Engineered from Grade-A synthetic fused silica (JGS1) and natural flame-fused quartz (JGS2/JGS3), ensuring flawless thermal stability, electrical insulation, and extreme UV-IR transmissive metrics.
Serving critical industrial facilities across Taguspark (Oeiras), Madan Parque (Caparica), and academic cleanrooms at Instituto Superior Técnico with SEMI-compliant quartz components.
Research units along the Tagus corridor utilize our double-side polished (DSP) synthetic quartz wafer discs (100mm, 150mm, and 200mm) as biocompatible, dielectric substrates for microfluidic chips, lab-on-a-chip diagnostic cells, and acoustic wave resonators requiring low auto-fluorescence.
For advanced solar cell research and thin-film passivation lines in Setúbal and Sintra, our high-purity (≥99.99% SiO₂) diffusion furnace tubes and slot-welded quartz boats resist devitrification under prolonged operation up to 1150°C, preventing metallic trace cross-contamination.
Integrated photonics groups developing photonic integrated circuits (PICs) rely on our JGS1 grade fused silica windows. With superior optical transmission from 185 nm to 2500 nm, these substrates deliver non-distorting wave-front performance for UV photolithography masks and beam combiners.
Under the European Chips Act and national digitization initiatives, Portugal's high-tech manufacturing landscape is experiencing rapid modernization, imposing tighter requirements on raw material purity and delivery pipelines.
Nanofabrication institutes are shifting from standard mechanical lap-polishing to advanced Chemical Mechanical Planarization (CMP). Our Lisbon clients demand surface roughness Ra ≤ 0.5 nm with Total Thickness Variation (TTV) below 5 µm to eliminate focal offsets during e-beam lithography.
With Portugal expanding wide-bandgap (SiC and GaN) epitaxy research, thermal performance is non-negotiable. Our pure quartz carriers offer a coefficient of thermal expansion (CTE) of 5.5 × 10⁻⁷ /°C, drastically minimizing wafer warping and mechanical shock during high-temperature thermal cycling.
Portuguese procurement managers face severe European stockouts. Direct collaboration with our SGS onsite-verified manufacturing facilities eliminates tier-2 trading markups, guarantees batch-to-batch traceability, and provides rapid air cargo transit directly into Lisbon Humberto Delgado Airport (LIS).

Uncompromising industrial rigor backed by independent third-party audits and direct source integration.
Our 14,271 m² production infrastructure in Lianyungang operates under complete onsite verification by SGS Group. We handle the entire chain in-house: raw quartz crushing, chemical acid pickling, furnace pulling, and automated CNC five-axis milling.
Devitrification and micro-cracking occur under internal mechanical stress. Every single boat, tube, and custom-lapped wafer is cycled through automated annealing furnaces (up to 1215°C) and individually checked via polarization stress testers prior to shipping.
From single-piece laboratory prototypes to multi-thousand production series, our technical sales engineers parse STEP, DWG, and PDF technical drawings, advising on optimal dimensional tolerances (±0.02 mm), edge chamfering, and flat-ground orientations.
Fragile, ultra-thin quartz sheets (0.1 mm) and precision wafer boats are packaged in dust-free Class 10,000 cleanroom environments, utilizing custom vacuum blister packing, shock-absorbing high-density polyethylene foams, and reinforced export-grade wooden cases.
Key details regarding regulatory compliance, lead times, custom manufacturing, and international logistics.
We routinely supply engineering teams and industrial facilities throughout Portugal under standard Incoterms (DAP, DDP, CIF, or FOB). Orders shipped via express air freight typically clear customs at Lisbon Humberto Delgado Airport (LIS) within 4 to 7 business days. All shipments include complete commercial invoices, certificates of conformity (CoC), and detailed packing lists to ensure seamless clearance with the Portuguese Tax and Customs Authority (Autoridade Tributária e Aduaneira).
Every delivery can be accompanied by an official RoHS Compliance Certificate, verifying that hazardous substances (lead, cadmium, mercury, hexavalent chromium, PBB, PBDE) remain well below EU legal thresholds. In addition, for semiconductor-grade wafers, we supply detailed ICP-MS (Inductively Coupled Plasma Mass Spectrometry) impurity reports tracking trace elements (Fe, Cu, Ni, Na, K, Li, Al) down to parts-per-billion (ppb) levels.
Yes. We support university laboratories, R&D centers, and advanced technology startups across Greater Lisbon with low Minimum Order Quantities (MOQs) starting from 1 to 5 pieces on standard and custom-machined items. This enables full design verification, thermal testing, and lithography trial runs prior to committing to production-scale batches.
Our five-axis CNC machining, precision surface grinders, and ultrasonic drilling centers routinely achieve linear dimensional tolerances of ±0.05 mm, and down to ±0.02 mm upon request. For optical surfaces and wafer substrates, we provide surface parallelism < 10 arcseconds, flatness down to λ/4 @ 632.8 nm, and scratch-dig specifications reaching 20/10.
Our multi-tier export packaging has been tested and refined across thousands of fragile deliveries worldwide. Wafers are packed in semiconductor-grade cassette boxes or individual coin trays. Complex, welded quartz apparatus—such as wafer boats or triple-bore flow tubes—are suspended inside multi-layer polyurethane foam shock blocks and housed within custom-reinforced wooden cases. We maintain a zero-breakage guarantee on properly handled air-cargo shipments.
Whether you require standard JGS1 wafers, customized thermal diffusion boats, or complex CNC-milled fused silica glass assemblies, our engineering staff is available to provide technical feasibility analyses and comprehensive quotations.
