Thin film circuit substrate (submount/carrier) *Technical materials available for free!
Application of film formation technology and thin film processing technology to submounts with increasing demand!
Our company applies and develops the film formation and thin film processing technologies cultivated in the manufacturing of thin film magnetic heads (HDD, FDD) and optical prism components to create thin film electrodes, resistive films, and solder films tailored to substrates such as ceramic substrates, forming them into high-precision fine circuit patterns. We are also capable of patterning on three-dimensional surfaces and thick film Cu plating. Our customers use our products not only in Japan but also in various countries around the world, including Asia and Europe and the Americas. We will continue to develop new technologies in the future. ■ Standard substrate materials (thermal conductivity W/m·K) AlN (170~230) AlN/Cu (~270) SiC (~370) ■ Applications Laser diode (LD) mounting substrates Light-emitting diode (LED) mounting substrates Photodiode (PD) mounting substrates ■ Laser market applications Visible light semiconductor lasers Optical communication (FTTx, data centers, mobile base stations) Consumer industrial applications (sensors, LiDAR, laser processing, medical) Lighting (projectors, automotive headlights), etc.

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.
