    摘要: A method of precisely inspecting the entire surface of a mask at a high speed in consideration of optical effects of the mask. The method includes designing a target mask layout for a pattern to be formed on a wafer, and extracting an effective mask layout using an inspection image measured from the target mask layout using an aerial image inspection apparatus as a mask inspection apparatus. The effective mask layout is input to a wafer simulation tool for calculating a wafer image to be formed on the wafer. Optical effects of the mask are detected by comparing the target mask layout with the effective mask layout.

    摘要: In an attenuated phase-shift mask (PSM) and a method of forming the same, a phase-shift layer and a light-shielding layer are sequentially stacked on a transparent substrate. The phase-shift layer and the light-shielding layer are sequentially removed from the substrate, to form a light-shielding pattern including a first opening and a phase-shift pattern including a second opening that is connected to the first opening and partially exposes the transparent substrate. Then, a transmitting portion is formed through the light-shielding pattern by partially removing the light-shielding pattern. The transmitting portion includes at least one portion of the phase-shift pattern on which a transmittance controller is formed. In one embodiment, the transmittance controller comprises a metal having a high absorption coefficient, and is formed through sputtering and diffusion processes. Accordingly, the intensity deviation between 0th and 1st order beams may be decreased, to thereby improve the processing margin of the exposure process.

    摘要: A method for inspecting a uniformity of CD (CD) of a photo mask pattern increases a production yield. The method obtains a CD by precisely measuring a photo mask by using, an electron microscope. Then, a measurement image having, a plurality of patterns formed in the photo mask is obtained by photographing the photo mask at a high speed through an optical microscope. A gray level based on the CD is calculated by capturing just a pattern area in the measurement image, and an estimated value and a correlation coefficient is obtained, when an open density of the measurement image is relatively low. Accordingly, a uniformity of CD can be confirmed more clearly in a measurement of high speed for a measurement image having a relatively low open density.
