Patent number: 9851632Abstract: Disclosed is a phase-shift blankmask, in which a light-shielding film includes a metal compound and having a structure of a multi-layer film or a continuous film, which includes a first light-shielding layer and a second light-shielding layer. The second light-shielding layer has higher optical density at an exposure wavelength per unit thickness (?) than the first light-shielding layer. The first light-shielding layer occupies 70% to 90% of the whole thickness of the light-shielding film. With this, the blankmask secures a light-shielding effect, has an improved etching speed, and makes a resist film thinner, thereby achieving a fine pattern.Type: GrantFiled: July 21, 2015Date of Patent: December 26, 2017Assignee: S&S TECH CO., LTD.Inventors: Kee-Soo Nam, Cheol Shin, Chul-Kyu Yang, Jong-Hwa Lee, Min-Ki Choi, Chang-Jun Kim, Kyu-Jin Jang

Patent number: 9551925Abstract: A blankmask and a photomask using the same are provided. The blankmask can be useful in preventing the loss in thickness of lateral, top and bottom surfaces of a pattern of a light shielding film or a phase shifting film after the manufacture of the photomask by forming protective film, which has an etch selectivity with respect to a pattern of a hard film or the light shielding film, on the light shielding film or the phase shifting film so that the loss of the phase shifting film formed under the light shielding film or the phase shifting film can be prevented when a process of removing the light shielding film disposed under the hard film or a pattern of the light shielding film is performed during a washing process and a process of removing a pattern of the hard film in a method of manufacturing a photomask, thereby securing uniformity in thickness.Type: GrantFiled: January 23, 2015Date of Patent: January 24, 2017Assignee: S&S TECH CO., LTDInventors: Kee-Soo Nam, Chul-Kyu Yang, Geung-Won Kang, Cheol Shin, Jong-Hwa Lee, Min-Ki Choi, Chang-Jun Kim, Kyu-Jin Jang
