Indium Tin Oxide Sputtering Target

Introduction

Indium tin oxide (ITO) sputtering target are essential materials in the fabrication of thin films for a variety of electronic and optoelectronic applications. ITO is a transparent conductive oxide composed of indium oxide (In₂O₃) and tin oxide (SnO₂), known for its excellent combination of electrical conductivity and optical transparency. This makes ITO an indispensable material in modern technology.
