Hello Bernd, Shipley Co. offers standard products for such a Lift-Off process. There is a two coat system, with one developer solution used. The two resist products I use are called LOL2000, and Microposit 1813, but the key is the LOL2000. The pattern is Developed using a third product, LDD-26W. Regards, Neal "Krueger, Bernd (Unaxis Optics BZ)"wrote: Dear All, does anybody has experience in a metal-lift-off-process? I am searching for a resist working fine for soft metal with a thickness of about 300nm. May be you can advise me either negative or positive resists.
