Find the P mark at maximum magnification. Click ‘Get P’. Repeat the procedure with the Q mark. Calculate gain and rotation by clicking 'Calculate' and log the results in the Log-window by clicking 'Log result'. Switch off the yellow light after use. Make sure that the rotation is < 0.5 degrees and Gain is close to 1. If this is not the case, you might have entered wrong design coordinates for P and Q or found the wrong marks on the chips or wafer. | ||

In the sdf-file the mark-detection should be set to semi-automatic 'S' (see section 7 in this manual and the separate sdf- and jdf-file preparation manual). In the sdf-file, enter the material center offset out put from PAMS. | ||
