Method for preparing Hf0.5Zr0.5O2 ferroelectric film by ALD for ferroelectric memory applications

The invention discloses a method for preparing a Hf0.5Zr0.5O2 ferroelectric film by ALD for ferroelectric memory applications, characterized by preparing the ferroelectric film by using atomic layer deposition, using a hafnium source and a zirconium source as reaction precursors, using ozone or water as an oxygen source, using a cavity temperature of 250 to 280 degrees centigrade, and using a reaction precursor heating temperature of 75 to 80 degrees centigrade. Compared with a ferroelectric film having a perovskite structure obtained by a conventional process, the ferroelectric film preparedby the method is more liable to be compatible with a standard semiconductor manufacturing process, has higher integration, a lower annealing temperature, a higher annealing rate, shorter annealing time, and a lower ferroelectric layer thickness. The film obtained by a high annealing rate heat treatment process has high remanent polarization, a large dielectric constant, and low leakage current. The preparation method of the invention has high repeatability and can obtain uniform ferroelectric film, and contributes to realizing the wide application prospect of the ferroelectric film in the fields of information storage and integrated circuits.
