High-Performance SiC Roller Rods for a Korean Semiconductor Supplier

June 6, 2025
Latest company case about High-Performance SiC Roller Rods for a Korean Semiconductor Supplier

Client Challenge

A Korean semiconductor materials leader faced critical issues with their high-temperature kilns (1600°C+):

 

  • Dimensional Instability: Traditional alumina roller rods deformed at elevated temperatures, causing substrate misalignment and yield loss.
  • Corrosion Failures: Aggressive byproducts (e.g., HCl, Cl₂) in semiconductor manufacturing eroded alumina rods, requiring replacements every 3 months.
  • Downtime Costs: Frequent maintenance halted production, leading to $120,000 USD/month in losses.

 

Core Pain Points:

 

  • Inability to meet strict thermal stability requirements for precision semiconductor substrates.
  • Short service life of components in corrosive atmospheres.
  • High operational costs from unplanned downtime.

Kegu Solution

Kegu delivered pressureless-sintered silicon carbide (SiC) roller rods tailored to the client’s technical and logistical needs:

Technical Innovations

  1. Custom Engineering
    • Dimensions: 50mm diameter × 1200mm length, optimized for the client’s kiln geometry.
    • Surface Finish: Polished to Ra ≤ 0.8μm to prevent slurry adhesion during substrate coating.
  2. Performance Enhancements
    • Temperature Resistance: Stable up to 1650°C (250°C higher than alumina).
    • Load Capacity: 2500N (15% above theoretical specs), validated via dual-load testing.
    • Corrosion Resistance: Showed <0.01 mm/year erosion in HCl environments (vs. 0.5 mm/year for alumina).
  3. Full Traceability System
    • Raw Materials: 99.5% pure SiC powder sourced from Shaanxi’s premium quartz mines (certified by SGS).
    • Production Data: Real-time records of 2100°C vacuum sintering (12-hour cycle) and furnace parameters.
    • Quality Assurance:
      • Internal: 3-point bend testing (strength ≥600 MPa), XRD phase analysis.
      • External: Certified testing by Korea Testing Laboratory (KTL) for chemical resistance.

Localized Support

  • Korean-Speaking Team: Dedicated technical consultants for seamless communication.
  • Rapid Prototyping: Free sample testing within 7 days to validate compatibility.
  • Short Lead Time: 3-week delivery from order confirmation.

Outcome

  1. Operational Efficiency Gains
    • Downtime Reduced by 80%: From 16 hours/month to 3 hours/month, saving $96,000 USD/month.
    • Service Life Extended 8x: From 3 months to 24+ months, cutting replacement costs by 75%.
  2. Quality & Yield Improvements
    • Substrate Defect Rate Dropped by 65%: Consistent roller rod performance eliminated thermal deformation issues.
    • Compliance with SEMI Standards: Enabled the client to supply major Korean chipmakers (e.g., Samsung Electronics).
  3. Strategic Partnership
    • Order Volume Increased 300%: Within 12 months, driven by reliability and data transparency.
    • Joint R&D Projects: Collaborating on next-gen SiC components for 5G semiconductor fabrication.
