    摘要: A method of verifying electron beam data used to produce a photomask comprises dividing design data for the photomask into a plurality of repetitive regions, sequentially converting the sequential regions into electron beam data, and determining whether electron beam data corresponding to a current repetitive region is substantially identical to electron beam data corresponding to a previous repetitive region.

    摘要: A method of forming a mask structure for an extreme ultraviolet ray lithography (EUVL) process includes defining a substrate including a first area and a second area, such that the first area has a pattern structure configured to selectively transmit light for the EUVL process and the second area encloses the first area, forming a reflection layer on the substrate, the reflection layer including alternately stacked molybdenum layers and silicon layers on the substrate, forming a capping layer on the reflection layer, forming an absorption pattern on the capping layer, the absorption pattern including a central portion corresponding to the first area of the substrate and a peripheral portion corresponding to the second area of the substrate, and forming a blind layer on the peripheral portion of the absorption pattern.
