrificial layer is removed is filled with silicon oxide, thereby forming a first interlayer insulating layer.
