    • A multiple substrate orienter is provided that includes a rotatable substrate handler having a plurality of substrate support portions, each adapted to support a substrate. The multiple substrate orienter also includes a plurality of stacked substrate supports, each adapted to support a substrate. A plurality of substrate orientation marking (SOM) detectors are provided, and each SOM detector is coupled to a different one of the substrate supports and is adapted to identify a presence of an SOM of a substrate positioned close enough to the SOM detector to allow SOM detection by the SOM detector. The multiple substrate orienter further includes a plurality of lift and lower mechanisms, each lift and lower mechanism coupled to a different one of the substrate supports and adapted to individually lift and lower the substrate support to which the lift and lower mechanism is coupled. Alternatively, each lift and lower mechanism may be coupled to a different one of the substrate support portions of the rotatable substrate handler and adapted to individually lift and lower the substrate support portion to which the lift and lower mechanism is coupled. Preferably the multiple substrate orienter includes a controller having program code adapted to simultaneously rough orient a plurality of substrates loaded onto the substrate support portions of the substrate handler, and to individually fine orient each rough oriented substrate. In further aspects of the invention, a substrate orienter capable of orienting one or more substrates is provided, as are methods for orienting substrates as described above.
    • 提供了多个基板取向器,其包括具有多个基板支撑部分的可旋转基板处理器,每个基板支撑部分适于支撑基板。 多个基板取向器还包括多个层叠的基板支撑件,每个基板支撑件适于支撑基板。 提供了多个基板取向标记(SOM)检测器,并且每个SOM检测器耦合到不同的一个基板支撑件,并且适于识别位于距离SOM检测器足够近的基板的SOM的存在以允许SOM 通过SOM检测器检测。 多个基板取向器还包括多个提升和下部机构,每个提升和下部机构联接到不同的一个基板支撑件,并且适于单独升高和降低升降机构和下部机构所联接的基板支撑件。 或者,每个提升和下部机构可以联接到可旋转基板处理器的不同的一个基板支撑部分,并且适于单独升高和降低升降机构和下部机构所联接的基板支撑部分。 优选地,多个基板取向器包括具有程序代码的控制器,该程序代码适用于同时粗略地定向加载到基板处理器的基板支撑部分上的多个基板,并且单独精细地定向每个粗略取向的基板。 在本发明的另一方面,提供了能够定向一个或多个基板的基板定向器,如上所述的用于定向基板的方法。
