シチズンファインデバイス List of Products and Services

The sealing bonding technology of Citizen Fine Devices allows for strong adhesion of dissimilar materials by using metal as an adhesive. <Method> ● Strong adhesion is achieved through metal melting via heat treatment. <Result> ● Uniform melting enables sealing without gaps. ● Stable melting allows for strong adhesion. By processing under high temperature and high vacuum, uniform metal melting is realized. Using metal provides high chemical resistance, making it suitable for bonding in medical devices. By utilizing plating, the bonding area can be specified, achieving high bonding precision. We are offering technical materials on sealing bonding! If you are interested, please download the catalog.

Based on the precision processing cultivated in watch production, we can provide solutions that combine MEMS, functional thin film, and packaging technologies. We contribute to a wide range of fields including medical, semiconductor, information and communication, and aerospace. We offer "microplates" that hold samples in suitable shapes at targeted positions using the anchoring effect, and we design "microfluidic" chips for inspection and drug discovery that control liquids through ultra-fine processing, providing consistent support from molding to bonding and inspection. 【Features】 ■ Functional thin films ■ One-stop support from wafer processing to implementation 【Technologies】 ■ Bonding and sealing: We can manufacture consistently from implementation to packaging. Example: Sealing ceramic packages with glass lids using AuSn bonding. ■ Microfabrication: Custom designs tailored to customer needs are possible. Example: Processing of silicon molds, etc. ■ Functional thin films: A wide variety of thin film types are available. Example: Optical thin films, electrode films, water-repellent and hydrophobic films, magnetic films, solder films, etc. *For more details, please refer to the PDF materials or feel free to contact us.
