Semicera opens 59,000-square-meter semiconductor materials campus in Ningbo

Semicera has launched a new manufacturing campus in Ningbo, China, to bring purification, coating, machining and inspection under one roof for semiconductor process materials. The move is meant to tighten process control for high-purity components used in epitaxy, crystal growth and other high-temperature applications.

Why it matters: - Semicera’s new campus is designed to shorten the path from raw material to qualified semiconductor component. - The integrated setup matters because buyers in this market care about batch-to-batch repeatability, purity and coating consistency more than a single spec sheet number. - The facility gives Semicera more control over process steps that affect particle counts, layer uniformity and part life.

What happened: - Semicera, the brand of Ningbo Miami Advanced Material Technology Co., Ltd., opened a manufacturing campus of about 59,000 square meters in Ningbo, Zhejiang Province. - The site consolidates production of CVD-coated graphite, silicon carbide ceramic, quartz and carbon-composite components for semiconductor process equipment. - The company was founded in 2015. - The campus launched in 2025.

The details: - The site combines raw-material purification, substrate forming, CVD coating deposition, precision machining, cleaning and inspection in one location. - The campus includes high-temperature CVD furnaces, vacuum purification furnaces and horizontal graphitization furnaces. - In-house inspection equipment includes a four-point probe and a coefficient of thermal expansion tester. - Semicera says the on-site setup allows coating thickness, coating adhesion, purity and thermal expansion to be measured internally rather than through subcontractors. - Semicera supplies CVD SiC, TaC and PyC coated parts, recrystallized silicon carbide, high-purity graphite, semiconductor quartz parts and carbon fiber insulation materials. - The company also lists rigid felt, soft felt and other hot-zone materials in its product scope. - Exports account for roughly 40 percent of sales. - Main export markets are the EU, the United States and Asia. - Semicera operates dual research centres and three production bases. - The company says it has more than 50 production lines and about 600 employees. - More than 25 percent of employees work in research and development.

Between the lines: - Semicera is positioning itself as a process-material partner rather than a general materials trader. - The company is leaning on integration and process control as its competitive edge, not just on capacity. - The market backdrop helps that pitch: SEMI reported record global semiconductor materials revenue in 2025, and Stanford’s Emerging Technology Review links part of the demand trend to AI and machine-learning-driven chip innovation. - Public benchmark data for coated graphite, quartz and SiC parts remains limited, so procurement teams often rely on audits, sample testing and long-run production history.

The details: - Semicera publishes specifications across its main coating families. - Its CVD SiC coating graphite carrier, CVD-01, typically has 100 µm coating thickness, with a 50–150 µm range, 99.99995 percent purity, 2500 Vickers hardness and an FCC beta-phase polycrystalline structure with (111) orientation. - The company positions CVD-01 for semiconductor epitaxy and rapid thermal processing applications. - Its CVD TaC coating graphite carrier, CVD-02, typically has 25–45 µm coating thickness and a maximum operating temperature up to 2,200 °C. - CVD-02 is described as resistant to ammonia and hydrogen etching and uses a cubic tantalum carbide matrix. - Semicera positions CVD-TaC parts for compound semiconductor epitaxy, including GaN and SiC processes. - PyC coating is used on high-purity graphite parts to reduce gas permeation and particle shedding during high-temperature heat treatment. - Recrystallized silicon carbide is used for high-temperature components that need purity and thermal shock stability. - SiC wafer boats are rated to 1,600 °C with zero structural deformation and a service life more than five times that of conventional quartz boats. - Semicera says TaC coatings are suited for processes above 2,000 °C, including SiC crystal growth, while SiC coatings are suited for epitaxy and RTP environments below 1,600 °C. - The company publishes SiC furnace tubes up to 3,000 mm in length with wall thickness uniformity of ±0.2 mm. - SiC paddles are listed with deflection of ≤2.0 mm at more than 2,000 mm reach and load capacity up to 15 kg above 1,100 °C. - Quartz wafer boats use GE214 or equivalent fused quartz with SiO2 content of at least 99.99 percent, continuous working temperature of 1,150 °C and short-term capability to 1,300 °C. - Quartz furnace tubes have hydroxyl content below 20 ppm, or below 5 ppm for low-hydroxyl grades. - Supporting materials include isostatic graphite with ash content ≤5 ppm, grain size of 2–5 µm, flexural strength of 45–65 MPa and CTE of 4.0–4.6 × 10^-6 K^-1. - The company also lists CFC material with 2.5D or 3D needle-punched carbon fiber architecture, tensile strength of 90–140 MPa and ash content ≤10 ppm after halogen purification. - Rigid felt is listed with ash content ≤20 ppm, or ≤5 ppm for the ultra grade. - Semicera’s flagship list 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 company says it uses Lean 6-Sigma quality control across production to improve repeatability in coating thickness, porosity and purity. - Semicera reports 100 percent testing before shipment. - Certification records list ISO 9001, ISO 14001 and ISO 45001 certificates valid from December 2025 to December 2026.

What's next: - Semicera says it will continue qualifying parts through customer-specific process conditions rather than fixed catalog items. - The company says it welcomes technical discussion and factory audits. - Commercial terms include OEM customization of voltage and logo, a minimum order quantity of one unit and typical lead times of 30–50 days. - Monthly capacity is listed at more than 10,000 units. - Delivery terms include EXW, FCA, DAP and DDP, with pre-shipment testing as the acceptance criterion. - New customers are quoted 100 percent T/T in advance, while long-term customers pay 70 percent upfront and 30 percent before shipment. - Company-supplied project records describe multi-year supply relationships in North America, Japan, South Korea, Germany and Taiwan. - Those records include 900 units per month for epitaxy in North America, 200 units per month for epitaxy in Japan, 500 pieces per month in South Korea, 10,000 units per year for SiC crystal growth in Germany and 1,000 units per year of CFC insulation in Taiwan. - The company says the next proof point is whether the integrated site translates into qualified positions inside real process tools. - Independent verification of coating and purity data will remain important for customer qualification.

The bottom line: - Semicera is betting that tighter manufacturing integration will become a differentiator in semiconductor process materials, where consistency and contamination control can matter as much as raw capacity.
