Abstract:
PURPOSE: A photomask treating method is provided to improve the efficiency of a photo mask process by correcting a line width of light shielding pattern which is out of a predetermined critical dimension. CONSTITUTION: In a photomask treating method, a substrate is prepared(S110). A light-shielding layer and a photoresist pattern are formed on the substrate(S120). A light-shield pattern is formed on the substrate(S130). The photoresist pattern is removed(S140). It is determines whether the line width of the light-shield pattern is out of a predetermined critical dimension(S150). The line width of the light-shield pattern is corrected(S170).
Abstract:
A method for fabricating a mask for semiconductor device manufacture is provided to manufacture the mask having the high reliability by precisely controlling the shape and the size of the pattern. A mask layout(100) comprises the first region(200) and the second region(300). The second region is comprised of a pattern region(310), an aided exposure region(320), and a beam blocking region(330). The aided exposure region contacts with the end of the pattern region. The beam blocking region divides the aided exposure region from the first region. The beam blocking region of the concave type contacts with three sides of the aided exposure region of the rectangular shape. The pattern region contacts with the exposed side of the aided exposure region. The electron beam is irradiated to the first region and the aided exposure region.
Abstract:
A photolithography apparatus including a mirror for correcting an aberration of an optical system and a mirror including an aberration correcting unit are provided to expend the lifetime of the photolithography apparatus by directly compensating the aberration. A light source(110) generates light. Illumination mirrors(120a-120d) transmit the light generated from the light source. A photo mask(130) receives the light transmitted from the illumination mirrors to form an optical pattern image. An optical illumination system(100) includes projection mirrors(120e-120h). The projection mirror transmits the optical pattern image formed from the photo mask to a pupil surface(140). A mirror compensates an aberration of the optical illumination system. The mirror is located on a conjugate plan optically corresponding to the pupil surface. The mirror includes an aberration compensating unit therein.
