摘要： A photomask blank substrate is selected for use in a process where at least a masking film or a phase shift film is deposited on a top surface of a photomask blank substrate to form a photomask blank, the deposited film is patterned to form a photomask, and the photomask is mounted in an exposure tool. The substrate is selected by simulating a change in shape in the top surface of the substrate, from prior to film deposition thereon to when the photomask is mounted in the exposure tool; determining the shape of the substrate top surface prior to the change that will impart to the top surface a flat shape when the photomask is mounted in the exposure tool; and selecting, as an acceptable substrate, a substrate having this top surface shape. The selected substrate has an optimized top surface shape that improves productivity in photomask fabrication.

摘要： An aerial image of a measurement mark (PM) arranged on a measurement mask (Rm) is conformed to a center in an X-axis direction of a slit (122) arranged on a Z tilt stage (38). While illuminating the measurement mark with an illumination light (IL), a slit plate (190) on which the slit (122) is formed is continuously moved in a Z-axis direction, and based on position information of the slit (122) obtained during the movement and a photoelectric conversion signal outputted from an optical sensor (24) that receives the illumination light (IL) from the measurement mark (PM) via a projection optical system (PL) and the slit (122), a best focus position is detected. Thus, the best focus position of the projection optical system can be measured in a short period of time.

摘要： A photomask blank substrate is made by polishing a starting substrate to a specific flatness in a principal surface region on a top surface of the substrate so as to form a polished intermediate product, then additionally polishing the intermediate product. Substrates made in this way exhibit a good surface flatness at the time of wafer exposure. When a photomask fabricated from a blank obtained from such a substrate is held on the mask stage of a wafer exposure system with a vacuum chuck, the substrate surface undergoes minimal warping, enabling exposure patterns of small geometry to be written onto wafers to good position and linewidth accuracies.
