摘要:
A photolithography mask for a semiconductor wafer. The mask includes a protrusion section that protrudes from a handling section of the mask. An outer shape of the handling section enables handling by a mask aligner device. The protrusion includes a face surface provided at a level which is different from a face surface area of the handling section.
