    摘要: There is provided a method for forming a capacitor of a semiconductor device capable of preventing a dielectric layer from being damaged in forming a tungsten upper electrode on a dielectic layer, and preventing tungsten siliside from being formed on a tungsten film in the following processes. In the present invention, for protecting a dielectric layer, a polisilicon layer is formed on a dielectric layer as a sacrifical reduction layer. Then, a tungsten seed layer is formed on the dielectric layer by reducing WF6 with the polysilicon layer. After that, a tungsten film to be an upper electrode is formed by subsequently carrying out a deposition process using the reaction of WF6 and H2 or SiH4 Then, for preventing tungsten silicide film from being formed in following thermal process, a thermal process is performed in ammonia(NH3) cointaining ambient, or a plasma process using a nitrogen gas or an ammonia gas is performed to nitrize the surface of the tungsten film.

    摘要: Reflective masks, and methods of manufacturing the same, include a reflective multi-layer on a mask substrate, a plurality of support patterns spaced apart from one another in the main trench. The plurality of support patterns are in a main trench of the reflective multi-layer. The plurality of support patterns correspond to areas of the reflective mask not transferred onto an exposure target substrate. The support patterns partition the main trench to form a plurality of auxiliary trenches. The reflective mask further includes a light absorption pattern including a plurality of auxiliary light absorption patterns in the auxiliary trenches.

    摘要: A beam generator for an aerial image generating apparatus includes a laser source for emitting a laser beam and a short wavelength beam source for generating a short wavelength beam by processing the laser beam such that the short wavelength beam is coherent with and has a wavelength shorter than that of the laser beam. A spectral unit includes a quartz plate and a spectral layer coated on a surface of the quartz plate. The spectral layer has a Brewster's angle greater than 70° with respect to the laser beam such that the short wavelength beam is reflected from the spectral unit without the laser beam, increasing the reflectivity of the shortwave beam while decreasing the reflectivity and absorptivity of the laser beam in the spectral unit.
