Hi all,

I need to fabricate microlens (~400 Micron) and I will use a thick positive
AZP4620 photoresist for that purpose.

1.     I need the spinning curve to deposit AZP4620 in thickness ranging 20-40
Microns,
2.    Is there a difference between AZ4620 to AZP4620 regarding that or is it
essentially the same photoresist ?

Thanks
