Precision thermal hardware directly fabricated in our Donghai facility, supporting LPCVD, ALD, diffusion, and oxidation environments worldwide.
Inside modern chemical vapor deposition (CVD), atomic layer deposition (ALD), and epitaxy reactors, components face sustained thermal cycles, halogen plasma, and stringent trace-metal restrictions.
Fabricated using natural crystal or synthetic silicon precursors yielding SiO₂ ≥ 99.999% (5N). Alkali metals (Li, Na, K) and transition metals (Fe, Cu, Ni) are maintained under strict sub-ppb limits to eliminate crystalline defects and mobile ion diffusion at the wafer boundary.
Featuring an exceptional softening point around 1,683°C and an annealing point of 1,215°C, Southeast Quartz reactor tubes exhibit near-zero creep and sagging during prolonged cycles at 1,150°C. A thermal expansion coefficient of 5.5×10⁻⁷/K virtually nullifies thermal shock degradation.
Hydroxyl ([OH⁻]) content directly governs high-temperature viscosity and devitrification rates. We utilize specialized vacuum electric fusion and post-forming thermal stabilization to tailor OH- concentrations from <5 ppm up to >200 ppm based on process atmosphere chemistry.
Our engineering divisions partner directly with system OEMs and tier-1 fab operators to mitigate chemical failure modes across large scale manufacturing.
In thermal oxidation, polysilicon deposition, and LPCVD silicon nitride furnaces, quartz liners and wafer boats experience corrosive chemistries like SiH₂Cl₂ and NH₃. We deliver precision micro-machined slotted boats, injectors, and double-walled quartz process tubes with precision tight concentricity.
N-type high-efficiency cell manufacturing demands oversized quartz furnace tubes (>450mm OD) capable of continuous operation in boron/phosphorus diffusion chambers. Our customized furnace tubes ensure minimal batch-to-batch runout, lower thermal stress, and maximum wafer throughput.
Engineered for high-pressure, corrosion-sensitive lab synthesis and analytical flow systems. Fused quartz microchannel blocks, source bubblers, and optical reaction cells provide complete chemical inertness against concentrated acids (except HF) alongside superior optical UV-to-NIR transmission.
Located inside the heart of China’s quartz cluster in Donghai County, Southeast Quartz operates automated hot-working torches, 5-axis CNC grinding centers, and certified Class 100 cleanrooms.
Multi-axis computer-controlled hydrogen-oxygen lathes execute flame polishing, flange fusion, and end closures with automated thermal profiling. This eliminates manual stress concentrations and structural wall inconsistencies found in traditional glass blowing shops.
Post-machining quartzware is processed through automated multi-stage HF/nitric acid purification baths to strip micro-fractures and surface contaminations, rinsed in 18MΩ·cm UPW (ultra-pure water), dried under filtered laminar flow, and double vacuum-sealed for zero-particulate delivery.
Every sealed reactor vessel undergoes non-destructive helium mass-spectrometer testing to guarantee ultra-high vacuum (UHV) hermeticity, while coordinate measuring machines (CMM) and laser interferometers verify slot angles, parallelism, and pitch spacing before dispatch.
As semiconductor manufacturing scales past 3nm and wide-bandgap semiconductors (SiC/GaN) accelerate, thermal reactor designs must undergo rapid materials advancement.
Developing plasma chemical vapor deposition (PCVD) synthetic ingots characterized by near-zero bubble content (Class 0 per DIN 58927) and <1 ppb total metallic contamination for sub-2nm gate dielectric atomic deposition cycles.
Integrating trace dopants such as TiO₂ to modify infrared absorption bands, maximizing isothermal heat uniformity across large 300mm wafer batches during ultra-fast spike anneal and epitaxy deposition systems.
Transitioning complex internal manifold channels and customized bubbler nozzles into reality through selective laser sintering (SLS) of nano-silica powders followed by full vitrification, eliminating fragile welding joints.
We lower procurement frictions for international semiconductor manufacturers, Tier-1 EPC contractors, and global research institutions through complete traceability and cross-border logistics guarantees.
Every shipment is accompanied by complete inspection documentation, including GDMS/ICP-MS material purity analysis certificates, optical strain birefringence reports, and helium leak rate audit logs matching your ISO 9001 and IATF 16949 audit requirements.
Custom quartz tubes and assemblies are prone to transport micro-fractures. We utilize finite element modeled internal foam suspension, ISTA-certified shock sensors, and drop-tested moisture barrier wooden crating to ensure safe air and ocean transits worldwide.
Our bilingual quartz engineering desk directly communicates with equipment architects in North America, Europe, and Asia. We review 2D/3D CAD models (STEP, DWG, DXF) to optimize thermal junctions, suggest radius fillets, and eliminate manufacturing cost bottlenecks.
