    • A method for manufacturing an EUVL(Extreme Ultra-Violet Lithography) alternating phase shift mask is provided to decrease reflectivity in a non-phase shift region when EUV light irradiated to a phase shift mask by physically changing a structure of a reflecting layer in the non-phase shift region. A substrate(100) is prepared to have reflecting layers(112,116), multi layering structure, where heterogeneous materials are layered in turn many times. A shielding layer is formed on the reflecting layers on the substrate. The reflecting layers include first and second reflecting layers. An etch stop layer is disposed between the first and second reflecting layers. A photoresist pattern is formed on the shielding layer to expose part thereof. Anisotropic dry etching is performed on the shielding layer by using the first photoresist pattern as an etching mask to form a shielding layer pattern(120a). The first photoresist pattern is removed. As the result, a reflecting region(100a) exposed through the shielding layer pattern and a non-reflecting region(100b) covered by the shielding layer pattern are defined on the first and second reflecting layers on the substrate.

    • PURPOSE: A megasonic cleaning method and device are provided to improve a surface washing effect by creating micro-cavities with high power which is offered from a bubbling creating part and to prevent the generation of faults in a pattern which is formed in a substrate. CONSTITUTION: A cleaning object is loaded(S10). A micro cavity for washing the cleaning object is created(S12). Micro cavities which have stable vibration by the cleaning object are only transferred to a loaded space(S14). Micro cavities which have unstable vibration are destroyed or eliminated when the cleaning object is transferred to the loaded space. Second power for maintaining the vibration of the micro cavity is provided(S16). The surface of the cleaning object is washed using micro cavities of the stable vibration(S18).

    • A method for manufacturing a rim-type photo mask is provided to expose a boundary region with a uniform width by naturally exposing a chrome layer without using a lithography process. A photoresist film(120) is formed on a crystal substrate(100). The photoresist film is applied with a small thickness, such that an edge of a chrome layer(110) is exposed. The thickness of the photoresist film is between 1000 and 5000Š. The photoresist film is a liquid polymer material and developed on the crystal substrate with a low layer covering property. When the thin photoresist film is applied, the edge of the chrome layer is exposed with a constant width. A photoresist pattern is a resultant structure, which is developed, exposed, and applied according to an electron beam lithography process. When a width of the exposed chrome layer is too small, a plasma process or a developing process is performed on the chrome layer, such that a line width of the photoresist film is adjusted.
    • 提供了一种用于制造边缘型光掩模的方法,通过在不使用光刻工艺的情况下自然地暴露铬层,以均匀宽度曝光边界区域。 在晶体基板(100)上形成光致抗蚀剂膜(120)。 以小的厚度施加光致抗蚀剂膜,使得铬层(110)的边缘被暴露。 光致抗蚀剂膜的厚度在1000和5000之间。 光致抗蚀剂膜是液体聚合物材料,并且在具有低层覆盖性的晶体衬底上显影。 当施加薄的光致抗蚀剂膜时,铬层的边缘以恒定的宽度曝光。 光致抗蚀剂图案是根据电子束光刻工艺显影,曝光和施加的结果结构。 当暴露的铬层的宽度太小时,对铬层进行等离子体处理或显影处理,使得调节光致抗蚀剂膜的线宽。
