Mark Level
Set the threshold levels of the ducial marks. In normal cases, set "High".
High
: Both identity and similarity between the shape of a ducial mark
and the real image are detected on a high level.
Middle
: Either identity or similarity between the shape of a ducial mark
and the real image are detected on a middle level.
Low
: Both identity and similarity between the shape of a ducial mark
and the real image are detected on a low level.
Note
(a)
Identity
: Degree of identity between the shapes of the specied
mark and the real image (including the size)
(b)
Similarity
: Degree of similarity between the shapes of the specied
mark and the real image
