Description

Carbon Evaporation Material is an essential source material used in physical vapor deposition (PVD) processes for producing high-performance thin films. Carbon, typically supplied in the form of high-purity graphite or carbide-based materials, offers excellent thermal stability, chemical inertness, and a sublimation-driven evaporation behavior suitable for a wide range of coating technologies. With a sublimation point above 3,600°C (for graphite) and a density of around 2.0–2.2 g/cc, carbon-based evaporants are stable, reliable, and widely compatible with both resistive and electron-beam evaporation systems.Carbon is one of the most versatile elements in advanced material engineering. Its unique bonding configurations—spanning graphite, amorphous carbon, and carbide forms—enable the deposition of conductive layers, protective coatings, optical films, and carbon-based barrier layers. In industry, carbon thin films are foundational in semiconductor device fabrication, data storage media, optical coatings, DLC (diamond-like carbon) protection layers, and numerous emerging technologies.Carbon and carbon-based materials are evaporated under vacuum conditions to produce films with tailored electrical, mechanical, and tribological properties, making them indispensable across electronics, aerospace, optics, energy storage, and precision manufacturing sectors. From robust protective layers to highly controlled semiconductor interfaces, Carbon Evaporation Materials play a critical role in enabling next-generation thin-film technologies.

Applications of Carbon Evaporation Materials

Carbon (C) and carbon-based evaporation materials—such as graphite, amorphous carbon, carbides (SiC, B₄C, WC, etc.)—play critical roles across advanced technology sectors due to their exceptional thermal, mechanical, electrical, and chemical properties. Below is an overview of their representative applications:


Thin Film Deposition

Carbon is widely used in thin film deposition for semiconductor, storage, and precision coating applications.
Carbon-based thin films—such as amorphous carbon, DLC (diamond-like carbon), and carbide layers—serve as:

  • Protective coatings

  • Hard, wear-resistant surfaces

  • Conductive or resistive layers

  • Barrier layers in semiconductor fabrication

These films are essential in microelectronics, magnetic storage media, and next-generation device architectures.


Optics and Photonics

Carbon and carbide materials are important in optical engineering:

  • Boron carbide (B₄C) and silicon carbide (SiC) are widely used as high-absorbing coatings in EUV, X-ray, and synchrotron optics.

  • Carbon thin films are used as antireflective layers, beam-shaping coatings, and thermal management layers in optical assemblies.

  • Their excellent hardness, stability, and broad-spectrum absorption make them indispensable in high-energy optical systems.


Corrosion & Wear Protection

Carbon-based evaporants—especially DLC and carbide coatings—provide outstanding protection against:

  • Corrosion

  • Abrasion

  • High-temperature oxidation

These coatings are used in cutting tools, dies, bearings, engine components, and harsh-environment mechanical assemblies.


Aerospace and Automotive Industries

Due to its high temperature resistance, low density (for carbides), and strong mechanical properties, carbon-based coatings are applied in:

  • Thermal barrier layers

  • Tribological (low-friction) coatings

  • EMI shielding films

  • Structural protection under extreme heat loads

SiC and B₄C coatings are particularly valuable in aerospace optics, propulsion systems, and high-stress components.


Semiconductors & Electronics

Carbon plays multiple roles in semiconductor device manufacturing:

  • Amorphous carbon is used as a hard mask material in lithography.

  • Carbon films provide conductive/anti-static surfaces in device packaging.

  • Carbides (WC, TiC, SiC) serve as diffusion barriers, gate materials, and high-κ dielectric interfaces.

Carbon evaporation materials are critical in advanced integrated circuits, memory devices, and packaging technologies.
