Proposal for Custom Sapphire Products for Semiconductor Manufacturing Equipment [Technical Data Provided]
We will 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 fine products under 1mm as well as large windows around 300mm, as shown in the photo. We excel at closely aligning with our customers' requirements from the design stage, collaboratively creating custom products that are optimal in terms of quality and cost. Inquiries for single units are also welcome, so please feel free to contact us. In addition to basic processing such as cutting, grinding, and polishing, we also support 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, which can 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 (approximately 5μm)) ■ Hard (Vickers hardness: 1750 (A face)) ■ Heat resistant (melting point: 2040℃) ■ Good thermal conductivity (42W/mK at 25℃)

Company information
Our company is a manufacturer of oxide single crystals. In particular, we specialize in the following products: 1. Sapphire (α-Al2O3) 2. SrTiO3 3. Rutile (single crystal of TiO2). Although we are a crystal manufacturer, we also perform a full range of processing, including cutting, grinding, and polishing. Having handled crystals for over 70 years since our founding, we possess extensive knowledge and experience, especially regarding sapphire. Recently, we have also been mass-producing sapphire crystals larger than 300mm, allowing us to accommodate large-shaped products and mass production. We are a small company with about 170 employees, but if there is anything we can assist you with, please feel free to contact us.
