A photomask and method thereof. In an example method, a photomask may be manufactured by forming an oxide layer on a surface, patterning the oxide layer to form an oxide pattern, the oxide pattern including a plurality of oxide pattern bodies and a plurality of oxide windows, filling the plurality of oxide windows with an absorbent to form an absorbent pattern and reducing the plurality of oxide pattern bodies. An example photomask may include an oxide pattern-based absorbent pattern including a plurality of absorbent pattern bodies and a plurality of absorbent pattern windows.

A reflection device that may include a substrate and a multi-reflection layer formed on the substrate. The multi-reflection layer may be formed of a material capable of reflecting EUV rays. The multi-reflection layer may be formed by stacking a plurality of layer groups, each including a first material layer, a surface-treated layer obtained by surface-treating the first material layer, and a second material layer formed on the surface-treated layer. A method of fabricating the reflection device that may include preparing a substrate and forming a multi-reflection layer on the substrate from a material capable of reflecting EUV rays. The forming of the multi-reflection layer may be performed by repeatedly forming a layer group. The forming of the layer group may include forming a first material layer, surface-treating the first material layer, and forming a second material layer on the surface-treated first material layer.
摘要:
A reflection mask for extreme ultraviolet (EUV) photolithography and a method of fabricating the same, in which the reflection mask includes a substrate, a lower reflection layer formed in a multi-layer structure on the substrate and including a material reflecting EUV light, an upper reflection layer formed in a multi-layer structure on the lower reflection layer and reflecting EUV light, and a phase reversing layer formed between the lower reflection layer and the upper reflection layer in a certain pattern and causing destructive interference between reflection light from the upper reflection layer and reflection light from the lower reflection layer. An incidence of a shadow effect can be reduced and unnecessary EUV light can be eliminated, so that a pattern on the reflection mask can be projected precisely on a silicon wafer. Since the phase reversing layer includes the same material as the reflection layer and an absorption layer, mask fabrication processes can be handled easily.
