    • A lens apparatus for projection includes a plurality of lenses on an optical axis. A shading plate 11 for covering the peripheral portion of the lens to block off light entering the peripheral portion is provided as a single member on the optical axis with the lenses to omit an inking process. In addition, the shading plate 11 is integrally provided with a contrast compensating plate 13 for compensating a projected image, so that it is not required to provide any portions for supporting the contrast compensating plate 13. Moreover, a shading wall 23 for blocking off light leaking out of the peripheral portion of the lens is provided on the peripheral portion of the shading plate 11. Thus, it is possible to provide a lens apparatus for projection, which has a simple structure and which can be easily assembled to reduce the producing costs.
    • 用于投影的透镜装置包括在光轴上的多个透镜。 在透镜上设置用于覆盖透镜的周边部分以阻挡进入周边部分的光的遮光板11作为光轴上的单个部件,以省略墨迹处理。 此外,遮光板11一体地设置有用于补偿投影图像的对比度补偿板13,从而不需要提供用于支撑对比度补偿板13的任何部分。此外,遮光壁23用于遮挡光 在遮光板11的周边部分上设置有从透镜的周边部分漏出的透镜装置。因此,可以提供一种结构简单且易于组装以便降低生产成本的投影透镜装置 。

    • A method of fabricating a semiconductor memory device on a semiconductor substrate is disclosed. A gate electrode that becomes a word line, a bit line, and a charge-storage electrode are formed in a memory cell array region of a semiconductor substrate. A capacitor insulator layer and a plate electrode are formed in that order. Then, a BPSG film is formed in the memory cell array region and in the peripheral circuit region. A resist pattern is formed on the BPSG film, leaving the memory cell array region exposed. Using the resist pattern thus formed as a mask, an etching treatment is applied to remove an upper surface portion of the BPSG film lying within the memory cell array region by a given amount. After the resist pattern is removed, the BPSG film is heated in order that it reflows to planarize.
    • 公开了一种在半导体衬底上制造半导体存储器件的方法。 在半导体衬底的存储单元阵列区域中形成成为字线,位线和电荷存储电极的栅电极。 依次形成电容器绝缘体层和平板电极。 然后,在存储单元阵列区域和外围电路区域中形成BPSG膜。 在BPSG膜上形成抗蚀剂图案,使存储单元阵列区域暴露。 使用如此形成的抗蚀剂图案作为掩模,进行蚀刻处理以将存在于存储单元阵列区域内的BPSG膜的上表面部分除去给定量。 在除去抗蚀剂图案之后,加热BPSG膜,使其回流平坦化。
