摘要： A method of forming fine metal interconnect patterns includes forming an insulating film on a substrate, forming a plurality of mold patterns with first spaces therebetween on the insulating film, such that the mold patterns have a first layout, forming metal hardmask patterns in the first spaces by a damascene process, removing the mold patterns, etching the insulating film through the metal hardmask patterns to form insulating film patterns with second spaces therebetween, the second spaces having the first layout, and forming metal interconnect patterns having the first layout in the second spaces by the damascene process.

摘要： A method of forming hard mask employs a double patterning technique. A first hard mask layer is formed on a substrate, and a first sacrificial pattern is formed on the first hard mask layer by photolithography. Features of the first sacrificial pattern are spaced from one another by a first pitch. A second hard mask layer is then formed conformally on the first sacrificial pattern and the first hard mask layer so as to delimit recesses between adjacent features of the first sacrificial pattern. Upper portions of the second hard mask layer are removed to expose the first sacrificial pattern, and the exposed first sacrificial pattern and the second sacrificial pattern are removed. The second hard mask layer and the first hard mask layer are then etched to form a hard mask composed of residual portions of the first hard mask layer and the second hard mask layer. A fine pattern of a semiconductor device, such as a trench isolation region or a pattern of contact holes, can be formed using the hard mask as an etch mask.

摘要： Disclosed is an E-beam lithography system for synchronously irradiating surfaces of a plurality of substrates. The E-beam lithography system may include a loading unit loading and unloading substrates, an alignment chamber aligning the substrates, a transfer chamber transferring the substrates from the loading unit or chambers, a lithography chamber radiating one or more electron beams onto the substrates, and a vacuum chamber creating a vacuum in the chambers. A stage may be installed in the lithography chamber such that the substrates may be mounted on the stage and radiated with one or more electron beams.
