Applying film deposition and thin-film processing technologies to the growing demand for submounts

　We have applied and developed our thin-film deposition and thin-film processing technologies cultivated through the manufacture of thin-film magnetic heads (HDD and FDD) and optical prism components to form thin-film electrodes, resistor films, solder films, etc. with high-precision fine circuit patterns that match the base materials of ceramic substrates and other substrates.
　We also offer patterning on three-dimensional surfaces and thick Cu plating.
　Our customers are not limited to Japan, but are using our products in Asia, Europe, the United States, and other parts of the world.
