    摘要: A method for manufacturing a photomask includes forming a photoresist film on a substrate, and forming a defect detecting pattern on the photoresist film. 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.
