We will accelerate EUV blanks development using the infrastructure for 6 inch plates. At present, cutting-edge semiconductors are limited to use in smartphones, artificial intelligence, and data storage as companies at the forefront of development can cover demand in those areas. Add to this the fact that there can be no foreign particles 23nm or more. •We have continuing business especially for optical blanks for several decades. So unlike traditional masks which are essentially blank slates until we pattern them, we need fiducials on the blank so that we can record where the defects are and, subsequently, decide precisely where on the blank to print the pattern to best avoid them.

We conduct weekly meetings with these manufacturers, and our employees around the world remain active in the industry. •HOYA is the only blanks supplier that covers optical (ArF, KrF), EUV, and LCD. •Most of the challenges in EUV mask blanks are in defects. In order to improve the circuit density of semiconductors, the development of extreme ultraviolet (EUV) lithography is in progress. Save your virtual seat today.EUV mask blanks consist of a layer of low thermal expansion material, because the mask absorbs about 30% of the EUV light and so gets hot and must not distort. However, innovation in EUV lithography over the past few years has indeed been remarkable, and, as we believe the period up to 2019 represents a peak period of technological innovation throughout the industry, our focus is fixed upon which direction of development is best for the Company.The strength of our mask blanks business can be traced to three sources: the ability to handle the full lineup of mask blanks, from standard mask blanks to advanced mask blanks, including those compatible with EUV lithography technology, stable product quality in our mass-produced items, and the ability to develop cutting-edge products. Business Overview. When EUV lithography technology is used in the manufacture of semiconductors for other purposes, we believe demand for our products will likely increase, as other semiconductor firms begin making semiconductors using EUV lithography technologies.Given its long history in the manufacture of optical glass, HOYA has proven adept in not only basic technologies such as polishing, cleaning, and flattening, but also other technologies, including those related to the sputtering deposition of film up to dozens of layers deep.

EUV mask blanks have been experimentally produced by EUV Limited Liability Co. (Livermore, Calif.). A mask blank serves as the substrate for a photomask. The next speaker was Franklin Kalk who is CTO of Toppan Photomasks. In the mask blanks for semiconductors business, contributions to expansion in profitability are expected from the development of next-generation EUV (Extreme Ultra Violet) technology, which will enable manufacturing of even finer circuit patterns. Mask Blanks for Semiconductors. We believe our strength lies in our ability to handle the entire scope of our customers’ needs, something no other company can match.Amid such an environment, we aim to expand profits and reduce manufacturing costs on all products, including high-precision products, and expand our market share through the reinvestment of earnings in the research and development of advanced and high-precision products.Our products do not merely meet given product quality standards, but are designed to fall within the middle of the product quality range standards, and our customers appear very pleased with the stable level of quality in our products.
