摘要： According to an exposure apparatus and an exposure method in the present invention, based on a focus value and a leveling value in each exposure shot calculated based on measurements by a focus sensor, differential absolute value for respective value are calculated. The differential absolute values for the focus values and leveling vaule are compared with predetermined threshold vaule for the respective differential absolute values. When the differential absolute values exceed the threshold value, it is determined that an exposure abnormality exists. In such case, based at least the number of exposure area where the exposure abnormality is occurred and distribution of the exposure area where the exposure abnormality is occurred on the object to be exposed, a kind of the exposure abnormality is identifed. The detection of the exposure abnormality is assured, and a cause of the abnormality is determined without lowering manufacturing capabilities and increasing in cost.
摘要翻译：根据本发明的曝光装置和曝光方法，基于基于由聚焦传感器的测量计算出的每个曝光拍摄中的对焦值和调平值，计算各个值的差分绝对值。对于相应的差分绝对值，将聚焦值和平整度的差分绝对值与预定阈值vaule进行比较。当差分绝对值超过阈值时，确定存在曝光异常。在这种情况下，至少基于曝光异常发生的曝光区域的数量和曝光异物发生的曝光区域的分布，识别曝光异常的种类。确保曝光异常的检测，并且在不降低制造能力和成本增加的情况下确定异常的原因。
