摘要:
A method of forming a material (e.g., ferroelectric) film, a method of manufacturing a capacitor, and a method of forming a semiconductor memory device using the method of forming the (e.g., ferroelectric) film are provided. Pursuant to an example embodiment of the present invention, a method of forming a ferroelectric film includes preparing a substrate, depositing an amorphous ferroelectric film on the substrate, and crystallizing the amorphous ferroelectric film by irradiating it with a laser beam. According to still another example embodiment of the present invention, a method of forming a ferroelectric film may reduce the thermal damage to other elements because the ferroelectric film may be formed at a temperature lower than about 500° C. to about 550° C.
