摘要： A dual damascene process is disclosed. According to the dual damascene process of the present invention, a first recessed region through an intermetal dielectric layer is filled with a bottom protecting layer, and the bottom protecting layer and the intermetal dielectric layer are simultaneously etched to form a second recessed region that has a shallower depth and wider width than the first recessed region on the first recessed region by using an etch gas selectively etches the intermetal dielectric layer with respect to the bottom protecting layer. In other words, the etch selectivity ratio, the intermetal dielectric layer with respect to the bottom protecting layer, is preferably about 0.5 to about 1.5. Thus, it is possible to form a dual damascene structure without the formation of a byproduct or an oxide fence.

摘要： A method of forming a via contact structure using a dual damascene technique is provided. The method includes forming a lower interconnection line on a semiconductor substrate and sequentially forming an inter-metal dielectric layer and a hard mask layer on the semiconductor substrate having the lower interconnection line. The hard mask layer and the inter-metal dielectric layer are successivley patterned to form a via hole that exposes the lower interconnnection line. A sacrificial layer filling the via hole is formed on the hard mask layer. The sacrificial layer and the hard mask layer are patterned to form a first sacrificial layer pattern having an opening that crosses over the via hole and a second sacrificial layer pattern that remains in the via hole and to simultaneously form a hard mask pattern underneath the first sacrificial layer pattern. The inter-metal dielectric layer is partially etched using the hard mask pattern as an etching mask, thereby forming a trench in the inter-metal dielectric layer. The second sacrificial layer pattern is selectively removed to expose the the lower interconnection line.

摘要： A method of manufacturing a MIM capacitor having a bottom electrode is provided by forming a metal wire including copper on a substrate. After the metal wire is formed on the substrate, a dielectric film is formed on the metal wire. A top electrode film is formed on the dielectric film, and then the top electrode film is etched to form a top electrode. A hard metallic polymer formed during the etching of the top electrode film is removed using a mixture of an oxygen gas and a fluorocarbon based gas. The lifting of the thin films is effectively prevented, and the yield of the manufacturing process for manufacturing a MIM capacitor is increased. Additionally, the MIM capacitor has a uniform capacitance because the damage to the dielectric film is prevented, and the oxidation of the bottom electrode is also prevented.

摘要： A method of forming electric wiring using a dual damascene process wherein prevention of damage to a lower conductive pattern and low contact resistance may be achieved. A first insulation layer having a first trench filled with a conductive material is formed on a semiconductor substrate. A first etch stop layer, a second insulation layer and a third insulation layer are sequentially formed thereon. A capping layer is formed on the third insulation layer. A via hole is formed by selectively etching the capping layer, third insulation layer and second insulation layer. Then the capping layer is partially etched and a polymer layer is formed on the exposed first etch stop layer. A second trench is formed and the electric wiring is formed by filling a conductive material in a resulting structure. The polymer layer prevents damage to the conductive pattern by protecting the first etch stop layer.
