This document outlines the technical constraints for using Cobalt (Co) evaporation material in thin-film deposition processes. All constraints are derived from the material's physical properties and recommended source compatibility.
- Source Compatibility: The evaporation source must be compatible with cobalt's melting point of 1495°C and the specified physical form of 1-3 mm pieces.
- Process Route Selection: The process route (thermal/resistive or e-beam) must be matched to the material's behavior and film requirements prior to execution.
- Deposition Controller Calibration: The density of 8.9 g/cm³ and Z-ratio of 0.343 must be entered into the deposition controller for accurate thickness and rate monitoring.
What evaporation methods are compatible with cobalt (Co) evaporation material (99.95%, 1-3 mm pieces)?
Cobalt (Co) evaporation material is compatible with both thermal/resistive and e-beam evaporation methods. For thermal evaporation, use Mo/W/Ta boats or graphite/alumina crucibles; for e-beam, use an e-beam hearth. The Z-ratio of 0.343 must be entered into the quartz crystal microbalance controller for accurate thickness monitoring.
What source materials are recommended for evaporating cobalt at its melting point of 1495 °C?
Given the melting point of 1495 °C, cobalt evaporation requires source materials that withstand high temperatures. The product supports Mo/W/Ta boats, graphite/alumina crucibles for thermal evaporation, and e-beam hearth for e-beam evaporation. Tungsten or molybdenum boats are commonly used for thermal evaporation of cobalt.
Why is the Z-ratio of 0.343 important for cobalt evaporation in thin-film deposition?
The Z-ratio of 0.343 is a material-specific acoustic impedance factor used in quartz crystal microbalance (QCM) sensors to accurately measure film thickness during deposition. This value must be programmed into the deposition controller to ensure correct thickness readings for cobalt films, as an incorrect Z-ratio leads to systematic thickness errors.
This Cobalt (Co) evaporation material, supplied as 99.95% pure pieces in 1-3 mm size, is designed for thermal and e-beam evaporation with compatibility across multiple boat and crucible materials. Its high purity ensures consistent thin-film deposition, but users must verify source geometry and process parameters to accommodate the 1,495°C melting point.
Positive
- High Purity (99.95%): The 99.95% purity specification supports consistent film stoichiometry and reduces contamination risk in thin-film deposition for research applications.
- Versatile Source Compatibility: Compatible with Mo/W/Ta boats, graphite/alumina crucibles, and e-beam hearths, allowing integration into thermal/resistive or e-beam evaporation systems without additional hardware adaptation.
Trade-offs
- Deposition Source Geometry Check: Buyers must confirm that the pieces' 1-3 mm size range fits their evaporation source geometry and feeder mechanism to avoid loading issues or process interruptions.
- Process Matching to Melting Point: The 1,495°C melting point requires selection of appropriate evaporation source materials and power settings, and the process route must be matched to material behavior for reliable film deposition.
