    摘要: Provided are photomasks, methods of fabricating the photomasks, and methods of fabricating a semiconductor device by using the photomasks, in which a critical dimension (CD) of a pattern of a specific region of the photomask is corrected to improve the distribution of CDs of the pattern formed on a wafer. The photomasks may include a substrate and a light-blocking pattern formed on the substrate that includes an absorber layer and an anti-reflection coating (ARC) layer. The light-blocking pattern may include at least one of a first corrected area in which a top surface of the absorber layer is exposed, and a second corrected area in which a correction layer is formed on the ARC layer.

    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: A method of forming a semiconductor device can include determining a shot set including a plurality of shots, based on a final pattern used to form a mask. Shots included in the plurality shots can be classified as being in a first pass shot set or in a second pass shot set, where each can include a plurality of non-directly neighboring shots. A first pass exposure can be performed to radiate a reticle to provide the first pass shot set and a second pass exposure can be performed to radiate the reticle to provide the second pass shot set.
