Hi Mahnaz,
CDMS group need to test and use the AP 400 due to the serious problems 
encounter during Tungsten wet etching. The photoresist presents 
substantial lifting leaving the wafer almost clean during the etching. 
Implementing  AP400 seems to be our best options since a series of 
tests to improve the photoresist performance have been completed 
without success.

Thank you.
