Bubble free in oxide etching

fasheng,
        sounds like a problem we had when etching aluminum.  We used a
commercially available tool that applied a vacuum above the etch area and this
pulled the bubbles out of the etch solution as soon as they formed.  bill

Dear MEMS friends,

I'm trying to eliminate the bubbles in oxide (PSG)
etching by BOE. But I couldn't find any method up
to now. I will really appreciate it if you can
give me some advice.

Thanks.
