This application relates to the field of oxide target technology, specifically disclosing an ITZO target and its preparation method. The preparation method of the ITZO target includes the following steps: applying an In-containing... 3+ Sn 4+ Zn 2+ A complexing agent is added to the solution to obtain a mixed solution; the mixed solution is then added dropwise to an ammonia solution and aged to obtain a precursor precipitate; the precursor precipitate is then subjected to spray pyrolysis, cold isostatic pressing, and warm isostatic pressing to obtain an ITZO preform; the ITZO preform is then subjected to programmed temperature calcination and programmed temperature cooling to obtain an ITZO target. This application obtains a uniformly composed and highly dense ITZO target by dynamically controlling the composition of the mixed gas during the programmed temperature cooling process through two static pressing treatments; using this target, a transparent conductive film with high visible light transmittance and excellent electrical properties can be prepared by sputtering, solving the technical problems of uneven composition, low density, and poor quality of sputtered films in existing targets.
