    • Correction of grinding spindle positions in double-side grinding machines for the simultaneous double-side machining of semiconductor wafers is achieved by torsionally coupling the two grinding spindles, each comprising a grinding disk flange for receiving a grinding disk, and providing a measuring unit with an inclinometer and two sensors for distance measurement, between the two grinding disk flanges such that the grinding spindles are essentially in the position they would have with mounted grinding disks during the grinding process, wherein the coupled grinding spindles are rotated while inclinometer and sensors determine radial and axial correction values of axial alignment to adjust the grinding spindles to a symmetrical orientation. The spindle positions may be corrected under the action of process forces.
    • 通过扭转联接两个研磨主轴来实现用于双面研磨机的双面研磨机中的研磨主轴位置的修正,每个研磨主轴包括用于接收研磨盘的研磨盘凸缘,并且提供具有 倾斜计和两个用于距离测量的传感器,在两个研磨盘凸缘之间,使得研磨主轴基本上处于其在研磨过程中具有安装的研磨盘的位置,其中联接的研磨主轴旋转,而倾斜仪和传感器确定径向和 轴向对准的轴向校正值,以将研磨主轴调整到对称取向。 主轴位置可以在加工力的作用下进行修正。

    • Wire spools used for multiple wire saws for slicing one or more wafers from a workpiece composed of semiconductor material using a wire web including parallel wire sections coated with bonded abrasive grain. The wire spools include a first wire spool configured as a dispensing spool and a second wire spool configured as a receiver spool. A sawing wire coated with bonded abrasive grain runs from the first wire spool via at least one deflection roll to the wire web and from the wire web via at least one deflection roll to the second wire spool. The sawing wire enters into guide grooves of the deflection rolls at an alignment angle α1 and exits the guide grooves of the deflection rolls at an alignment angle α2. The sawing wire has a single layer winding on each of the first and second wire spools.
