    • PURPOSE: An illumination control module, a diffraction illumination system and a photolithography system including the same are provided to improve productivity in various photolithography processes by applying one diffraction lighting system to various photolithography process. CONSTITUTION: An illumination control module(100) comprises an upper lens(110) and a lower lens(120). The upper lens has a swollen ring shape. The lower lens has a concave ring shape. The absolute value of a focus distance of the lower lens is different to that of the upper lens. The circular constant of the lower lens is same as that of the upper lens. The horizontal width of the lower lens is smaller than the that of the upper lens. The upper lens and lower lens are independently moved up and down.
    • 目的:提供照明控制模块,衍射照明系统和包括其的光刻系统,以通过将一个衍射照明系统应用于各种光刻工艺来提高各种光刻工艺中的生产率。 构成:照明控制模块(100)包括上透镜(110)和下透镜(120)。 上透镜有一个肿胀的环形。 下透镜具有凹环形状。 下透镜的对焦距离的绝对值与上镜头的绝对值不同。 下透镜的圆形常数与上透镜的圆形常数相同。 下透镜的水平宽度小于上透镜的水平宽度。 上透镜和下透镜独立上下移动。
