Hi all:

I plan to seperately etch 100 nm-thick SiO2 and ~50 nm thick Cr layers.

Does anyone have some experiences of the etching process for Cr and SiO2
layer? If you know, can I share your experience, such as ECR power, RF
power, gas, flow rate, working pressure, and etching rate of each material?

I really appreciate for your time and kind consideration, in advance.
Kind Regards,
Donkoun Lee
