    • Disclosed is an acidic cleaning aqueous solution for aluminum and aluminum alloy and a process for cleaning the same, intended to execute acidic cleaning without using harmful fluoride and chloride ions.The oxidation-reduction potential of a cleaning bath is controlled to be at 0.5 to 0.8 V (vs. Ag-AgCl). The cleaning bath is obtained by diluting an acidic cleaning aqueous solution for aluminum and aluminum alloy to a predetermined volume. The acidic cleaning aqueous solution contains specified amounts of at least one of inorganic acids, Br.sup.- ions and oxidized metal ions, with the addition of a surfactant and oxidizing agent if necessary.It is thus possible to present a uniform etching effect irrespective of low temperature (below 60.degree. C.) without containing fluoride ions and chromic ions within the acidic cleaning aqueous solution. Br.sup.- also has an effect of inhibiting the oxidation-decomposition reaction of the surfactant arising from the oxidizing agent and oxidized metal ions, thereby obtaining a long-life acidic cleaning aqueous solution.
    • 公开了一种用于铝和铝合金的酸性清洗水溶液及其清洗方法,其目的是在不使用有害的氟化物和氯离子的情况下进行酸性清洗。 将清洗液的氧化还原电位控制在0.5〜0.8V(相对于Ag-AgCl)。 通过将铝和铝合金的酸性清洗水溶液稀释至预定体积来获得清洗浴。 酸性清洗水溶液含有规定量的无机酸,Br离子和氧化金属离子中的至少一种,如果需要加入表面活性剂和氧化剂。 因此,在酸性清洗水溶液中不含氟离子和铬离子的情况下,不管低温(低于60℃)都不会出现均匀的蚀刻效果。 Br-还具有抑制由氧化剂和氧化金属离子引起的表面活性剂的氧化分解反应的效果,从而得到长寿命的酸性清洗水溶液。

    • A pretreatment process, carried out prior to a developing process, spouts pure water, namely, a diffusion-assisting liquid for assisting the spread of a developer over the surface of a wafer, through a cleaning liquid spouting nozzle onto a central part of the wafer to form a puddle of pure water. The developer is spouted onto the central part of the wafer for prewetting while the wafer is rotated at a high rotating speed to spread the developer over the surface of the wafer. The developer dissolves the resist film partly and produces a solution. The rotation of the wafer is reversed, for example, within 7 s in which the solution is being produced to reduce the water-repellency of the wafer by spreading the solution over the entire surface of the wafer. Then, the developer is spouted onto the rotating wafer to spread the developer on the surface of the wafer.
    • 在显影过程之前进行的预处理过程,喷出纯水,即用于辅助显影剂在晶片表面上的扩散的扩散辅助液体,通过清洗液喷射喷嘴到达晶片的中心部分 形成一个纯净的水坑。 将显影剂喷射到晶片的中心部分以进行预润湿,同时晶片以高转速旋转以将显影剂铺展在晶片的表面上。 显影剂部分地溶解抗蚀剂膜并产生溶液。 晶片的旋转例如在7秒内相反,其中产生溶液以通过在晶片的整个表面上扩散溶液来降低晶片的拒水性。 然后,将显影剂喷射到旋转的晶片上,以将显影剂铺展在晶片的表面上。

    • A liquid crystal display device includes a liquid crystal display panel and a driving circuit that supplies display signals to a plurality of subpixels of the liquid crystal display panel. The plurality of subpixels are a red subpixel, a green subpixel, a blue subpixel, and a yellow subpixel. When achromatic colors of at least some gray levels among all gray levels are to be displayed by the pixel, display signals which are supplied to a first subpixel group composed of certain two subpixels are display signals of the same grayscale level, whereas display signals which are supplied to a second subpixel group composed of the other two subpixels are display signals of a different grayscale level from the grayscale level of the display signals supplied to the first subpixel group. The first subpixel group includes the yellow subpixel, and the second subpixel group includes the blue subpixel.
