Cell Lab 4N (99.99%) Copper Oxide (CuO) Sputtering Target

High-Purity CuO Target for Semiconductor and Photovoltaic Thin Films

General Description

Cell Lab 4N (99.99%) Copper Oxide (CuO) Sputtering Target is designed for precision thin film deposition in semiconductors, solar cells, sensors, and optical coatings. CuO is a p-type semiconductor with excellent optical absorption and electrical properties, making it a preferred material for photovoltaic devices, transparent conductive films, and gas-sensing layers.
Its high chemical stability and purity ensure clean deposition environments and uniform coating performance for research and industrial applications.

Key Features

  • High Purity (99.9–99.99%) – Ensures superior film quality and low impurity concentration.

  • Excellent P-Type Semiconductor Properties – Ideal for thin-film solar and photodetector applications.

  • Stable and Durable Oxide Layer – Provides consistent performance in reactive sputtering.

  • Customisable Form Factors – Discs, plates, and rods available to fit various sputtering systems.

  • Optimised for R&D and Industrial Use – Suitable for laboratory and production-scale deposition.

FAQ

Q1: Is CuO suitable for both DC and RF sputtering systems?
Yes. Copper Oxide targets perform well in both DC and RF systems under controlled oxygen partial pressure.

Q2: Can I request specific dimensions or bonding types?
Yes. Cell Lab supports fully customisable geometries and bonding configurations upon request.

Q3: What is the difference between CuO and Cu₂O targets?
CuO is a p-type semiconductor with a narrower bandgap, ideal for photovoltaic absorption, while Cu₂O offers higher conductivity for transparent conductive layers.

Q4: Does the standard product include a backing plate?
No. A copper backing plate with indium bonding is available as an optional add-on.
