Hi there, > I am starting work on deposition PZT thin film by sol-gel on > platinized Si substrate. can some body help me in giving some tips on > cleaning of Platinized Silicon substrate or any literature regarding > same. My substrate is Pt(111) on Si(001). Typically the wafers would be cleaned with acetone first and then 2- propanol afterwards. Before you start spin-coating though, you should also anneal the wafers.
