Identity is high even with a defective work.
When the difference between non-defective work and defective
work is a little, the difference in the identity does not appear
apparently.
• Mask the portions other than there is a difference with the mask editor.
• Increase the set value of CMP LACK (Sensitivity of lack for identity).
The brightness irregularity correction for the screen does
not operate properly.
This trouble occurs when BRIGHT COMPENST (Brightness
irregularity correction) was executed when the set value of
SCREEN (Screen size) is different from the present value.
• Execute the brightness irregularity correction again at the set value of
the present SCREEN (Screen size).
There is a brightness irregularity in the image screen.
When the installation condition of the sensor has changed after
the brightness irregularity correction was executed under the other
installation condition, the brightness irregularity correction for the
previous condition may remain in the sensor.
• Execute the brightness irregularity correction again.
Was white paper (not lustrous) used for the brightness irregularity
correction?
• When other paper is used as the reference instead of white paper
without any pattern (not lustrous), correction may not be executed
correctly. Execute the brightness irregularity correction again using
white paper without any pattern (not lustrous).
Edition for masking or the brightness irregularity
correction cannot be executed.
