The tungsten evaporation boat must be stored in a dry, inert atmosphere to prevent surface oxidation that can degrade resistive heating performance. Mechanical deformation of the thin 0.3 mm wall or contamination of the V-tub cavity will compromise evaporation uniformity and source loading accuracy.
- Oxidation Sensitivity: Exposure to ambient humidity or oxygen at elevated storage temperatures can form tungsten oxide layers that increase electrical contact resistance and reduce boat lifetime.
- Mechanical Integrity: The 0.3 mm thickness makes the boat susceptible to permanent deformation if handled without support or clamped beyond the specified contact area.
- Contamination Risk: Fingerprint oils or particulate residues inside the V-tub will outgas under vacuum and introduce impurities into the deposited film.
This procedure covers mounting the tungsten evaporation boat into a compatible resistive-heating source holder and performing an initial outgassing cycle. Proper electrical matching and mechanical alignment are required to achieve uniform heating and prevent premature failure.
Required Equipment: Resistive-heating power supply rated for 1.47 V, 204 A, 300 W, Evaporation source holder with straight-type boat clamps, Cleanroom-grade tweezers or vacuum-compatible handling tool
- Inspect the boat
Inspect the boat for visible deformation, cracks, or surface contamination before installation. - Mount the boat
Mount the boat into the source holder clamps, ensuring the V-tub is centered and the 0.3 mm thickness is not over-compressed at the contact points. - Connect the power supply
Connect the power supply leads to the holder terminals and verify the voltage, current, and power settings match the 1.47 V, 204 A, 300 W rating. - Evacuate the chamber
Evacuate the deposition chamber to the required base pressure before applying any heating current. - Outgas the boat
Outgas the boat by ramping current slowly to 80% of the rated 204 A over 5 minutes while monitoring chamber pressure for bursts of adsorbed gas. - Load the evaporation source
Load the evaporation source material into the V-tub, filling no more than 80% of the 1.1 cc capacity to avoid spillage during heating. - Perform the deposition run
Perform the deposition run by increasing current to the process setpoint, ensuring the boat temperature does not exceed the 1200 °C maximum rating.
What are the electrical requirements for this tungsten evaporation boat and how do they affect power supply selection?
The boat requires 1.47 V, 204 A, and 300 W. These values must be matched with the resistive-heating power supply to ensure proper operation and avoid overloading. The product description states these as configuration values for power-supply review.
How do I verify that this straight-type V-tub evaporation boat is compatible with my existing evaporation source holder?
Confirm boat material (tungsten), overall dimensions (0.3 x 15 x 100 mm), tub geometry (V tub), and tub capacity (1.1 cc) against the selected evaporation source holder. The product description emphasizes matching these parameters before installation.
What is the maximum operating temperature of this tungsten evaporation boat and what are the implications for process design?
The maximum temperature rating is 1200 °C. This supports temperature-limit matching with the selected evaporation process. Exceeding this limit could compromise boat integrity, as the source provides this specification for process matching.
This tungsten evaporation boat with straight type V tub geometry (0.3x15x100 mm) is designed for resistive-heating vacuum evaporation, offering a 1.1 cc tub capacity and a 1200°C maximum temperature, requiring careful matching of electrical ratings and mechanical dimensions with the source holder and power supply.
Positive
- Tungsten Construction for Resistive Heating: Tungsten material is selected for its high-temperature stability and compatibility with resistive-heating source configurations, providing reliable performance in vacuum evaporation.
- Precise Dimensional Specifications: Defined overall dimensions (0.3 mm thickness, 15 mm width, 100 mm length) and tub geometry (50 mm length, 5.8 mm depth, 1.1 cc capacity) enable accurate dimensional matching with the evaporation source holder before installation.
Trade-offs
- Requires Source Holder Compatibility Check: The boat material, overall dimensions, tub geometry, and tub capacity must be confirmed against the selected evaporation source holder to ensure proper fit and function.
- Temperature Ceiling at 1200°C: The maximum temperature rating of 1200°C imposes an upper limit for evaporation processes, which may not be sufficient for high-temperature materials requiring higher operating temperatures.
