How Semicera Builds OEM Semiconductor Process Materials
How Semicera Builds OEM Semiconductor Process Materials
Semicera is a semiconductor materials and components manufacturer headquartered in Ningbo, China, that designs and produces OEM semiconductor process materials for epitaxy, etch, oxidation/diffusion, and silicon carbide crystal growth. Founded in 2015, Semicera operates a 40,000 m² manufacturing base with 600+ employees and an annual output of 120,000 units. This article explains what Semicera's OEM capability includes, which materials and processes are covered, and what buyers should verify when moving from supplier evaluation to order execution.
The Procurement Problem: Process Materials Are Not Off-the-Shelf Commodities
In semiconductor fabrication, process materials are the components that sit inside wafer processing equipment: MOCVD susceptors and trays, etch rings, wafer boats, furnace tubes, paddles, insulation felts, heaters, and crystal-growth crucible structures. These components operate at high temperature, in reactive gas atmospheres, and under plasma conditions. Their purity, coating integrity, and dimensional accuracy affect epitaxial uniformity, particle counts, wafer yield, and equipment uptime.
For buyers at the evaluation-to-execution stage, the decision is not limited to material grade. It also depends on whether a supplier can engineer, machine, coat, inspect, and deliver a component that matches the buyer's process conditions and production schedule. A catalog item with the right product name is not sufficient; the supplier must demonstrate process-specific capability, quality control, and commercial flexibility.
Industry Background: A $67.5 Billion Materials Market
The global semiconductor materials market reached $67.5 billion in revenue in 2024, a 3.8% increase over the previous year, according to SEMI. Wafer fabrication materials, the segment that includes process chemicals and CVD materials, grew 3.3% to $42.9 billion in the same year (SEMI). Several component categories relevant to this article also expanded. The global semiconductor graphite market was valued at approximately $1.62 billion in 2024 and is projected to grow at a CAGR of 7.2% through 2032 (Verified Market Reports). SiC-coated graphite susceptors, which are critical for epitaxial growth, were valued at approximately $350 million in 2024 (Valuates Reports). Quartz fabricated parts used in semiconductor manufacturing reached approximately $2.21 billion in 2024, with 5.5% annual growth (TECHCET).
Two technical trends shape supplier evaluation. First, CVD SiC coating is the dominant protection method for graphite susceptors in MOCVD and epitaxial reactors, due to its high purity and thermal conductivity (Dataintelo). Second, tantalum carbide (TaC) coatings are gaining traction for ultra-high-temperature processes such as SiC crystal growth. Buyers therefore need a supplier that controls the full material chain: substrate, coating, precision machining, and inspection.

Product Portfolio and Material Families
Semicera's main products are CVD SiC coating parts, CVD TaC coating parts, CVD PyC coating parts, SiC ceramic parts, semiconductor advanced ceramic parts, quartz parts, carbon fiber parts, and CFC material. These products serve LED, IC integrated circuits, third-generation semiconductors, epitaxy, MOCVD, CVD, and photovoltaic applications.
The product family includes SiC-coated graphite susceptors, TaC-coated diversion rings, SiC wafer boats, semiconductor quartz parts, and high-purity graphite components with impurity levels below 5 ppm. The hot-zone range also includes wafer boats, susceptors, preheat rings, furnace tubes, furnace thermal field materials, rigid felt, soft felt, and CFC components such as heaters, bolts, and crucibles.
Process Coverage
Semicera's OEM process materials map to specific process steps as follows:
Epitaxy / MOCVD / RTP: CVD SiC-coated graphite carriers (model CVD-01) and CVD TaC-coated graphite carriers (model CVD-02), used as MOCVD multi-pocket wafer susceptors and trays.

General process support: semiconductor graphite, supplied as ultra-fine-grain isostatic graphite blocks and machined parts.
Coating and Purity Parameters
Coating quality is central to Semicera's epitaxy and high-temperature components. The CVD SiC coating is specified with a typical thickness of 100 µm (range 50–150 µm), a purity level of 99.99995% (6N grade, total ash ≤5 ppm), and a coating hardness of 2500 Vickers (40 GPa); the crystal structure is FCC beta-phase polycrystal with (111) orientation. The CVD TaC coating uses a cubic tantalum carbide matrix with a typical thickness of 25–45 µm, operates up to 2200°C, and has outstanding resistance to ammonia (NH3) and hydrogen (H2) etching.
For structural applications, CVD solid SiC parts reach a density of ≥3.21 g/cm³ with 0% porosity and thermal conductivity ≥150 W/m·K. Etch rings hold total metal purity below 5 ppb and a flatness tolerance of 10 µm or better.

Step by Step: How an OEM Process Material Program Runs
Semicera's OEM process material program follows a specification-to-shipment sequence. The buyer and the Semicera engineering team align on the following points before production begins.
- Define the process and component function. Identify the target process (epitaxy, etch, oxidation/diffusion, or crystal growth) and the component type: susceptor, wafer boat, furnace tube, etch ring, paddle, felt, or CFC structure.
- Set the material and purity grade. Select the substrate family: isostatic graphite, CVD SiC, SiSiC/RSiC, quartz, or carbon-fiber composite. Confirm the required purity, such as graphite ash ≤5 ppm, CVD SiC 99.99995%, or quartz SiO2 ≥99.99%.
- Confirm the coating specification. Choose CVD SiC (50–150 µm), CVD TaC (25–45 µm, up to 2200°C), PyC coating, or an uncoated material based on operating temperature and gas chemistry.
- Verify dimensional and mechanical limits. Check tolerances such as quartz boat slot pitch ±0.05 mm, SiC furnace tube wall thickness ±0.2 mm, SiC paddle deflection ≤2.0 mm at maximum reach, and etch ring flatness ≤10 µm.
- Review quality control. Semicera performs 100% testing during production and pre-shipment testing before delivery, under ISO 9001, ISO 14001, and ISO 45001 systems.
- Align commercial terms. MOQ is 1 unit; monthly OEM capacity exceeds 10,000 units; typical production lead time is 30–50 days; delivery can be quoted as EXW, FCA, DAP, or DDP.
- Plan support and repeat supply. After-sales remote support is available, and long-term cooperation customers are offered extended payment terms of 70% T/T in advance and 30% before shipment.

One limitation worth noting: OEM material performance depends on the accuracy of the buyer's specification. Process temperature, gas chemistry, and component dimensions determine material and coating selection, and Semicera's pre-shipment test is the formal acceptance gate before delivery. Buyers should finalize the drawing and parameter sheet before production begins.
