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.
■Synthetic quartz photomask substrate
The original plate on which the circuit pattern is formed is called a photomask. A pattern is formed on an optical glass substrate such as quartz using a light-blocking material such as chromium, and the designed pattern is transferred onto the wafer using an exposure device. We provide synthetic quartz photomask substrates with "ground or polished finish."
■Processing example
・Grinding and polishing: Photo masks, quartz substrates, quartz windows, and various types of glass surface polishing processing.
・MC processing: Special shape machining.
・Glass substrate processing: Various sizes, cutting ⇒ Chamfering ⇒ Wrapping ⇒ Polishing ⇒ Cleaning ⇒ Inspection.
・Lens processing: Various spherical/aspherical lenses, flat lenses, and viewing windows.
・Coating processing: AR anti-reflection film, reflective film, etc.
- Fire processing: quartz boards, quartz tanks, quartz tubes, and other special shapes.
