摘要： A semiconductor device includes a lower copper line formed on a substrate, an interlayer insulating layer formed on the lower copper line, and an upper copper line formed on the interlayer insulating layer. A copper via contact extends through the interlayer insulating layer for electrically connecting the lower copper line and the upper copper line. A concave recess is formed within the lower copper line and is vertically aligned and arranged below the copper via contact. A patterned barrier layer is formed at a bottom portion of the concave recess, such that the lower copper line and the copper via contact are directly electrically connected at an interface along sides of the concave recess, without an intervening barrier layer.

摘要： Methods are provided for forming dual damascene interconnect structures using different conductor materials to fill via holes and line trenches. For example, a method for forming an interconnection structure includes depositing dielectric material on a semiconductor substrate and etching the dielectric material to form a dual damascene recess structure including a via hole and trench. A layer of first conductive material is then conformally deposited to fill the via hole with the first conductive material, and the layer of first conductive material is etched to remove the first conductive material from the trench and an upper region of the via hole below the trench. A layer of second conductive material is then deposited to fill the trench and upper region of the via hole with the second conductive material.

摘要： Methods of forming integrated circuit devices include patterning an electrically insulating layer to support dual-damascene interconnect structures therein. The steps of patterning the electrically insulating layer include using multiple planarization layers having different porosity characteristics. Forming an interconnect structure within an integrated circuit device may include forming an electrically insulating layer on a substrate and forming at least one via hole extending at least partially through the electrically insulating layer. The at least one via hole is filled with a first electrically insulating material having a first porosity. The filled at least one via hole is then covered with a second electrically insulating material layer having a second porosity lower than the first porosity. The second electrically insulating material layer is selectively etched back to expose a first portion of the first electrically insulating material in the at least one via hole. The electrically insulating layer is selectively etched to define a trench therein that exposes a second portion of the first electrically insulating material in the at least one via hole. The first electrically insulating material, which has a relatively high degree of porosity, is then removed from the at least one via hole. This removal step may be performed using a relatively mild ashing process because of the high porosity of the first electrically insulating material.

摘要： In a method of fabricating a semiconductor device by selectively forming a diffusion barrier layer, and a semiconductor device fabricated thereby, a conductive pattern and an insulating layer, which covers the conductive pattern, are formed on a semiconductor substrate. The insulating layer is patterned, thereby forming an opening for exposing at least a portion of the conductive pattern. Then, a diffusion barrier layer is formed on the semiconductor substrate having the opening, using a selective deposition technique. The diffusion barrier layer is formed to a thickness that is less on the exposed conductive pattern than the thickness of the diffusion barrier layer on the insulating layer exposed inside the opening. Then, the diffusion barrier layer is etched, thereby forming a recessed diffusion barrier layer. In this manner, metal atoms are prevented from being diffused from a metal plug filling the opening or a metal interconnect to the insulating layer.

摘要： In a method of manufacturing a semiconductor device, a pad including at least one insulating interlayer and at least one conductive wiring may be formed in a pad area of a substrate. At least one wiring may be formed adjacent to the conductive wiring. At least one insulation layer may be formed adjacent to the insulating interlayer. At least one crack preventing structure may be formed in the insulation layer. The crack preventing structure may continuously extend in the insulation layer and portions of the insulation layer may also be continuous. When a semiconductor device includes at least one crack preventing structure disposed adjacent to a pad, a degradation of the semiconductor chip caused by an external impact and/or a stress may be efficiently prevented by the crack preventing structure.
