Abstract: Disclosed are photomasks, methods of fabricating the same, and methods of manufacturing semiconductor devices using the same. The photomask comprises a substrate including a pattern region and a peripheral region around the pattern region, a reflection layer on the pattern region and extending onto the peripheral region, an absorption structure on the reflection layer, and a dielectric pattern on the absorption structure on the peripheral region and exposing the absorption structure on the pattern region.
