Hello All I have been trying to make an electrical contact in some molecular conductors using conventional lithography. The conductors are about 5 micron thick and 5 micron 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 samples. Look forward to hear from you. Regards J .. Sharma
