As a pinoneer of photomask blanks that play important roles in semiconductor production, ULCOAT have been progressing along with the technological innovation of semiconductor integrated circuits.

The significant development of electoronics has largely contributed to the market expansion of office automation equipment and consumer electronics digital products. However, further development of digital-multimedia appears to be essential for the information scociety to support next generation. And that's the area which vacuum technology is applied the most.

ULCOAT always provide products that meet the needs of users and society by creating the new value for future happiness.

For various issues, we will continue to fulfill its social responsibility as a company.

President's Message

We lead the world in photomask blanks and flat panel display materials

CEO, Takeshi Haginouchi

ULCOAT have developed as a leading company in the material processing industry, as a member of ULVAC group which comprehensive vacuum manufacturers, provide customers with better solutions.

ULCOAT have developed the photomask blanks for semiconductors and the BM boards for high-quality colored filters, these have supported the rapid growth of semiconductors and LCD devices.

We will keep our focus on our customers and high-quality products, and will meet the demands of various fields such as semiconductor, display, MEMS, and Bio as a technology developer coping with cutting edge nanotechnology.

Business Strategy

We provide fascinating products using reliable vacuum deposition technology

The needs for nanotechnological products have increased all the more in semiconductor and display markets. ULCOAT will try to continue to achieve high quality that anticipates technological trend in markets, and produce attractive products, taking advantage of merits in oversea production such as quick response.

Glass MEMS (MEMS products with pattern formation on glass) have been challenging in response to the needs of new functional materials such as Bio-related DNA chip or micro cavity plate for a solder bump. With the foundation of non defective vacuum deposition technology and the developing nano technology, ULCOAT will respond to the various needs of high-tech material and processes, not only semiconductors and diaplay markets. In addition, we will respond to a lot of needs for nanotechnological products which have increased all the more in semiconductor and display markets.

Also we will strongly address maintenance and improvement of environmentally friendly production activities, and we will contribute to the society as responsible company in compliance with all laws.
