    • A semiconductor device having a reliable contact is disclosed. The device includes a barrier film deposited on the bottom and side wall of a contact hole opened in a insulating film at a predetermined position; a first metal film filled in the contact hole; and a second metal film of low resistance for forming an interconnection which passes above the contact hole filled in with the first metal film. An oxide film is formed by oxidation on the barrier metal film. And a method of manufacturing the semiconductor device is disclosed. The method includes the steps of: after opening a contact hole at a predetermined position in an insulating film deposited on a semiconductor substrate, forming a barrier film in the bottom and side wall of the contact hole; filling the contact hole with a first metal film while heating the semiconductor substrate at a predetermined temperature; and depositing a second metal film over the surface of the semiconductor device and patterning the second metal film to form an interconnection which passes the contact hole that has been filled in with the first metal film.
    • 公开了具有可靠接触的半导体器件。 该装置包括沉积在预定位置处在绝缘膜上开口的接触孔的底部和侧壁上的阻挡膜; 填充在接触孔中的第一金属膜; 以及用于形成互连件的低电阻的第二金属膜,其通过填充有第一金属膜的接触孔以上。 在阻挡金属膜上通过氧化形成氧化膜。 并且公开了一种制造半导体器件的方法。 该方法包括以下步骤:在沉积在半导体衬底上的绝缘膜中的预定位置打开接触孔之后,在接触孔的底壁和侧壁中形成阻挡膜; 在第一金属膜上填充接触孔,同时在预定温度下加热半导体衬底; 以及在所述半导体器件的表面上沉积第二金属膜,并且对所述第二金属膜进行构图以形成通过已经填充有所述第一金属膜的所述接触孔的互连。

    • A cabin lamp used in, for instance, an airplane having an LED module that is attached to a lamp housing and connected via a connector to a feeder element provided in the lamp housing. The LED module has a printed circuit board and a plurality of reflectors that are installed in a frame-shaped bezel detachably attached to a front end portion of the lamp housing. The printed circuit board is mounted with a plurality of light emitting diodes (LEDs), and the reflectors surround each of the LEDs so as to reflect the light from the LEDs substantially forward.
    • 例如,用于例如具有LED模块的飞机的舱灯,所述LED模块附接到灯壳体并且经由连接器连接到设置在灯壳体中的馈电元件。 LED模块具有印刷电路板和多个反射器,其安装在可拆卸地附接到灯壳体的前端部的框状挡板中。 印刷电路板安装有多个发光二极管(LED),并且反射器围绕每个LED,以便将来自LED的光基本向前反射。
