PRODUCT DATA SHEETIndiOx (Indium Oxide) Type T (Target-Grade)®

(Indium Sesquioxide) In2O3Introduction
IndiOx® Type T (In 2 O 3) is a yellow-colored powder witha molecular weight of 277.64. It is a stable ceramic-likematerial which is insoluble in water and volatizes at850°C. IndiOx® Type T is an n-type semiconductor.
The particle morphology of Type T (target-grade) indium
oxide is optimized for powder compaction to produce
high-density ITO and IGZO sputter targets. High-densitytargets result in superior sputter deposited layers onglass and plastic substrates.
To manufacture ITO sputter targets, indium oxide is dopedwith tin oxide (SnO 2) at 10 weight percent (tin oxide doping
can range from 5–10 weight percent). To manufacture
IGZO sputter targets, indium oxide is combined withgallium oxide (Ga2 O 3) and zinc oxide (ZnO).

Properties

ITO-sputtered films function as transparent conductiveoxide (TCO) layers, conducting electricity while alsotransmitting visible light. Although there are several doped
metal oxides that function as TCOs, ITO represents thepremium TCO material since it has the best combination ofelectrical conductivity and optical transparency at a given
thickness. ITO functions as the display electrode material
in both LCDs and OLED displays, and as the touch sensor
in tablets, smartphones, and touch-enabled computers.

IGZO films are increasingly used in the display backplane
to form the channel layer of the thin-film transistors. IGZO
offers higher carrier mobility (compared to a-Si) and lower
process complexity (compared to LTPS), both of which are
crucial for increasing the pixel density on displays.
