This document details the processing requirements and compatibility constraints for the Platinum (Pt) evaporation wire in thermal resistive evaporation systems. The material must be used with compatible source hardware and configured process parameters to achieve reliable thin-film deposition.
- Evaporation Source Compatibility: Platinum wire must be evaporated using W/Mo/Ta filament, basket, coil, or boat sources designed for thermal resistive evaporation.
- Z-Ratio Calibration: The Z-ratio of 0.245 must be entered into the deposition controller for accurate quartz crystal microbalance thickness monitoring.
- Melting Point Requirement: The evaporation source must reach temperatures above the melting point of 1,772°C to vaporize the platinum wire.
What is the Z-ratio of 0.245 for platinum wire and why does it matter for thermal evaporation process control?
The Z-ratio of 0.245 is a material-specific parameter used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance mismatch between the deposited film and the quartz crystal. This value is explicitly listed in the technical specifications for this platinum wire (99.99%, 1.0 mm diameter) and must be entered into the deposition controller to ensure accurate film thickness measurement during thermal evaporation.
Can this 1.0 mm diameter platinum wire be used in a tungsten boat without additional processing?
Yes, the product is supplied as wire with a diameter of 1.0 mm and is explicitly specified for use with W/Mo/Ta filament, basket, coil, or boat in thermal/resistive evaporation systems. The wire form and diameter are selected to facilitate direct loading into these common evaporation sources without requiring additional shaping or processing.
What melting point and density values should be considered when designing a thermal evaporation process for this platinum wire?
The platinum wire has a melting point of 1,772 °C and a density of 21.45 g/cm³ as stated in the technical specifications. These values determine the required power input and source material selection (e.g., tungsten or molybdenum boats must withstand the high melting point) and influence the deposition rate and film properties due to the high density.
Platinum wire evaporation material at 99.99% purity with a defined 1.0 mm diameter is suited for thermal/resistive evaporation using W/Mo/Ta sources. The high melting point (1,772 °C) and high density (21.45 g/cm³) require careful hardware matching and process tuning.
Positive
- High purity 99.99%: The 99.99% purity specification ensures minimal contamination in thin-film deposition, producing consistent film properties for research and development applications.
- Precise wire diameter 1.0 mm: The defined wire diameter of 1.0 mm facilitates reliable loading into standard filament, basket, coil, or boat evaporation sources, simplifying source geometry matching.
Trade-offs
- High melting point requires robust hardware: With a melting point of 1,772 °C, this material demands high-power evaporation sources and refractory metal components, increasing infrastructure requirements for laboratory deployment.
- High density and low Z-ratio affect process control: The density of 21.45 g/cm³ and Z-ratio of 0.245 require careful calibration of deposition rate and film thickness monitoring, adding complexity to process optimization.
