    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: A metal interconnection of a semiconductor device, formed using a damascene process, has large grains and yet a smooth surface. First, a barrier layer and a metal layer are sequentially formed in an opening in an interlayer dielectric layer. A CMP process is carried out on the metal layer to form a metal interconnection remaining within the opening. Then, the metal interconnection is treated with plasma. The plasma treatment creates compressive stress in the metal interconnection, which stress produces hillocks at the surface of the metal interconnection. In addition, the plasma treatment process causes grains of the metal to grow, especially when the design rule is small, to thereby decrease the resistivity of the metal interconnection. The hillocks are then removed by a CMP process aimed at polishing the portion of the barrier layer that extends over the upper surface of the interlayer dielectric layer. Finally, a capping insulating layer is formed. The intentional forming of hillocks by the plasma treatment process at weak portions of the metal interconnection and the subsequent removal of the hillocks greatly reduces the possibility of any additional hillocks being produced at the surface of the metal interconnection, especially when the capping layer is formed.

    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 an image sensor device, an insulating interlayer structure having an opening is formed on a semiconductor substrate on which a semiconductor device and a photodetector are formed. An electrically conductive pattern, e.g, copper, fills the opening. A diffusion preventing pattern is formed only on the electrically conductive pattern. A color filter and a lens are also provided in an optical path of the photodetector. The diffusion preventing pattern is not disposed in the optical path of the photodetector. Thus, the image sensor device having the copper pattern may be easily manufactured.

    摘要: In a method of manufacturing a semiconductor device, a first insulation layer on the substrate is patterned to form a first opening having a first width. A lower electrode is formed along an inner contour of the first opening. A second insulation layer on the first insulation layer is patterned to form a second opening that has a second width greater than the first width and is connected to the first opening with a stepped portion. A dielectric layer is formed on the lower electrode in the first opening, a sidewall of the second opening and a first stepped portion between the first insulation layer and the second insulation layer, so that the electrode layer is covered with the dielectric layer. An upper electrode is formed on the dielectric layer. Accordingly, a leakage current between the lower and upper electrodes is suppressed.
