Chromium evaporation material must be used with a water-cooled copper e-beam hearth and a compatible liner of graphite, Al2O3, BN, or Ta. The evaporation process requires matching the deposition hardware to the material's melting point and film requirements.
- Evaporation Source and Liner Compatibility: Use water-cooled copper e-beam hearth with a compatible liner of graphite, Al2O3, BN, or Ta.
- Preferred Evaporation Method: Use e-beam evaporation as the preferred deposition technique.
- Process Matching Requirement: Match evaporation source hardware and process route to the material's melting point and film requirements.
What is the significance of the Z-ratio of 0.305 for chromium in e-beam evaporation?
The Z-ratio of 0.305 is a material-specific constant used in quartz crystal microbalance (QCM) monitoring to accurately correlate oscillation frequency change with film thickness. For chromium, this value must be set in the deposition controller to achieve precise thickness control during e-beam evaporation. The provided density of 7.2 g/cm³ and Z-ratio are critical parameters for process calibration.
What liner materials are recommended for e-beam evaporation of chromium pieces?
For e-beam evaporation of chromium pieces, compatible liner materials include graphite, Al2O3 (alumina), BN (boron nitride), and tantalum (Ta). The preferred evaporation source is a water-cooled copper e-beam hearth. The 3–6 mm piece size is suitable for loading into these liners.
What is the recommended evaporation method and source configuration for chromium evaporation material?
Chromium evaporation material is preferentially processed by e-beam evaporation using a water-cooled copper e-beam hearth. The material is supplied as 3–6 mm pieces, which are compatible with graphite, Al2O3, BN, or Ta liners. The melting point of 1,857°C and density of 7.2 g/cm³ should be considered when designing the deposition process.
Chromium (Cr) evaporation material with 99.99% purity in 3–6 mm pieces is designed for e-beam deposition. The high melting point (1,857°C) and Z-ratio (0.305) require careful process parameter matching and source power planning.
Positive
- High purity 99.99%: The 99.99% material specification ensures minimal contamination in deposited thin films, critical for reproducible optical, electronic, or barrier layer performance.
- Defined physical form and liner compatibility: Supplied as 3–6 mm pieces, compatible with water-cooled copper e-beam hearth and graphite/Al2O3/BN/Ta liners, facilitating straightforward source loading and process integration.
Trade-offs
- E-beam evaporation preferred: The product is explicitly optimized for e-beam evaporation; thermal evaporation may require higher power or alternative liners to achieve the melting point of 1,857°C, limiting deposition method flexibility.
- Z-ratio calibration required: The Z-ratio of 0.305 must be correctly set in quartz crystal microbalance monitors to achieve accurate thickness control during deposition, requiring operator knowledge of the material-specific parameter.
