    • PURPOSE: A mask blank, a transferring mask, a manufacturing method of the transferring mask, and a manufacturing method of a semiconductor device are provided to reduce various loads of manufacturing processes. CONSTITUTION: A mask blank has a light shielding film for forming a binary mask, to which ArF excimer laser-based exposure light is applied, and forming transferring patterns on a light transmissive substrate. The light shielding film is composed of a stacked structure. The optical density to the exposure light of the light shielding film is 2.8 or more, and the thickness of the light shielding film is 45 nm or less. The lower layer of the stacked structure is composed of a material in which the total content of transition metals and silicon is 90 atomic% or more, and the thickness of the layer is 30 nm or more. The thickness of the upper layer of the stacked structure is within 3-6 nm. Phase difference between exposure light through the light shielding film and exposure light through air as much as the thickness of the light shielding film is 30 degrees or less. A manufacturing method of the transferring mask includes an etching process for etching the light shielding film. A manufacturing method of the semiconductor device forms a circuit pattern on a semiconductor wafer. [Reference numerals] (AA) EMF bias[nm]; (BB) Pitch[nm]
