摘要： A method is provided that includes first etching a substrate according to a first mask. The first etching forms a first etch feature in the substrate to a first depth. The first etching also forms a sliver opening in the substrate. The sliver opening may then be filled with a fill material. A second mask may be formed by removing a portion of the first mask. The substrate exposed by the second mask may be etched with a second etch, in which the second etching is selective to the fill material. The second etching extends the first etch feature to a second depth that is greater than the first depth, and the second etch forms a second etch feature. The first etch feature and the second etch feature may then be filled with a conductive metal.

摘要： A stack of a first metal line and a first dielectric cap material portion is formed within a line trench of first dielectric material layer. A second dielectric material layer is formed thereafter. A line trench extending between the top surface and the bottom surface of the second dielectric material layer is patterned. A photoresist layer is applied over the second dielectric material layer and patterned with a via pattern. An underlying portion of the first dielectric cap material is removed by an etch selective to the dielectric materials of the first and second dielectric material layer to form a via cavity that is laterally confined along the widthwise direction of the line trench and along the widthwise direction of the first metal line. A dual damascene line and via structure is formed, which includes a via structure that is laterally confined along two independent horizontal directions.

摘要： Embodiments of the present invention provide a method of forming borderless contact for transistor. The method may include forming a gate of a transistor, on top of a substrate, and spacers adjacent to sidewalls of the gate; forming a sacrificial layer surrounding the gate; causing the sacrificial layer to expand in height to become higher than the gate, the expanded sacrificial layer covering at most a portion of a top surface of the spacers and thereby leaving an opening on top of the gate surrounded by the spacers; filling the opening with a dielectric cap layer; replacing the expanded sacrificial layer with a dielectric layer; and forming a conductive stud contacting source/drain of the transistor, the conductive stud being isolated from the gate by the dielectric cap layer.

摘要： After formation of line openings in a hard mask layer, hard mask level spacers are formed on sidewalls of the hard mask layer. A photoresist is applied and patterned to form a via pattern including a via opening. The overlay tolerance for printing the via pattern is increased by the lateral thickness of the hard mask level spacers. A portion of a dielectric material layer is patterned to form a via cavity pattern by an etch that employs the hard mask layer and the hard mask level spacers as etch masks. The hard mask level spacers are subsequently removed, and the pattern of the line is subsequently transferred into an upper portion of the dielectric material layer, while the via cavity pattern is transferred to a lower portion of the dielectric material layer.
