    • A semiconductor wafer having an effective chip region set within an effective element region in which an element is formed and required for forming a single chip and an ineffective chip region which includes an ineffective element region in which no element is formed and required for forming a single chip. A degree of unevenness of a surface of the semiconductor wafer is measured at a plurality of sites within a predetermined region by an unevenness measuring section by applying light thereof, so that unevenness data are output. The predetermined region includes either or a part of both of the effective chip region and the ineffective chip region. A reference plane to which light is applied is determined by using only unevenness data of the effective chip region after unevenness data of the ineffective chip region are eliminated from the unevenness data. Inclination of the semiconductor wafer is controlled in accordance with the reference plane obtained through the calculation performed by the calculating section.
    • 将有效芯片区域设置在有效元件区域内的半导体晶片,其中形成元件并形成单个芯片所需的有效芯片区域和无效的芯片区域,其包括无效元件区域,其中没有元件形成并且需要用于形成单个芯片 芯片。 半导体晶片的表面的不均匀度通过不平坦度测量部分在预定区域内的多个位置处被测量,从而输出不均匀性数据。 预定区域包括有效芯片区域和无效芯片区域中的任一个或一部分。 通过在不均匀性数据中消除无效芯片区域的不均匀性数据之后,仅使用有效芯片区域的不均匀性数据来确定施加光的参考平面。 根据通过计算部执行的计算而获得的参考平面来控制半导体晶片的倾斜。
