Proposal for Custom Sapphire Products for Semiconductor Manufacturing Equipment [Technical Data Provided]

We take on any complex sapphire processing requests. Please feel free to contact us even for just one piece.

We are a long-established sapphire manufacturing company with 77 years of history. Since we cultivate large sapphire crystals in-house, we can produce everything from fine products under 1mm to large windows of approximately 300mm, as shown in the photo. We excel at closely aligning with our customers' requirements from the design stage and collaboratively creating custom products that are optimal in terms of quality and cost. Inquiries for even a single piece are welcome, so please feel free to contact us. In addition to basic processing such as cutting, grinding, and polishing, we also accommodate special processing such as drilling, ultrasonic processing, laser processing, tube processing, and coating. Furthermore, please utilize our sapphire products, which have excellent chemical resistance, in semiconductor manufacturing processes that use strong acids and strong alkalis that would cause quartz glass to become opaque. *We are currently offering the results of chemical resistance tests for sapphire products. Technical documentation can be downloaded from the link below. 【Features】 ■ Chemically stable (almost insoluble in acids and alkalis, does not become opaque) ■ Wide transmission characteristics (UV to near-infrared (about 5μm)) ■ Hard (Vickers hardness: 1750 (A face)) ■ Heat resistant (melting point: 2040℃) ■ Good thermal conductivity (42W/mK, 25℃)
