제목 Investigation of surface rearrangement of siloxane modified polyimide using NEXAFS
초록 Polydimethylsiloxane modified polyimide has very good adhesion properties to SiO2, metals such as Al, Ni-Fe Alloy and etc. But it has some weak point of dewetting of photoresist for lithography because of too low surface energy due to siloxane migaration to surface. SDA of poly(dimethylsiloxane-co-diphenylsiloxane) modified polyimide could be wetted with photoresist. This was cause by rearrangement of siloxane. polydimethylsiloxane was arranged on surface in non polar atmosphere-air but polydiphenylsiloxane was rearranged on surface in polar atmosphere-photoresist. We investigated the polar-non polar surface rearrangement of poly(imide-siloxane) using x-ray photoelectron spectroscopy (XPS) and near edge x-ray absorption fine structure (NEXAFS) spectroscopy. Also dynamic contact angle data explained this phenomena. The initial advancing angles of polydimethylsiloxane modified polyimide and poly(dimethylsiloxane-co-diphenylsiloxane) modified polyimide were almost same but equilibrium advancing angle and receding angle of poly(dimethylsiloxane-co-diphenylsiloxane) modified polyimide were smaller than that of polydimethylsiloxane modified polyimide.
