Latest calibration runs:

 

Silicon nitride

Recipe: NITRIDE CF4 ETCH (CF4 100 sccm, O2 10 sccm, 75 mTorr, 45 W)

Etch rate: 14,4 nm/min for P5000 nitride (2019-07-08)

 

Silicon oxide

Recipe: OXIDE CHF3 ETCH (CHF3 85 sccm, O2 7 sccm, 50 mTorr, 125 W)

Etch rate: 23,5 nm/min for thermal oxide (2019-07-08)

 

Note: Both of these recipes will etch both oxide and nitride, but they are only calibrated according to the description above. CHF3 will generally produce more polymers.
