  • Patent number: 8609304
    Abstract: An internal defect or the like of a transfer mask is detected using transmitted light quantity distribution data of an inspection apparatus. Using a die-to-die comparison inspection method, inspection light is irradiated to a first region of a thin film to obtain a first transmitted light quantity distribution, the inspection light is also irradiated to a second region of the thin film to obtain a second transmitted light quantity distribution, a predetermined-range difference distribution is produced by plotting coordinates at which difference light quantity values calculated from a comparison between the first transmitted light quantity distribution and the second transmitted light quantity distribution are each not less than a first threshold value and less than a second threshold value, and a selection is made of a transfer mask in which a region with high density of plotting is not detected in the predetermined-range difference distribution.

  • Patent number: 8048594
    Abstract: A photomask blank is for fabricating a phase shift mask having a light-transmissive substrate provided with a phase shift part adapted to give a predetermined phase difference to transmitted exposure light. The phase shift part is a dug-down part formed by digging down the light-transmissive substrate from a surface thereof to a digging depth adapted to produce the predetermined phase difference with respect to exposure light transmitted through the light-transmissive substrate at a portion where the phase shift part is not provided.

  • Patent number: 8012314
    Abstract: There is disclosed a manufacturing method of a phase shift mask blank in which dispersions of phase angle and transmittance among blanks can be reduced as much as possible and yield is satisfactory. In the manufacturing method of the phase shift mask blank, a process of using a sputtering method to continuously form a thin film on a transparent substrate comprises: successively subjecting a plurality of substrates to a series of process of supplying the transparent substrate into a sputtering chamber, forming the thin film for forming a pattern in the sputtering chamber, and discharging the transparent substrate with the film formed thereon from the sputtering chamber; supplying and discharging the transparent substrate substantially at a constant interval; and setting a film formation time to be constant among a plurality of blanks.

  • Patent number: 7632612
    Abstract: A halftone phase shift mask blank for use in manufacturing a halftone phase shift mask comprises a transparent substrate, a light transmitting portion formed on the substrate for transmitting an exposure light beam, a phase shifter portion formed on the substrate for transmitting a part of the exposure light beam as a transmitted light beam and for shifting a phase of the transmitted light beam by a predetermined amount, and a phase shifter film for forming the phase shifter portion. The halftone phase shift mask has an optical characteristic such that light beams passing through the light transmitting portion and through the phase shifter portion cancel each other in the vicinity of a boundary portion therebetween, thereby maintaining and improving an excellent contrast at a boundary portion of an exposure pattern to be transferred onto the surface of an object to be exposed.
