    摘要: Correcting light intensity for photolithography may include irradiating light having a first light intensity distribution through a photo mask having a mask pattern to a photosensitive layer on a wafer to form a first pattern corresponding to the mask pattern. A distribution of critical dimensions of the first pattern corresponding to the mask pattern may be determined, and a second light intensity distribution may be determined based on a relation between the first light intensity distribution and the distribution of critical dimensions of the first pattern. Then, light having the second light intensity distribution may be irradiated. Related systems are also discussed.

    摘要: In a method of manufacturing a non-volatile semiconductor memory device that includes a first region having a first gate structure and a second region having a second gate structure, the first gate structure may include a tunnel oxide layer pattern, a first conductive layer pattern, a dielectric layer pattern and a second conductive layer pattern. A first photoresist pattern may be formed on the second conductive layer pattern to form a source line which may be formed in a region of the first area by implanting impurities. A second photoresist pattern may be formed on a hard mask layer in the second region of the substrate to form a hard mask pattern on a third conductive layer. The second gate structure having substantially vertical sidewalls may be formed in the second area by etching the third conductive layer using the hard mask pattern.

    摘要: Disclosed is a method for manufacturing a semiconductor device by employing a dual damascene process. After a first insulation film including a conductive pattern is formed on a substrate, at least one etch stop film and at least one insulation film are alternatively formed on the first insulation film. A via hole for a contact or a trench for a metal wiring is formed through the insulation film, and then the via hole or the trench is filled with a filling film including a water-soluble polymer. After a photoresist film is coated on the filling film, the photoresist film is patterned to form a photoresist pattern and to remove the filling film. The DOF and processing margin of the photolithography process for forming the photoresist pattern can be improved because the photoresist film can have greatly reduced thickness due to the filling film.

    摘要: A method of forming fine patterns in a semiconductor device through a double photo lithography process. A layer to be etched and a hard mask layer are sequentially formed on a semiconductor substrate. A first photo resist pattern is formed on the hard mask layer. A first hard mask layer pattern is formed by etching the hard mask layer using the first photo resist pattern. After the first photo resist pattern is removed, a second photo resist pattern is formed on the resultant structure. A second hard mask layer pattern is formed by etching the first hard mask layer pattern using the second photo resist pattern. The layer to be etched is then etched using the second hard mask layer pattern after the second photo resist pattern has been removed, resulting in patterns have line edges without rounding.

    摘要: A method for forming a minute pattern includes forming a mask layer on an object being patterned. The mask layer is patterned to form a first mask pattern having a first width larger than a predetermined width. The first mask pattern is thermally treated to form a second mask pattern having a second width smaller than the first width. A polymer layer is formed on the second mask pattern. The polymer layer reacts with the second mask pattern to form a hardened layer on a boundary surface between the polymer layer and the second mask pattern, thereby forming a third mask pattern having a third width substantially identical to the predetermined width. The limits of the present photolithography equipment are overcome. Also, a semiconductor device having a CD of below about 100 nm is manufactured.

    摘要: A method of forming the patterns of a semiconductor device uses a photomask employed therein is disclosed. In a semiconductor device having a first region where a plurality of first patterns are separated from each other by a first space and a plurality of second patterns having a larger size than that of the first patterns are separated from each other by a second space that is wider than the first space, the first and second regions being formed on the same layer, a fine gap for transmitting light is formed in a central portion of a mask pattern that corresponds to the second pattern on the photomask for patterning the first and second patterns to reduce the proximity effect. Lifting margin and bridge margin with respect to a pattern where the pattern pitch varies are improved through the use of the fine gap.
