For stock sales of 4-inch 4H-N SiC wafers, contact Orbilink | Manufactured by TanKeBlue, dual-sided CMP, available for immediate delivery.
Orbilink offers 4-inch 4H-N SiC wafers manufactured by TanKeBlue in stock for sale. We can provide dummy grade and ZMP grade (Zero Micropipe Production) for customers who need to procure 4-inch SiC wafers immediately for research and development, equipment evaluation, or prototype considerations. The thickness is 350μm, and the surface finish is double-sided CMP, with consultations available based on application needs. Additionally, Orbilink has established a support system in direct collaboration with the manufacturer as the official distributor of TanKeBlue in Japan. We can accommodate small lot requests, specification confirmations, inventory checks, immediate delivery, issuance of inspection certificates (CoA), price consultations, and custom orders, providing detailed support for both research and development and evaluation purposes. TanKeBlue is recognized as a supplier with a wide range of products in the SiC substrate field. (SiC ingots, SiC as-cut wafers, and SiC epi-wafers are also available.) Please note that due to the end of mass production at the manufacturer, the timing for the next production and arrival is currently undecided, and therefore, the current stock is limited. This product is also suitable for customers considering short lead-time procurement or alternative sources.

Applications/Examples of results
4-inch SiC wafers are often considered in scenarios such as research and development, fundamental evaluations at universities and research institutions, equipment evaluations, prototype considerations, and material confirmations in small lots. Instead of immediately using large diameters with the assumption of mass production, there are cases where 4-inch wafers are chosen as a manageable size to start with process condition verification and fundamental evaluations. On the Orblynk SiC wafer sales page, "equipment evaluation" and "research and development" are explicitly mentioned as applications in the quotation template. In research and evaluation applications, it can be said that 4-inch wafers are more likely to be considered depending on the required quantity and stage of evaluation.
