Patent number: 7790339Abstract: A photomask blank has a light-shielding film composed of a single layer of a material containing a transition metal, silicon and nitrogen or a plurality of layers that include at least one layer made of a material containing a transition metal, silicon and nitrogen, and has one or more chrome-based material film. The high transition metal content ensures electrical conductivity, preventing charge-up in the photomask production process, and also provides sufficient chemical stability to cleaning in photomask production. The light-shielding film has a good resistance to dry etching of the chrome-based material film in the presence of chlorine and oxygen, thus ensuring a high processing accuracy.Type: GrantFiled: April 19, 2007Date of Patent: September 7, 2010Assignees: Shin-etsu Chemical Co., Ltd., Toppan Printing Co., Ltd.Inventors: Hiroki Yoshikawa, Yukio Inazuki, Satoshi Okazaki, Takashi Haraguchi, Tadashi Saga, Yuichi Fukushima

Patent number: 7771893Abstract: A light-shielding film for exposure light is formed on one principal plane of a transparent substrate made of quartz or the like that serves as a photomask substrate. The light-shielding film can serve not only as the so-called “light-shielding film” but also as an anti-reflection film. In addition, the light-shielding film has a total thickness of 100 nm or less, 70% or more of which is accounted for by the thickness of a chromium compound that has an optical density (OD) per unit thickness of 0.025 nm?1 for light having a wavelength of 450 nm. In the case where the photomask blank is used for fabricating a mask designed for ArF exposure, the thickness and composition of the light-shielding film are selected in such a manner that the OD of the light-shielding film is 1.2 to 2.3 for 193 or 248 nm wavelength light.Type: GrantFiled: July 20, 2006Date of Patent: August 10, 2010Assignees: Shin-Etsu Chemical Co., Ltd., Toppan Printing Co., Ltd.Inventors: Hiroki Yoshikawa, Hiroshi Kubota, Yoshinori Kinase, Satoshi Okazaki, Tamotsu Maruyama, Takashi Haraguchi, Masahide Iwakata, Yuichi Fukushima, Tadashi Saga
