Patent ID: 8551863

Claim:
A method for manufacturing a ferroelectric device, wherein said ferroelectric device comprising: a lower electrode formed on a side of one surface of a first substrate, a ferroelectric film formed on a opposite side of the lower electrode to a side of the first substrate, and an upper electrode formed on a opposite side of the ferroelectric film to a side of the lower electrode, wherein said ferroelectric film comprises a ferroelectric material, wherein said method comprising: a seed layer forming step of forming a seed layer having a predetermined pattern on a side of one surface of a second substrate and made from a metallic material; a ferroelectric layer forming step of forming a ferroelectric layer made of the ferroelectric material on the side of said one surface of the second substrate after the seed layer farming step; a lower electrode forming step of forming the lower electrode on the ferroelectric layer after the ferroelectric layer forming step; a bonding step of bonding the lower electrode and the first substrate via a bonding layer after the lower electrode forming step; and a transferring step of transferring the ferroelectric film and the seed layer onto the side of said one surface of the first substrate by irradiating a laser beam with a predetermined wavelength from a side of other surface of the second substrate after the bonding step, wherein said ferroelectric film is formed form a first portion of the ferroelectric layer, said first portion overlapping on the seed layer, wherein said laser beam with the predetermined wavelength is a beam with a wavelength, wherein said beam passes though the second substrate, and is reflected by the seed layer, and moreover is absorbed by a second portion of the ferroelectric layer, said second portion not overlapping on the seed layer.
