etch Ti/AuTi on glass substrate

Hi all,

I was wondering if someone could give some suggestions on this experiment?

There are evaporated Ti/Cu/Ti layers (100nm/ 300nm / 100nm) on glass
substrate. AZ9260 photoresist was used to define the structure, but there
is some problem when trying to etch the Ti/CuTi layers. H2O2+NH3.H2O was
tried, but the Ti layer is little etched (at the same time, there are
bubbles and heat generated during the reaction.)

Thanks very much for the help!

Sincerely yours,
Liangliang Zhang
