Technical & Procurement FAQ
Engineering Clarifications for Dutch System Builders
In-depth answers addressing material purity, inspection protocols, cleanroom packaging, and delivery specifics for customers across the Netherlands.
How do BY Photonics fused silica wafers ensure transmission stability under deep-UV (DUV) lithography?
Our synthetic fused silica wafers (JGS1 equivalent to Suprasil / Corning 7980) are manufactured via synthetic chemical vapor deposition (SiCl4 oxidation). This process yields extremely high chemical purity with total trace metal contamination below 1 ppm and controlled hydroxyl (OH) content around 800–1,000 ppm. This molecular structure eliminates color-center formation (solarization) under intensive 193 nm and 248 nm excimer laser radiation, ensuring absolute transmission stability across millions of exposure pulses in photolithography tools.
Can you provide custom notched or flat-ground glass wafers matching SEMI standards for automated Dutch fab handlers?
Yes. We supply 2-inch, 3-inch, 4-inch, 6-inch, 8-inch, and 12-inch wafers fabricated strictly to SEMI standard dimensional tolerances. This includes precision laser-cut orientation flats or SEMI-spec notches with edge profiles rounded via CNC beveling (C-shape or T-shape edges) to prevent edge chipping, particulate shedding, and robotic transfer misalignments inside cleanroom vacuum end-effectors.
What metrology equipment validates the surface quality and total thickness variation (TTV) of your substrates?
Every critical manufacturing batch undergoes non-contact optical metrology. We utilize Zygo VeriFire laser interferometers (632.8 nm) to quantify transmitted wavefront distortion (TWD) and surface flatness down to λ/10. Surface roughness is certified via atomic force microscopy (AFM) and white-light interferometry, confirming root-mean-square roughness (Ra) < 0.2 nm to 0.3 nm. Coordinate Measuring Machines (CMM) and capacitive gauge arrays measure TTV, warp, and bow across wafer diameters.
How are fragile quartz parts and optical flats protected against stress-cracking during international air shipment to the Netherlands?
Optical substrates are ultrasonically cleaned and sealed in single-wafer coin shippers or multi-wafer semiconductor-grade cassettes under cleanroom conditions. Secondary packing employs moisture-proof multi-layer barrier foil bags with desiccant, surrounded by custom high-density closed-cell polyethylene (EPE) shock absorbers within reinforced wooden or composite export cases. Vibration and impact drop indicators are attached to all outbound shipments bound for Schiphol.
What is the standard lead time for bespoke prototype orders compared to recurring batch deliveries?
Custom engineering prototypes (e.g., specific dimensions, non-standard thicknesses from 100 μm to 5 mm, or custom hole patterns) typically require 2 to 3 weeks for tooling setup, machining, lapping, and inspection. For recurring production contracts, we provide buffer inventory arrangements where stocked raw blanks can be finished, clean-packed, and delivered to your Dutch facilities within 5 to 7 business days via air freight.
