Abstract:
Semiconductor integrated circuit devices having single crystalline thin film transistors and methods of fabricating the same are provided. The semiconductor integrated circuit devices include an interlayer insulating layer formed on a semiconductor substrate and a single crystalline semiconductor plug penetrating the interlayer insulating layer. A single crystalline semiconductor body pattern is provided on the interlayer insulating layer. The single crystalline semiconductor body pattern has an elevated region and contacts the single crystalline semiconductor plug. The method of forming the single crystalline semiconductor body pattern having the elevated region includes forming a sacrificial layer pattern covering the single crystalline semiconductor plug on the interlayer insulating layer. A capping layer is formed to cover the sacrificial layer pattern and the interlayer insulating layer, and the capping layer is patterned to form an opening which exposes a portion of the sacrificial layer pattern. Subsequently, the sacrificial layer pattern is selectively removed to form a cavity in the capping layer, and a planarized single crystalline semiconductor body pattern is formed to fill the cavity and the opening.
Abstract:
Provided are a semiconductor device and a manufacturing method thereof. A pair of adjacent gate structure can be formed on a substrate. Mask patterns exposing a portion located between the gate structures are formed. The substrate portion located between the gate structures can be etched using the mask patterns as an etch mask to form a pocket. First conduction type impurities can be implanted into the pocket to form a first impurity layer in a surface of the pocket. Second conduction type impurities can be implanted into the pocket to form a second impurity layer on the first impurity layer. The pocket can be filled with an insulating material. Accordingly, impurities having a type opposite to the type of source junction impurities are implanted into the pocket to reduce a potential barrier of a source junction. Consequently, punch-through generated between a source and a drain can be inhibited.

The dish washing machine includes a sump to receive and pump wash water, a sump housing forming an external appearance of the sump, a drainage pump coupled with the sump housing to discharge wash water and dirt, and a drainage channel disposed in the sump housing to guide wash water and dirt to the drainage pump.
Abstract:
A photo mask set for forming multi-layered interconnection lines and a semiconductor device fabricated using the same includes a first photo mask for forming lower interconnection lines and a second photo mask for forming upper interconnection lines. The first and second photo masks have lower opaque patterns parallel with each other and upper opaque patterns that overlap the lower opaque patterns. In this case, ends of the lower opaque patterns are located on a straight line that crosses the lower opaque patterns. As a result, when upper interconnection lines are formed using the second photo mask, poor photo resist patterns can be prevented from being formed despite the focusing of reflected light.
Abstract:
Methods of fabricating a semiconductor integrated circuit having thin film transistors using an SEG technique are provided. The methods include forming an inter-layer insulating layer on a single-crystalline semiconductor substrate. A single-crystalline semiconductor plug extends through the inter-layer insulating layer, and a single-crystalline epitaxial semiconductor pattern is in contact with the single-crystalline semiconductor plug on the inter-layer insulating layer. The single-crystalline epitaxial semiconductor pattern is at least partially planarized to form a semiconductor body layer on the inter-layer insulating layer, and the semiconductor body layer is patterned to form a semiconductor body. As a result, the semiconductor body includes at least a portion of the single-crystalline epitaxial semiconductor pattern. Thus, the semiconductor body has an excellent single-crystalline structure. Semiconductor integrated circuits fabricated using the methods are also provided.
Abstract:
Methods of forming a single crystal semiconductor thin film on an insulator and semiconductor devices fabricated thereby are provided. The methods include forming an interlayer insulating layer on a single crystal semiconductor layer. A single crystal semiconductor plug is formed to penetrate the interlayer insulating layer. A semiconductor oxide layer is formed within the single crystal semiconductor plug using an ion implantation technique and an annealing technique. As a result, the single crystal semiconductor plug is divided into a lower plug and an upper single crystal semiconductor plug with the semiconductor oxide layer being interposed therebetween. That is, the upper single crystal semiconductor plug is electrically insulated from the lower plug by the semiconductor oxide layer. A single crystal semiconductor pattern is formed to be in contact with the upper single crystal semiconductor plug and cover the interlayer insulating layer. The single crystal semiconductor pattern is grown by an epitaxy growth technique using the upper single crystal semiconductor plug as a seed layer, or by a solid epitaxy growth technique using the upper single crystal semiconductor plug as a seed layer.
