Hi doing. We are making the mask for Deep X-ray lithography. Whenever we try to electroplate the gold on the Si substrate with seed layer Au/Cr. It appears the phenomenon to permeate into the bottom, to plate on bottom and to raise the PR. Could you give me some suggestions on how to solve this problem? Then I really appreciate that.
