The defect detecting pattern has a first pattern elongated in a first direction and a second pattern overlapping one end of the first pattern and elongated in a second direction different from the first direction. The first pattern and the second pattern are formed using electron beams (e-beam) diffracted by a same amplifier.

    摘要: In a method of estimating a PSF in the electron-beam lithography process, a linear resist test pattern may be formed on a substrate. A line response function (LRF) may be determined using a cross-sectional profile of the linear resist test pattern. A development rate distribution in a first direction, the first direction may be substantially perpendicular to an extending direction of the linear resist test pattern, may be calculated using the LRF. A line spread function (LSF), which may represent an exposure distribution in the first direction, may be calculated using the development rate distribution. The PSF may be estimated using the LSF.

    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.

    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.
