    摘要: Described herein are methods and systems for aligning a wafer using a wafer leveling map with alignment marks. A set of alignment marks can be selected to create overlay correction parameters to realign the wafer. Alignment marks that are near wafer leveling hotspots, or alignment marks that have poor reproducibility are not selected for realignment purposes. The wafer leveling data is used to determine which alignment marks have poor reproducibility and can create an unstable offset. The wafer leveling data identifies areas on the wafer that are uneven. Only alignment marks which have a stable offset are used to calculate the associated overlay correction parameters.

    摘要: A current flowing through a discharge lamp 4 is detected by a current detecting circuit 5, and the detected current is outputted as a lamp current signal A to a feedback control circuit 7 where a difference between the lamp current signal A and the dimming control signal B is obtained and amplified, and then a simplified signal D is outputted to an adder 12 which adds the amplified signal D to the dimming control signal B to constitute a control signal E. The control signal is fed back to a high frequency power supply 2. When a comparing circuit 15 detects that the light level of the dimming control signal B with respect to the full light becomes higher than or equal to 40% to 60%, the feedback circuit is disconnected by operating a switch 13 provided between an error amplifying circuit 9 and an adder 12 to stop the feedback control.
