  • Patent number: 10040220
    Abstract: A hard mask film 2 provided on substrate 1 is formed by tin-containing chromium-containing material. In the chromium-containing material including tin, which forms the hard mask film 2, the etching resistance to fluorine-containing dry etching is equal to or higher than the etching resistance of the tin-free chromium-containing material, and it shows a significantly high etching rate as compared with a chromium-containing material free of tin under conditions for chlorine-containing dry etching. As a result, the time for chlorine-containing dry etching is shortened, and damage to a resist pattern is reduced. Thus, high-precision pattern transfer can be performed. The present invention provides a novel technique for increasing etching process-ability by increasing a dry-etching rate of a hard mask film made of a chromium-containing material while assuring a hard mask function of the hard mask film.

    Abstract: An inorganic material film containing tin within the concentration range of 0.1 atomic percent or higher but no higher than 11.5 atomic percent eliminates the problem in which tin localizes and forms into particles, with the result that these particles turn into defects in an optical film. An inorganic material film for a photomask blank according to the present invention film-formed by sputtering and composed of a chromium-containing material includes a light-shielding layer having electrical conductivity, wherein the light-shielding layer contains 0.1 atomic percent or higher but no higher than 11.5 atomic percent of tin and no higher than 15 atomic percent of oxygen. The lower limit of oxygen concentration is, for example, 3 atomic percent. The inorganic material film has electrical conductivity, which is preferably no higher than 5000 ?/cm2 when evaluated in terms of resistance values.

  • Patent number: 9268212
    Abstract: A light-shielding film 2 is formed on a transparent substrate 1. A hard mask film 3 is formed on this light-shielding film 2. The entire hard mask film 3 is made of a chromium-containing material including tin. The film made a chromium-containing material including tin can cause a significant increase in the etching rate at the time of chlorine-containing dry etching. Furthermore, comparing with a film made of a chromium-containing material in which part of chromium is replaced with a light element, the above film has an equal or higher level of etching resistance to fluorine-dry etching. Thus, burden on a photoresist at the time of etching the chromium-containing material film can be reduced. Therefore, high-precision pattern transfer can be performed even in the case that the resist film is thinned.

  • Patent number: 9188852
    Abstract: A light-shielding film 2 formed on a transparent substrate 1 has a monolayer structure or a multilayer structure. At least one layer is formed by film-formation with a chromium-containing material including tin. The light-shielding film 2 has an optical density of 2 or higher and 4 or lower and has a reflection-preventing function. The layer made of a chromium-containing material including tin, which constitutes the light-shielding film 2, can cause a significant increase in the etching rate at the time of chlorine-containing dry etching including oxygen. Thus, burden on the resist pattern or hard mask pattern at the time of transferring a pattern on the light-shielding film is reduced, and therefore it is possible to carry out pattern transfer with high precision.

  • Patent number: 9158192
    Abstract: A half-tone phase shift film 2 and a light-shielding film 3 are stacked on transparent substrate 1. The light-shielding film 3 has a monolayer structure or a multilayer structure. At least one layer is formed by film-formation with a chromium-containing material including tin. The half-tone phase shift film 2 is made of a molybdenum silicon nitride oxide. The layer made of a chromium-containing material including tin can cause a significant increase in the etching rate at the time of chlorine-containing dry-etching including oxygen. Thus, burden on the resist pattern or hard mask pattern at the time of transferring a pattern on the light-shielding film is reduced, and therefore it is possible to carry out pattern transfer with high precision. The present invention provides a novel technique that can increase a dry-etching rate of a light-shielding film made of a chromium-containing material while assuring various characteristics required for the light-shielding film.
