O que muda na passagem de 4 para 6 polegadas
O caso comercial para 6 polegadas é área e compatibilidade de ferramentas: um wafer de 150 mm oferece 2,25 vezes a área de superfície de um wafer de 100 mm e alinha-se melhor com equipamento automatizado de foundry para programas fotónicos 800G e 1.6T. O caso de engenharia é mais complicado. Wafers LNOI maiores amplificam problemas de uniformidade de espessura, bonding, bow, warp e foco litográfico.
On 4-inch wafers, +/-10 nm uniformity may be practical for many programs. On 6-inch wafers, the research note warns that uncorrected variation can rise to 30-50 nm, so buyers should ask whether Gas Cluster Ion Beam trimming is included and whether the supplier guarantees post-trim TTV. The larger bonded area also raises the probability of trapped particles, voids, and gases, so cleanliness and bond inspection data become more important.
Bow and warp are the other practical concern. Lithium niobate and silicon have different coefficients of thermal expansion, so annealing and downstream processing can create stress. At 6 inches, that stress can show up as wafer breakage, focus error, or handling yield loss unless the fab has qualified chucks, recipes, and metrology for 150 mm LNOI.
Checklist de decisão: 6 polegadas vs 4 polegadas
- Choose 6-inch if your foundry flow, stepper, bonding, or DUV process expects 150 mm wafers.
- Choose 6-inch if the program is moving beyond proof-of-concept and needs die count, repeatability, or automated lithography.
- Choose 6-inch only after confirming TTV, bow, warp, particle count, void inspection, and GCIB trimming requirements.
- Stay with 4-inch if wafer cost is the main constraint and the work is still early R&D.
- Stay with 4-inch if your local tools, carriers, wet benches, lithography, or metrology are not qualified for 150 mm LNOI.
- Ask for 6-inch LNOI on quartz if ultra-high bandwidth above 110 GHz is central to the design; verify RF loss data before ordering.
- Model real yield, not only wafer area. The research note cites early 6-inch net functional yields of 60-70% versus mature 4-inch lines above 90% [UNVERIFIED].
Onde os laboratórios compram pequenas quantidades
Small-quantity lab buyers usually care less about theoretical per-die economics and more about a clean purchase path, documented spec, and short lead time. MSE Supplies, SOKA, UniversityWafer, and PMOptics are the practical starting points from the research note, with the caveat that listed prices may describe a specific cut, BOX, film thickness, handle, or promotional stock item.
Before issuing a purchase order, ask the seller to confirm wafer diameter, flat or notch, cut, film thickness tolerance, Espessura BOX, handle material, handle resistivity, MgO doping, TTV, bow, warp, roughness, particle count, wafer map availability, return policy for breakage, and whether the wafer is suitable for the intended process temperature.

Perguntas frequentes
Onde os compradores podem adquirir wafers LNOI de 6 polegadas em 2026?
Start with NanoLN, NGK Insulators, Soitec, Semicorex, Novel Si, or Partow Technologies for direct supplier qualification. For small lab quantities, distributors such as MSE Supplies, SOKA, UniversityWafer, and PMOptics may be easier procurement paths, but all pricing and stock status should be verified before purchase.
Wafers LNOI de 6 polegadas são mais baratos que wafers de 4 polegadas?
Not for most small orders. A 6-inch wafer provides 2.25 times the area of a 4-inch wafer, but trimming, bow control, bonding yield, and early-line defect density can keep the per-wafer price higher until the program uses foundry-scale lithography and volume purchasing.
Que especificação deve um comprador de fotónica integrada solicitar?
A common PIC starting point is X-cut LNOI, 400 nm or 600 nm thin-film lithium niobate, 2-3 um buried oxide, and a high-resistivity silicon or quartz handle. Buyers should also request TTV, bow, warp, roughness, particle count, and whether GCIB trimming is included.
Quando um laboratório deve ficar com wafers LNOI de 4 polegadas?
Stay with 4-inch wafers when the project is still in proof-of-concept, when wafer cost is the main constraint, when the design is tolerant of smaller-area processing, or when local tools are not qualified for 150 mm handling.
