Subject: [mems-talk] selective negative resist stripper

Dear All,

Could anyone tell me how could I remove negative photoresist from a
silicon wafer without affecting metal layer (Ni or AlSi)?

I know that the piranha etching etches the resist in a higher rate than
the metal, but I don't know in which percentage.
