摘要： A photomask blank is provided comprising an etch stop film which is disposed on a transparent substrate and is resistant to fluorine dry etching and removable by chlorine dry etching, a light-shielding film disposed on the etch stop film and including at least one layer composed of a transition metal/silicon material, and an antireflective film disposed on the light-shielding film. When the light-shielding film is dry etched to form a pattern, pattern size variation arising from pattern density dependency is reduced, so that a photomask is produced at a high accuracy.

摘要： A photomask is manufactured from a photomask blank comprising a transparent substrate and a light-shielding film consisting of upper and lower layers of transition metal-containing silicon base materials, the content of O+N in the upper layer being higher than that of the lower layer.

摘要： Provided is a silicon target material in which particles are not easily generated during a sputtering process and to form a low-defect (high quality) silicon-containing film. A silicon target material having a specific resistance of 20 Ω·cm or more at room temperature is used for forming a silicon-containing film. The silicon target material may be polycrystalline or noncrystalline. However, when the silicon target material is single-crystalline, a more stable discharge state can be obtained. Also, a single-crystal silicon in which crystals are grown by an FZ method is a preferable material as a highly-pure silicon target material because its content of oxygen is low. Further, a target material having n-type conductivity and containing donor impurities is preferable to obtain stable discharge characteristics. Only a single or a plurality of silicon target materials according to the present invention may be used for sputtering film formation of the silicon-containing film.
摘要翻译：提供了一种硅靶材料，其中在溅射工艺期间不容易产生颗粒并形成低缺陷（高质量）含硅膜。使用在室温下电阻率为20Ω·cm·cm以上的硅靶材料形成含硅膜。硅靶材料可以是多晶的或非晶的。然而，当硅靶材料是单晶时，可以获得更稳定的放电状态。此外，由于其含氧量低，因此通过FZ法生长晶体的单晶硅是优选的高纯度硅靶材料。此外，优选具有n型导电性且含有供体杂质的靶材料，以获得稳定的放电特性。根据本发明，只有一种或多种硅靶材料可用于溅射含硅膜的成膜。

摘要： A projection image display device is disclosed in which a trapezoidal distortion and/or aberration are restrained when an image is enlarged and projected obliquely onto a screen. An image generator is connected to an optical system base in such a manner that at least an inclination thereof (on an axis parallel to X axis) with respect to a vertical line and a distance thereof in forward and backward direction (Z axis direction) can be adjusted by an adjusting mechanism. Further, a projecting lens 2 as a first optical system and a free-form curved surface mirror as a second optical system are fixed to the optical system base. The free-form curved surface mirror is rotatable (on an rotary axis parallel to X axis) with respect to the vertical line at a substantial center of the free-form curved surface mirror.
