摘要: It is an object of the present invention to provide a device having a crystalline oxide layer of complex compound which can form a crystalline thin film with high orientation. The lower electrode 13 comprises tantalum layer 11, titanate layer 12 and platinum layer 6, and PZT thin film 8 is formed on the lower electrode 13. Since titanate layer 12 is formed on the lower electrode 13, crystallinity of the PZT thin film can be improved. Therefore, the “lift-off” method can be used with to no thermal treatment needed when forming the platinum layer 6.
