Specific Process Knowledge/Etch/AOE (Advanced Oxide Etch)/Remove resist in the AOE

From LabAdviser


Remove AZ resist in the AOE using the recipe Descum

Parameter Descum
Coil Power [W] 2000
Platen Power [W] 30
Platen temperature [oC] 0
O flow [sccm] 99
Pressure [mTorr] 10.0 (strike pressure 20.0 mTorr)


Typical results tested by bge@danchip
AZ resist etch rate ~41 nm/s

BARC etching

I have tried once etching BARC with recipe m_res_ny:
