What is an ITO sputtering target?
An indium tin oxide (ITO) sputtering target is an In2O3/SnO2 conductive-oxide source used to deposit transparent conductive or semiconducting thin films by sputtering. A common purchasing reference is 90:10 wt% In2O3:SnO2; the required ratio, composition basis, purity basis, geometry, and acceptance criteria should be stated in the quotation or approved specification. Film conductivity and optical transmission must be verified on the intended deposition process rather than inferred from the target alone.
Material and Deposition Characteristics
Conductive-oxide sputtering is strongly affected by target density, resistivity, dopant content, power density, working pressure, oxygen content, substrate temperature, and film thickness. RF magnetron sputtering is broadly applicable to ceramic targets, while sufficiently conductive grades may also be compatible with DC or pulsed-DC systems depending on equipment design. The process window should ultimately be tuned against measured film electrical and optical performance.
ITO target selection data
| Selection field | What to specify | Why it matters |
|---|---|---|
| Material identity | Indium tin oxide; state the In2O3:SnO2 ratio | Separates the requested target chemistry from other transparent conductive oxides |
| Composition basis | State whether the ratio is wt%, mol%, or another defined basis | Prevents ambiguity when comparing drawings, quotations, and lot documents |
| Target format | Planar or rotary, with cathode model or drawing when available | Connects the material requirement to the actual source geometry |
| Assembly | Unbonded target or bonded assembly; include backing and interface requirements | Allows geometry and thermal-management requirements to be reviewed together |
| Inspection and documents | List required dimensional, composition, density, electrical, visual, or lot-document checks | Keeps requested evidence distinct from unverified catalog assumptions |
| Film acceptance | Define the electrical, optical, composition, thickness, or other film measurements used by the project | The deposited film depends on the target and the complete process window |

ITO or another transparent conductive oxide?
Use the required film function, deposition system, substrate limits, process-development plan, and acceptance measurements to decide whether ITO or another transparent conductive oxide should be evaluated. The ITO thin-film composition and sputtering guide explains the film/process variables; this product page remains the commercial owner for planar ITO target selection and RFQ intent.
Typical Thin-Film Applications
- Transparent conductive oxide coatings for displays, photovoltaics, smart windows, sensors, and optoelectronics
- Thin-film electronics and transparent electrode development
- Projects balancing optical transmission, conductivity, and process compatibility
Target Configuration and Ordering Considerations
For an ITO target quotation, provide the In2O3:SnO2 ratio and composition basis, requested purity basis, target diameter or rectangular dimensions, thickness, quantity, and planar or rotary format. If an assembly is required, include the cathode model or drawing, backing material, bonding or interface requirement, cooling and operating context if known, and the inspection or lot documents required for acceptance. Send the available target drawing and requirements to TFM for review; unlisted values remain subject to quotation and approved specification.

Frequently Asked Questions
What are Indium Tin Oxide sputtering targets used for?
They are used to deposit transparent conductive or semiconducting oxide films for displays, photovoltaics, smart windows, sensors, and other thin-film electronic or optoelectronic applications.
Can Indium Tin Oxide targets be sputtered with RF or DC power?
RF sputtering is widely applicable to ceramic conductive-oxide targets. Depending on target resistivity and equipment capability, some grades may also be compatible with DC or pulsed-DC operation.
Why is target density important for Indium Tin Oxide?
Higher and more uniform density generally supports more stable erosion and can reduce pores, particles, local hot spots, and arc-related problems. Density should be considered together with microstructure and bonding quality.
How do oxygen partial pressure and power affect Indium Tin Oxide films?
These parameters can influence film composition, carrier concentration, resistivity, transparency, and microstructure. The process window should therefore be optimized against the actual film-performance targets.
Can the dopant level or composition of Indium Tin Oxide be customized?
Yes. The required composition should be stated clearly in the RFQ so that the target formulation and any acceptance criteria can be agreed before production.
What information should I provide to request an Indium Tin Oxide target quotation?
Please provide composition, purity basis, dimensions, quantity, planar or rotary format, backing requirement, cathode model if known, and any density, resistivity, optical, or documentation requirements.
