Hello All
I have been trying to make an electrical contact in some molecular conductors
using conventional lithography. The conductors is about 5 micron thick and 5
micro wide. While doing the liftoff processes the metal is not enough (20nm TI+
100nm AU) to hold the sample while doing liftoff. I tried with more metal, I
couldn't liftoff at all. I have been using AZ5412 image reversal PR to make
undercut profile. I am wondering if any one of you have some experience with
making electrical contacts in relatively thick sample.
Look forward to hear from you.
Regards
