Using the standard oxide recipe (SiO2_res) for 1 min the CSAR looked burned (test 2016-08-19 resist did not look burned after 1 min) and could not be removed by CSAR stripper (AR600-71). Using the following settings the resist did not looked burned and could be removed by CSAR stripper:
Parameter | Recipe name: |
---|---|
Coil Power [W] | 450 |
Platen Power [W] | 80 |
Platen temperature [oC] | 0 |
He flow [sccm] | 174 |
C4F8 flow [sccm] | 5 |
H2 flow [sccm] | 4 |
Pressure [mTorr] | 4 |
Typical results | Negative Resist mask Nanolab result |
---|---|
Etch rate of thermal oxide | ~105 nm/min (<5% etch load) |
Selectivity to CSAR [:1] | ~2 |
Profile [o] | not measured |
Images | none |
Comments | CSAR did not burn and could be removed by AR600-71 |
