摘要:
Provided are semiconductor devices that include an active pattern on a substrate, first and second gate electrodes on the active pattern and arranged in a first direction relative to one another and a first source/drain region in a first trench that extends into the active pattern between the first and second gate electrodes. The first source/drain region includes a first epitaxial layer that is configured to fill the first trench and that includes at least one plane defect that originates at a top portion of the first epitaxial layer and extends towards a bottom portion of the first epitaxial layer.

摘要:
A semiconductor device may have a structure that prevents or reduces an etching amount of certain portions, such as a part of a source/drain region. Adjacent active fins may be merged with a blocking layer extending between adjacent the source/drain region. The blocking layer may be of a material that is relatively high-resistant to the etchant.
摘要:
A non-volatile memory device includes a dielectric layer between a charge storage layer and a substrate. Free bonds of the dielectric layer can be reduced to reduce/prevent charges from leaking through the free bonds and/or from being trapped by the free bonds. As a result, data retention properties and/or durability of a non-volatile memory device may be enhanced.

A refrigerator comprises: an inner case that forms a storage space; a plurality of fixing members coupled to the inner case so as to be protruding to the storage space, for preventing a foaming agent applied to a rear surface of the inner case from leaking to the storage space; and a guide rail fixedly-coupled to the fixing members, and to which a storage means is slidably coupled. Since components for slidably coupling a storage means to the inner case are simplified and an assembly process is facilitated, a production cost is reduced and a productivity is enhanced. Furthermore, the components for slidably coupling the storage means to the inner case are firmly coupled to the inner case, and a foaming agent is prevented from leaking to inside of the inner case, thereby enhancing the reliability of the product.
摘要:
In a method of forming an insulation structure, at least one oxide layer is formed on an object by at least one oxidation process, and then at least one nitride layer is formed from the oxide layer by at least one nitration process. An edge portion of the insulation structure may have a thickness substantially the same as that of a central portion of the insulation structure so that the insulation structure may have a uniform thickness and improved insulation characteristics. When the insulation structure is employed as a tunnel insulation layer of a semiconductor device, the semiconductor device may have enhanced endurance and improved electrical characteristics because a threshold voltage distribution of cells in the semiconductor device may become uniform.

A method for transmitting a call signal through a digital channel while in an analog area is provided which allows for enhanced speech and transmission quality while in the analog area. When a call is originated in an analog area, a mobile communication terminal scans a most recently used (MRU) table to locate a digital channel which matches a digital channel available in the analog area. If there is a match, the call is placed through the available digital channel. If none of the digital channels in the MRU table matches the available digital channel, then the call is placed through an analog channel.
摘要:
Methods of forming a semiconductor device having stacked structures include forming a first semiconductor structure on a substrate and forming a first interlayer insulating layer on the substrate. The first interlayer insulating layer has a substantially level upper face. A semiconductor layer is formed on the first interlayer insulating layer and a first gate insulation layer is formed on the semiconductor layer at a processing temperature selected to control damage to the first semiconductor structure. A second semiconductor structure is formed on the first gate insulation layer.

A method of forming an oxide layer on a semiconductor substrate includes thermally oxidizing a surface of the substrate to form an oxide layer on the substrate, and then exposing the oxide layer to an ambient including predominantly oxygen radicals to thereby thicken the oxide layer. Related methods of fabricating a recessed gate transistor are also discussed.
