*The mask's alignment marks for 4inch process:
**For Back Side Alignment (BSA) alignment marks must be located  between -1,0 and +1,0 mm in vertical location from mask center (y=0-+1mm) and  exactly at 45mm in left and right in horizontal location (x=+-45mm).
**For Top Side Alignment (TSA) alignment marks must be located 35-45 mm in left and right in horizontal location and between -2 and +2 mm in vertical location.


*The mask's alignment marks for 6inch process:
*For Top Side Alignment (TSA) alignment marks should be located 35-80 mm in left and right in horizontal location (X) from mask center and between -20 and +20 mm in vertical location (Y)
**Both BSA and TSA must be located between -2,5 and +2,5 mm in vertical location from mask center and 60 mm in left and right in horizontal location.
*For Back Side Alignment (BSA) alignment marks should be located 15-45 mm in left and right in horizontal location (X) from mask center and between -20 and +20 mm in vertical location (Y)
**Please notice that if you plan to use the automatic alignment option the alignment marks must be displaced from y=0 to y=+/- 1,6mm.

If your UV mask is used to define wafers marks in e-beam lithography with JEOL JBX-9500, you should design your alignment marks in a way the JEOL JBX-9500 recognizes. Please follow the guide [Specific%20Process%20Knowledge/Lithography/EBeamLithography/JEOLAlignment for alignment here].
