What is a niobium nitride sputtering target?
A niobium nitride (NbN) sputtering target is a compound source for Nb-N thin-film research. The target's nitrogen content and phase should be defined separately from the deposited film's nitrogen balance and functional properties.


Material and Deposition Characteristics
The appropriate sputtering mode depends on target conductivity, thermal behavior, and the power-supply configuration. Many compound ceramic targets are evaluated first with RF magnetron sputtering, especially when electrical resistivity is high. For brittle or low-thermal-conductivity materials, density, backing support, and stable cooling are important for reliable operation.
How to specify niobium nitride sputtering target for an RFQ
The following fields define the order and the tests needed to qualify this target; final availability and acceptance criteria belong in the approved quotation or drawing.
| Decision | Information to provide or verify |
|---|---|
| Material identity | Specify Nb:N composition or phase, impurity limits, and any target-density evidence required for the project. |
| Target and cathode fit | Provide target dimensions, cathode mounting and cooling details, and the intended power or reactive-gas context. |
| Film acceptance | Define film nitrogen content, phase, thickness, and relevant electrical or structural checks under the actual recipe. |
Send the specification and drawing for review. The selected source or target and the deposited film require separate acceptance evidence.

Research applications and film checks
- Ultrathin NbN films are investigated for superconducting nanowire single-photon detectors. Published work often uses reactive sputtering from an Nb metal source; that route is not automatically equivalent to sputtering a pre-compounded NbN target (research example).
- For a detector-film project, define the required film thickness, nitrogen content and phase, superconducting transition and electrical tests under the chosen deposition route.
- Specify the target composition/phase, cathode fit and power/atmosphere context separately from the device acceptance criteria; target identity alone cannot guarantee superconducting performance.
Target Configuration and Ordering Considerations
When requesting a quotation, provide target diameter or rectangular dimensions, thickness, purity or composition, required quantity, and whether a backing plate or bonded assembly is needed. For brittle ceramic or compound targets, it is useful to specify the cathode model, backing-plate material, preferred bonding method, operating power if known, and any density, tolerance, or inspection-document requirements. TFM can review drawings, old-target photos, and application details when custom dimensions are required.
Frequently Asked Questions
What is the main reason to use a Niobium Nitride sputtering target?
It provides a composition-specific source for depositing thin films when the required chemistry is better introduced from a pre-compounded target than from co-sputtering separate elements.
How should the sputtering mode for Niobium Nitride be selected?
The power mode should be selected from target conductivity, thermal behavior, and equipment capability. Many compound ceramic targets are first evaluated with RF magnetron sputtering.
Why are density and microstructure important for Niobium Nitride targets?
Uniform density and microstructure help support stable erosion and thermal behavior, while pores or local defects can increase the risk of cracking, particles, or unstable plasma.
Can a Niobium Nitride target be supplied with a backing plate?
Yes. Where the material is brittle or the cathode requires a backing assembly, bonded configurations can be reviewed according to target size, thickness, cooling, and operating power.
Does target composition always equal film composition?
No. Film chemistry can shift because of different sputtering yields, reactive conditions, substrate temperature, re-sputtering, or chamber history. Verify the film when the chemistry is critical.
What should I provide to request a quotation for Niobium Nitride?
Please provide material composition, purity, dimensions, quantity, target or backing configuration, cathode model or system details, and any drawing, tolerance, or inspection requirements.
