6.1.5.2 Align Kerf Model
The Align Kerf Model is a standard alignment model that can be selected
from the model list. It allows detection of black streets on white
background.
These streets can be used as Main models or Sub-models (the Low model is
always the die model). A model needs to be defined as an Align Kerf Model
during every step of Teach Alignment procedure. The Align Kerf Model can
be found only if the street width falls between the W-min and W-max
values (see
Table A-3). Before teaching alignment, add all the categories
and parameters for each angle in the recipe, save the recipe, and then
teach the alignment.
6.1.6 Model Processing Filters
The model preprocessing mechanism enables detecting the gray levels
variation in the model images during the Teach Alignment process
When the "Model Processing” filter option is defined in the recipe, the
Teach Model and Find Model processes activate the selected option and
perform the defined number of iterations. The results of the preprocessing
are displayed for the user to view.
Each model can be preprocessed by using a different Processing Method.
However, it is possible to assign one Method to all the models, by defining
Figure 6-19: Model Options
Note: Activating this option requires the user to teach/re-teach alignment with
the defined filter.
