Abstract:
A microfabrication method, comprising the steps of:(a) providing an SrTiO3 monocrystal substrate having a (100) plane on a surface thereof; (b) forming an SiO2 film on said (100) plane of said SrTiO3 monocrystal substrate; (c) removing a part of said SiO2 film according to a predetermined pattern; (d) providing an H3PO4 solution maintained at a predetermined temperature; (e) immersing said SrTiO3 monocrystal substrate resulting from step (c) in said H3PO4 solution for a predetermined period of time; and (f) taking said SrTiO3 monocrystal substrate out of said H3PO4 solution.
