Cell Lab 5N (99.999%) Copper (Cu) Pellets Evaporation Materials

Ultra-High Purity Copper for Semiconductor and Thin-Film Deposition

General Description

Cell Lab 5N (99.999%) Copper (Cu) Pellets are high-purity metallic materials designed for precision evaporation in semiconductor, optoelectronic, and sensor applications. With exceptional thermal and electrical conductivity, copper remains one of the most indispensable materials for thin-film metallisation, electrode deposition, and microelectronic fabrication.

Its reddish-orange metallic lustre and high purity ensure consistent film uniformity, minimal contamination, and excellent adhesion across a variety of substrates. Due to its low resistivity and high heat conduction, it is also widely used in vacuum coating, data storage devices, and energy conversion systems.

Key Features

  • Ultra-High Purity (99.999%) – Ensures stable, contamination-free deposition in high-vacuum environments.

  • Outstanding Conductivity – 400 W/m·K thermal conductivity for optimal film performance.

  • Stable and Uniform Evaporation – Excellent film adhesion and reflectivity in vacuum coating systems.

  • Compatible with Multiple Crucibles – Works efficiently with W, Mo, Ta, and Al₂O₃ crucibles.

  • Broad Industrial Relevance – Ideal for semiconductors, MEMS, sensors, and optical coatings.

FAQ

Q1: What makes 5N copper superior for evaporation?
Its 99.999% purity minimises oxide formation and contamination, producing uniform and conductive films for high-end semiconductor or optical use.

Q2: Which crucible materials are most compatible?
Al₂O₃, Molybdenum, and Tantalum crucibles are recommended for consistent temperature control and purity retention.

Q3: Can copper be co-evaporated with other metals?
Yes. It is commonly co-evaporated with nickel, gold, or titanium to create adhesion or barrier layers.

Q4: Is copper suitable for e-beam evaporation?
Yes. It performs excellently under E-beam conditions, yielding high-purity, dense metallic films.
