Thin-film Technology

Custom-made thin-films at customer's requests

From optical thin film products to metal thin film on substrate, we can formulate thin-films on substrates such as glass, crystal, aluminum nitride and plastic by using various membrane technologies to match each customer's request. There are also various thin-film types including electrode film, conductor film, solder film, optical filter, and high reflecting coating to meet a wide range of needs. For example, in case of solder film, we customize a product with particular characteristics to melt in a way customer wants. Also as for substrate geometry, we can formulate fine patterns to three-dimensional substrates up to its four surfaces, and the technology is highly evaluated. We also have been developing thick film technology in addition to technology developments to improve performance and durability of high reflecting coating.

Dealing with thin-films which mutate like living creatures

We struggle to evaluate and research thin-film thickness of nanometer order which is minute. In addition, depending on air temperature and humidity, the film mutates just like living creatures so we work on each of them while dealing with such unseen changes to meet customer's requests one by one. Since our thin-film technology is highly evaluated by customers, we would like to continuously develop it and know-how, aiming at achieving further high performance.
