Quartz Wafer Boat (300mm QUARTZ BOAT)

Description

1. Product Overview

The 300mm Quartz Wafer Boat is a precision-engineered carrier engineered for high-temperature semiconductor fabrication processes, including diffusion, oxidation, and annealing. Its primary industrial use lies in safely transporting and supporting 300mm silicon wafers within vertical furnaces, ensuring minimal particle generation and thermal distortion. The key value proposition is exceptional thermal stability and chemical purity, directly enabling higher wafer yields and reduced defect rates. Strategically, this component is critical as fabs transition to larger wafer diameters and more demanding process nodes, where any contamination or warpage translates into millions in lost revenue.

2. Key Specifications & Technical Characteristics

• Chemical composition: Fused quartz (amorphous silicon dioxide, SiO₂)

• Purity level: ≥ 99.995% (high-purity, low metal ion content: < 10 ppb each of Na, K, Fe, Cu)

• Physical characteristics: Translucent/opaque white, rigid slotted structure with precision-machined teeth; density 2.20 g/cm³; max continuous operating temperature 1150°C

• Packaging options: Class 10 cleanroom double-bagged with ESD-safe foam inserts and rigid anti-static shipping box

• Shelf life: Indefinite when stored in clean, dry, non-abrasive environment (no chemical degradation)

3. Core Industrial Applications

• Primary industries: Semiconductor foundries, IDMs (integrated device manufacturers), MEMS producers, advanced LED fabs

• Specific use cases: Vertical furnace batch processing (diffusion, wet/dry oxidation, LPCVD, annealing) for 300mm wafers; high-temperature loading/unloading in automated wafer handling systems

• Performance advantage over alternatives: Outperforms silicon carbide boats in cost-per-run and outperforms standard quartz in thermal shock resistance (lowers crack risk by 40%). Its smooth, non-porous surface reduces particle adhesion by >60% compared to low-grade quartz, directly increasing die yield per batch.

• Efficiency/cost advantage: Precision slot geometry reduces wafer edge contact, minimizing slip dislocations and enabling faster temperature ramps (cycle time reduction of up to 15%).

4. Competitive Advantages

• Quality consistency: Each boat is 3D optical-inspected for slot pitch (±0.05 mm) and parallelism, with lot traceability to raw quartz ingot.

• Supply reliability: Dual-source manufacturing (Japan and Germany-based fused quartz) with buffer stock held in regional hubs (US, EU, SE Asia).

• Logistics capability: Direct drop-ship to fab cleanrooms with real-time shipment tracking and tamper-evident seals.

• Price competitiveness: 12–18% lower total cost of ownership than leading European brands, due to automated forming processes and long-term raw material contracts.

• Sustainability: 100% recyclable quartz scrap buyback program; boat rework service (slot re-machining) extends product life by 2–3 cycles.

• Technical support: Full CAD model availability, on-site installation guidance, and failure analysis reporting within 48 hours.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 units (single lot)

• Bulk 20MT loading capacity: 2,500 units per 20FT container (standard export palletized configuration)
