[labnetwork] Kanto Chemical BOSE IGZO etchant

[Morrison, Richard H., Jr]

Get the SDS of the etchant and see what the etch is made out of.

Then there are on line chemical compatibility charts and see what etches the metals of interest.

Good resource is the CRC Physics and Chemistry handbook and back in the late 1990 there was a paper published by Berkeley that listed etch rates for a tone of semiconductor material, I think the author was Kirt Williams? It was a 2 part article.

Subject: [labnetwork] Kanto Chemical BOSE IGZO etchant

I am new to this email list, let me know if this is appropriate to ask:

Does anyone know if above etchant will attack common metals like Al and Mo?  Where would I look for data or compatibility chart?

Has anyone used it at MTL before?

                              Chong
