The Near-Field photolithography may make use of an elastomeric phase-shifting mask, or may employ surface plasmon technology, where a rotating cylinder surface comprises metal nano holes or nanoparticles. | 2010-05-20 |

20100123888 | EXPOSURE APPARATUS AND METHOD OF MANUFACTURING DEVICE - An apparatus, which scans an original and a substrate relative to light slit-shaped on the original and on the substrate, comprises an adjusting device configured to adjust a distribution of a width of the light slit-shaped, the width being a width in a scanning direction, the distribution being a distribution in a perpendicular direction perpendicular to the scanning direction, and a controller. The controller is configured to obtain information representing a relationship between a position on the substrate and a target dose, calculate a distribution of the target dose in the perpendicular direction with respect to each of the shot regions based on the relationship represented by the obtained information, and control the adjusting device so as to achieve the calculated distribution of the target dose with respect to each of the shot regions. | 2010-05-20 |
20100123889 | SUPER-RESOLUTION LITHOGRAPHY APPARATUS AND METHOD BASED ON MULTI LIGHT EXPOSURE METHOD - Disclosed herein is a super-resolution lithography apparatus and method based on a multiple light exposure method. The super-resolution lithography apparatus comprises a photographic medium having energy levels of a first ground state, a second ground state, a first excited state, a second excited state and a quenching state; a first light source inducing energy level transition between the first ground state and the first excited state of the photographic medium; a second light source inducing energy level transition between the second ground state and the first excited state of the photographic medium; and a third light source inducing energy level transition between the second ground state and the second excited state of the photographic medium. Accordingly, the resolution of lithography can be improved simply by using a photographic medium having a simple structure and conventional laser beams and increasing the number of exposure steps. Furthermore, a multiple photon absorber that is difficult to obtain, a medium having a complicated energy level and a high-efficiency quantum optical light are unnecessary, and thus economic efficiency is improved. | 2010-05-20 |
