Disclosed herein is an apparatus for continuously producing and pelletizing gas hydrates. The apparatus includes a gas supply unit, a water supply unit and a reactor. Gas and water are respectively supplied from the gas supply unit and the water supply unit into the reactor. The gas and water react with each other in the reactor. The reactor includes a dual cylinder unit which forms a gas hydrate in such a way as to squeeze a slurry of reaction water formed by the reaction between the gas and water. The dual cylinder unit includes an upper cylinder, a lower cylinder and a connection pipe which connects the upper cylinder to the lower cylinder. The connection pipe has passing holes through which the reaction water in the reactor flows into and out of the connection pipe.

Provided are a metal line, a method of forming the same, and a display using the same. To increase resistance of a metal line having a multilayered structure of CuO/Cu and prevent blister formation, a plasma treatment is performed using a nitrogen-containing gas and a silicon-containing gas or using a hydrogen or argon as and the silicon-containing gas. Accordingly, a plasma treatment layer such as a SiNx or Si layer is thinly formed on the copper layer, thereby preventing an increase in resistance of the copper layer and also preventing blister formation caused by the damage of a copper oxide layer. Consequently, it is possible to improve the reliability of a copper line and thus enhance the reliability of a device.

A flash memory device has improved erasable characteristics and device reliability. The flash memory device includes a semiconductor substrate and heavily doped impurity regions formed spaced apart from one another by a predetermined distance in the semiconductor substrate in a first direction. First and second isolation regions are formed spaced apart from each other by a second predetermined distance on the semiconductor substrate, in a second direction which is preferably at a right angle to the first direction. Each of the floating gates are formed between the first and second isolation regons and between the heavily doped impurity regions. The control gate lines are formed between the first and second isolation regions, and over the floating gates in the same direction as the first and second isolation regions. An erase gate line is formed to have a narrower width than the floating gate, and is formed over the floating gate, preferably at a right angle to the control gate line.
