Hi Rick, My seed layer is 2400 Å thick. The O2 plasma discus cycle is 1 minute at 50 W. The plating solution is sulfite based. I have one electrical contact which is 3 cm wide x 3 cm long, with 250 um traces to the elements I want to plate. The current density, based on a calculation on the combined areas of the plateable elements is 25 mA/cm^2. I hope this information can help solve the problem! Also if anyone has had problems with plating occurring under structures and pushing the photoresist (also SU-8) off, I’d appreciate hearing how you fixed the issue. Thanks, Sunshine Littlecreek Rutgers University _______________________________________________ Hosted by the MEMS and Nanotechnology Exchange, the country's leading provider of MEMS and Nanotechnology design and fabrication services.
