Sputtered oxide will not work, it is not the same chemically as thermal
oxide.

Subject: [mems-talk] Sputtered oxide as KOH anisotropic wet etching mask

Hello everyone,

I am planning to perform some KOH anisotropic wet etching of silicon to
create V-grooves with ~ 1 um width, and for that I am wondering if I may
use sputtered oxide as the etch mask. I have seen a lot of papers using
thermal oxide but I would like to see if sputtered oxide would work as
well, since I have easy access to a sputtering station. Any advice would
be very much appreciated!

Thank you in advance,
JJ
