    • In a method of an MRAM device, first and second patterns are formed on a substrate alternately and repeatedly in a second direction. Each first pattern and each second pattern extend in a first direction perpendicular to the second direction. Some of the second patterns are removed to form first openings extending in the first direction. Source lines filling the first openings are formed. A mask is formed on the first and second patterns and the source lines. The mask includes second openings in the first direction, each of which extends in the second direction. Portions of the second patterns exposed by the second openings are removed to form third openings. Third patterns filling the third openings are formed. The second patterns surrounded by the first and third patterns are removed to form fourth openings. Contact plugs filling the fourth openings are formed.
    • 在MRAM器件的方法中,第一和第二图案在第二方向上交替且重复地形成在衬底上。 每个第一图案和每个第二图案沿垂直于第二方向的第一方向延伸。 去除一些第二图案以形成沿第一方向延伸的第一开口。 形成填充第一开口的源极线。 在第一和第二图案和源极线上形成掩模。 掩模包括沿第一方向的第二开口,每个开口沿第二方向延伸。 由第二开口暴露的第二图案的部分被去除以形成第三开口。 形成填充第三开口的第三图案。 由第一图案和第三图案包围的第二图案被去除以形成第四开口。 形成填充第四开口的接触塞。

    • A reconfigurable base station (BS) antenna permits increasing cell capacity by dynamically varying an antenna's configuration according to a wave propagation environment and subscriber distribution. At least two reflective plates each have at least one radiator, a ray dome accommodates the two reflective plates in a hollow interior, and upper and lower caps are combined with upper and lower portions of the ray dome, respectively. Reflective connection members are connected to the respective two reflective plates and the upper and lower caps, so that the two reflective plates are rotatable, and at least one force generator provides a rotation force, and at least one force transfer mechanical portion transfers the rotation force received from the force generator to at least one reflective plate and controls a rotation angle of the at least one reflective plate. At least one of the force generator and the force transfer mechanical portion is combined with the two reflective plates.
    • 可重构基站(BS)天线通过根据波传播环境和用户分配动态地改变天线的配置来允许增加小区容量。 至少两个反射板各自具有至少一个散热器,射线圆顶将两个反射板容纳在中空的内部中,并且上盖和下盖分别与光穹顶的上部和下部组合。 反射连接构件连接到相应的两个反射板和上盖和下盖,使得两个反射板可旋转,并且至少一个力发生器提供旋转力,并且至少一个力传递机械部分将旋转力 从所述力发生器接收到至少一个反射板并且控制所述至少一个反射板的旋转角度。 力发生器和力传递机械部分中的至少一个与两个反射板组合。
