摘要： A method for forming a metal interconnection layer of a semiconductor device comprises forming a film including a material selective to a medium used in an ashing process on an interlayer insulating film. The method comprises transforming the film during the ashing process to form an interconnection pattern having a dual damascene structure. A dielectric material such as copper is deposited on the interconnection pattern, which is planarized through CMP, thereby forming a via contact having a single damascene structure without a recess therein.

摘要： A structurally improved fusing roller assembly based on the heat pipe principle is provided. The fusing roller assembly includes a fusing roller and a heat pipe coaxially mounted inside the fusing roller. A resistance heater is helically wound around the exterior cylindrical surface of the heat pipe, and rests between the inner cylindrical surface of the fusing roller and the exterior cylindrical surface of the heat pipe. The heat pipe is hermetically sealed with a quantity of a working fluid contained inside. The surface of fusing roller can be instantaneously heated up to a target fusing temperature. The fusing roller assembly can be heated up to a target fusing temperature within a shorter period of time without need for warm-up and stand-by period, so that power consumption decreases.

摘要： A structurally improved fusing roller assembly based on a heat pipe principle is provided. The fusing roller assembly includes a fusing roller that serves as a heat pipe, and a resistance heater and/or a halogen lamp inside the fusing roller, so that the surface of the fusing roller can be instantaneously heated up to a target fusing temperature. The fusing roller assembly can be heated up to a target fusing temperature within a shorter period of time without need for a warm-up period and a stand-by period, so that power consumption decreases.

摘要： Example embodiments of the present invention relate to a semiconductor device and a method of fabricating the same. Other example embodiments of the present invention relate to a semiconductor device having a metal silicide layer of a substrate and a barrier metal layer constituting a line layer and a method of fabricating the same. The semiconductor device may include a bar-type contact structure (e.g., a contact surface with an active region is bar shaped) and a dot-type contact structure (e.g., the contact surface is dot shaped). The bar-type contact structure may have a larger contact area with the active region. The bar-type contact structure may retard or prevent an ohmic contact layer, which is formed by the chemical combination of a barrier metal layer and a substrate between which a semiconductor layer is interposed, from being extended outside source/drain regions or being electrically shorted to a gate electrode. A contact hole exposing the substrate in a dot shape may be formed after the semiconductor layer is formed on the active region exposed in a bar shape.

摘要： A fusing roller of an electrophotographic image forming apparatus is provided. The fusing roller includes an internal pipe having enclosed both ends in which a vacuum state of predetermined pressure is maintained and a predetermined amount of working fluid is stored, a fusing portion installed to surround the internal pipe, and a heating portion comprised of a helical resistance heating coil which is installed between the fusing portion and the internal pipe and generates heat. The distance between windings becomes smaller at the ends of the fusing roller than at the center to compensate for the higher dissipation of heat at the ends of the fusing roller than at the center. The result is a fusing roller that can quickly heat up and that has a uniform temperature along the surface of the fusing roller from end to end.
