About This Product
Various optical glasses are used in the semiconductor industry. Also, since optical glass is a hard and brittle material, there are many parts that are similar to crystalline materials in terms of processing. Doujin Sangyo handles a wide variety of optical glasses used in the semiconductor and optical industries. These optical glass products can also be provided with precision processing such as cutting, grinding, polishing, dicing, coating, drilling, MC processing, and fire processing according to the user's requests.
■Optical glass types
Synthetic quartz, fused silica, Tempax, Pyrex, D263, BK7, Eagle XG, chemically strengthened glass, conductive glass (FTO, ITO), etc.
■Quartz substrate
・We provide a variety of high-quality, low-priced glass substrates, from materials to polishing. In particular, we have accumulated a track record of sales of various products, centering on quartz substrates.
・We can provide almost any type of quartz substrate, including thin quartz substrates of 100μm or less, which are difficult to process, and round wafers and square substrates with diameters from φ1mm to φ500mm.
- Regarding glass materials, we can handle synthetic quartz materials, fused quartz materials, and both Japanese and overseas products.
■Characteristics of quartz glass
-Quartz glass has many properties such as high purity, heat resistance, light transmission, chemical resistance, chemical stability, uniformity, and electrical insulation.
- In particular, semiconductor manufacturing equipment requires high-purity quartz glass for processes such as heat treatment film formation, etching, exposure, and wafer cleaning, making it an indispensable material for semiconductor manufacturing processes.
■Basic manufacturing process for quartz substrates
Procurement of quartz materials ⇒ Cutting, grinding, forming, OF and Notch processing, chamfering ⇒ Polishing, cleaning, inspection ⇒ Packing and shipping.
