  • Patent number: 8669180
    Abstract: A method for forming semiconductor devices using damascene techniques provides self-aligned conductive lines that have an end-to-end spacing less than 60 nm without shorting. The method includes using at least one sacrificial hardmask layer to produce a mandrel and forming a void in the mandrel. The sacrificial hardmask layers are formed over a base material which is advantageously an insulating material. Another hardmask layer is also disposed over the base material and under the mandrel in some embodiments. Spacer material is formed alongside the mandrel and filling the void. The spacer material serves as a mask and at least one etching procedure is carried out to translate the pattern of the spacer material into the base material. The patterned base material includes trenches and raised portions. Conductive features are formed in the trenches using damascene techniques.
