Custom OEM Semiconductor Process Materials: SiC, Graphite & Quartz Components

Custom OEM Semiconductor Process Materials: SiC, Graphite & Quartz Components

Semicera is a semiconductor materials and components manufacturer integrating R&D, production, and global sales. With a 40,000 m² factory, over 600 employees, and 100+ R&D engineers, Semicera produces more than 120,000 units annually, serving the LED, IC, third-generation semiconductor, epitaxy, MOCVD, CVD, and photovoltaic industries. This article explains how Semicera's OEM capabilities enable custom SiC coated, graphite, quartz, and carbon-fiber components for critical fab processes such as epitaxy, etch, annealing, and silicon carbide crystal growth.

Problem Definition: Why Standard Process Materials Fall Short

Advanced semiconductor manufacturing demands process materials with extreme purity, thermal stability, and dimensional precision. Off-the-shelf components often lack the necessary coating uniformity, purity level (e.g., total metals below 5 ppm), or geometry required by specific OEM equipment or process recipes. New fab lines, tool upgrades, and R&D prototyping require suppliers that offer true customization—low MOQ, fast lead time, and tailored coating/ material formulations—without sacrificing the certified quality needed for high-yield production.

Industry Background: The Scale of Semiconductor Process Materials

According to SEMI, the global semiconductor materials market reached $67.5 billion in 2024, with wafer fabrication materials accounting for $42.9 billion. Within this market, semiconductor graphite is valued at approximately $1.62 billion (Verified Market Reports), SiC-coated graphite susceptors at $350 million (Valuates Reports), and quartz fabricated parts at $2.21 billion (TECHCET). As process nodes shrink and SiC power devices scale, demand for custom, high-purity hot-zone components—such as MOCVD susceptors, SiC wafer boats, etch rings, and CFC insulation—continues to grow.

Detailed Solution: Semicera's OEM Capabilities for Process Materials

Semicera provides OEM services including customization of voltage and logo. The minimum order quantity is 1 unit, with a typical production lead time of 30–50 days. Monthly capacity exceeds 10,000 units, and quality control involves 100% pre-shipment testing. The product portfolio covers:

• CVD SiC coating graphite carrier (model CVD-01) – Coating thickness 50–150 µm, purity 99.99995% (6N, ≤5 ppm ash), hardness 2500 Vickers (40 GPa), FCC beta-phase polycrystal. Used in MOCVD and RTP.
• CVD TaC coating graphite carrier (model CVD-02) – Coating 25–45 µm, operating temp up to 2200°C, outstanding resistance to NH₃ and H₂ etching. Enables SiC crystal growth and high-temperature epitaxy.
• CVD solid SiC parts (model CVD-03) – 100% bulk solid, density ≥3.21 g/cm³, zero porosity, thermal conductivity ≥150 W/m·K. For SiC crystal growth hot-zone.
