Support from microfabrication, functional films, bonding and sealing, to packaging.
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.

Company information
The area where Citizen Fine Devices demonstrates its strength is in the realm of functional components that require small size, precision, high accuracy, and high detail. We believe that our mission is to continue providing high-value-added microdevice products by leveraging the unique technologies we have developed over many years. Utilizing metal processing technology rooted in watch manufacturing, we have consistently supplied small, high-precision components to our customers for many years through a fully integrated production line that encompasses process design, machining, assembly, and functional testing, along with the unique development of our own processing machines. Additionally, mass-producing components with high precision and efficiency using brittle materials is also one of our core technologies. By integrating material technology with ultra-precision machining, thin-film technology, and bonding technology, we produce not only high-precision components such as ceramics and quartz but also high-quality functional device products like liquid crystal devices and sensing devices. Continuing to provide high-value-added products to the market is a significant dream for our employees. We will contribute to the creation of new value through manufacturing driven by the challenge spirit of each individual, working towards the realization of that dream.
