Ion Implantation Tungsten Filament

High-purity ion implantation tungsten filament is a filament used in ion implantation equipment. It is designed to withstand the harsh conditions of the ion implantation process, where ions are accelerated and injected into the target material.

Ion implantation tungsten wire is a key component used in ion implantation machines, mainly in semiconductor manufacturing processes. This type of tungsten wire plays an important role in semiconductor equipment, and its quality and performance directly affect the efficiency of IC process lines. The ion implantation machine is key equipment in the manufacturing process of large-scale integrated circuits, and the role of tungsten wire as an ion source cannot be ignored.

The powder metallurgy process
Co-reduction method powder making:

WO₃+ReO₃ mixed hydrogen reduction (800℃/H₂) to obtain W-Re composite powder (composition deviation <0.5%).

Rotary forging:

Multiple hot rotary forging (1200℃→800℃), diameter from 10mm→0.5mm, grain fiberization (aspect ratio>20:1).

Annealing process:

Step annealing (1400℃/1h→1600℃/0.5h), eliminate residual stress (XRD half peak width reduced by 40%).

Surface treatment technology
Electrolytic polishing:

Mixed acid (NaOH+Na₂CO₃ electrolyte), surface roughness Ra from 1.2μm→0.05μm (AFM detection).

CVD SiC coating:

Depositing a 2μm coating at 1100℃ reduces the plasma erosion rate by 90% (ITER test data).

Ultra-high Purity and Minimal Contamination: The use of ultra-high purity tungsten materials renders the contamination and interference of products and wafers during ion implantation impossible.

Very Fine Grain Structure: The material possesses a smooth grain structure, which enhances the surface's smoothness, improves its mechanical performance, and gives it a fine grain structure.

Very High Melting Point and Heat Resistance: Tungsten possesses an extremely high melting point; therefore, it is stable during ion implantation and at high temperatures, stays stable.

Good Chemical Stability: It resists high temperature reactions and remains chemically stable, which enhances the material's service life.

High Precision Scope: Tungsten implants parts that require high-precision complex techniques or advanced equipment can be worked on using precision tools.

Semiconductor Manufacturing
Ion implantation is a critical process in semiconductor manufacturing. It precisely controls dopant dosage and depth to adjust electrical properties. Tungsten wires serve as a key component of the ion source, ensuring stable electron emission.

Solar Energy Industry
Tungsten is used to produce rotary sputtering targets for solar cell manufacturing.

X-ray and Electron Tubes
In X-ray and electron tubes, tungsten wires generate electron beams, enabling X-ray production or electron transmission.

Surface Treatment and Materials Research
In materials science, ion implantation enhances metal surface properties like hardness and wear resistance. Tungsten wires provide the necessary ion source for this process.

Nanostructure design
Nanocrystalline tungsten wire (<50nm):

Prepared by high-pressure torsion (HPT), tensile strength 2.5GPa (conventional 1.2GPa), but ductility is only 1%.

Hollow tungsten wire:

Inner diameter 50μm, outer diameter 200μm, used for microchannel cooling (heat load bearing capacity increased by 5 times).

Intelligent monitoring
Embedded FBG sensor:

Fiber optics are integrated inside the tungsten wire to monitor strain in real time (accuracy ±5με) and warn of fracture risks.
