Product Description

The power of Semicorex TaC Coated Tube lies in the synergistic combination of the base material and the specialized coating:

High-Purity Isotropic Graphite Foundation: The core of the TaC Coated Tube is formed from ultra-high purity isotropic graphite, renowned for its excellent thermal conductivity, low thermal expansion, and inherent resistance to thermal shock. This foundation provides a robust and stable platform capable of withstanding the rapid temperature fluctuations and high thermal loads characteristic of semiconductor processing.

Tantalum Carbide---A Shield of Durability and Inertness: The CVD-applied TaC coating transforms the graphite substrate, imparting exceptional hardness, wear resistance, and chemical inertness. This protective layer acts as a barrier against the aggressive gases, plasmas, and reactive species encountered during semiconductor fabrication, ensuring the tube’s structural integrity and longevity.

This unique material combination translates into a range of advantages that are critical for advanced semiconductor manufacturing:

Unrivaled Temperature Resistance: TaC boasts one of the highest melting points of all known materials, surpassing even silicon carbide (SiC). This extreme temperature resistance allows the TaC Coated Tube to operate reliably in processes requiring temperatures exceeding 2500°C, enabling the production of next-generation semiconductor devices with demanding thermal budgets.

Ultra-High Purity for Critical Process Control: Maintaining pristine process environments is paramount in semiconductor fabrication. The use of high-purity graphite and the meticulous CVD coating process ensure minimal outgassing or particulate generation from the TaC Coated Tube, preventing contamination that could compromise sensitive wafer surfaces and device performance.

Unwavering Chemical Resistance: The chemical inertness of the TaC Coated Tube provides exceptional resistance to a wide range of corrosive gases, reactive ions, and plasma environments commonly used in semiconductor processes such as etching, deposition, and annealing. This robust chemical stability translates to extended tube lifespan, reduced maintenance requirements, and lower overall cost of ownership.

Enhanced Mechanical Durability for Extended Service Life: The strong bonding force between the TaC coating and the graphite substrate, coupled with the inherent hardness of the TaC Coated Tube, provides exceptional resistance to wear, erosion, and mechanical stress. This enhanced durability translates to longer service life and reduced downtime for replacement, improving process efficiency and throughput.
