  • Publication number: 20040067634
    Abstract: In order to avoid a faulty pattern resulting from a photoresist tail being formed due to a step difference of an upper hard mask layer when a dual hard mask layer is used, a planarization layer is formed following patterning of the upper hard mask layer. In this manner, a photoresist pattern is formed without the creation of a photoresist tail. Alternatively, a single hard mask layer and a planarization layer are substituted for the dual lower hard mask layer and an upper hard mask layer, respectively. In this manner, it is therefore possible to form a photoresist pattern without a photoresist tail being formed during photolithographic processes. In order to prevent formation of a facet, the planarization layer is thickly formed or, alternatively, the hard mask layer is etched using the photoresist pattern.

  • Publication number: 20040058538
    Abstract: 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.

  • Publication number: 20020106891
    Abstract: A method of fabricating a semiconductor device having a low dielectric constant is disclosed. According to the method, a silicon oxycarbide layer is formed, treated with plasma, and patterned. The silicon oxycarbide layer is formed by a coating method or a CVD method such as a PECVD method. Treating the silicon oxycarbide layer with plasma is performed by supplying at least one gas selected from a group of He, H2, N2O, NH3, N2, O2 and Ar. It is desirable that plasma be applied at the silicon oxycarbide layer in a PECVD device by an in situ method after forming the silicon oxycarbide layer. In a case in which a capping layer is further stacked and patterned, it is desirable to treat with H2-plasma. Even in a case in which an interlayer insulation is formed of the silicon oxycarbide layer and a coating layer of an organic polymer group for a dual damascene process, it is desirable to perform the plasma treatment before forming the coating layer.
