    • A method for manufacturing a lower electrode and a method for a capacitor including the lower electrode are provided to secure a wide surface area of the lower electrode by thermally treating the lower electrode and discharging impurities to form creases on a surface of the lower electrode. A first lower electrode layer(110) is formed on an upper of a semiconductor substrate(100). A second lower electrode layer(120) containing carbon of 20 % to 50 % is formed on an upper of the first lower electrode layer. The carbon contained in the second lower electrode layer is discharged to form a lower electrode having a crease layer(120a) generated thereon.

    • PURPOSE: A bio-rad key of semiconductor device is provided to correct the pattern shift generated in the range which a son scale isn't out of a mother scale, thereby reducing costs and time by reducing re-sampling time of the pattern shift. CONSTITUTION: A bio-rad key of semiconductor device comprises a son scale(20), a mother scale(10) surrounding the son scale, and a large mother(50) scale surrounding the mother scale. When error is generated, correction values of some parameters are automatically calculated by using the son scale(20) and the large mother scale(50) as well as ignoring a signal from the mother scale.
    • 目的:提供半导体器件的生物辐射键,以校正子刻度不超出母尺度的范围内产生的图案偏移,从而通过减少图案偏移的再采样时间来降低成本和时间。 构成:半导体器件的生物雷达键包括儿子秤(20),围绕儿子秤的母秤(10)和围绕母尺度的大型母(50)刻度。 当产生误差时,通过使用子刻度(20)和大母标尺(50)自动计算一些参数的校正值,并忽略来自母尺度的信号。
