amtetcher etch rate

[Takane Usui]

Hi AMT users,

I've been using the amtetcher program 3 to etch SiO2, and noticed that
the etch rate seems lower than the listed value 371A/min. Did anyone
notice the same trend? Did anyone calibrate / measure the current etch
rate of program 3? I appreciate your advice!

Thanks,
Takane
