Hi, all Not sure the Pt (sputtering) will stick firmly on the substrate or not? as normally Ti/Pt is used for the electrode deposit. But I am going to try Pt directly on Si substrate with PECVD SiO2 (1 or 2 um) due to machine limitation. and if possible, will the Pt electrode firm enought to go through some processes like Piranha, O2 plasma? Thank you very much! Steven
