Shift Left

We are focused on using the Shift Left approach, investing resources such as technology, personnel and expense into the early processes of product development. Through this approach, we are endeavoring to develop various technologies and conducting research for multiple future generations in order to realize the technology roadmaps we have created with customers.

In fiscal year 2022, we continued working on using less space for equipment, which is one thing our customers require. By optimizing the layout of equipment in cleanrooms, we enhanced the productivity per unit area of equipment, and also contributed to reducing environmental impact. Furthermore, through activities for E-COMPASS*, an initiative for building sustainable supply chains, we are also pursuing more efficient product development from an environmental perspective in partnership with our suppliers.

Through promoting the Shift Left approach we gain an understanding of customer needs at an earlier stage, and by reflecting the information obtained from feedback into our R&D and proposing superior products, we are contributing to maximizing yield for customer devices and capacity utilization of their mass production line equipment.

We are also promoting on-site collaboration for early delivery of evaluation equipment to customers’ fabs and development and research laboratories, and are working to accelerate the process in which R&D is reflected in mass production equipment as well as to optimize development efficiency.

Product Marketing

We are endeavoring to further enhance the productivity of product development by having our sales departments and product marketing departments appropriately fulfill their respective roles.
Our sales departments are responsible for ensuring that products and services are provided based on solid relationships of trust with customers.

Meanwhile, our product marketing departments work to plan and realize products that meet the future needs of customers in target markets, such as development planning to increase the value of products and services, and the examination of value-adding mechanisms. In conducting these initiatives, in addition to considering new products and functions based on the seeds of our development divisions, they also formulate plans for optimal collaboration including tie-ups with partner companies and consortiums.

Our sales departments and product marketing departments work together in developing product marketing activities that anticipate market needs and contribute to customers’ products, and in doing so, help improve our product competitiveness and promote our Shift Left approach.

Collaboration with Consortiums and Academia

We have focused on collaborative efforts with domestic and international consortiums and academic institutions (universities) to enhance our R&D capabilities and to create leading-edge technologies for a very long time.

Today, we continue our engagement in a wide range of areas from applications to product development. In the area of EUV and high-NA EUV*¹ lithography processes*², this is achieved through collaboration with imec located in Belgium. Furthermore, we participate in a global research hub for hardware development of next-generation AI in the U.S. state of New York, and have formed a partnership with BRIDG*³, which is a non-profit public-private partnership located in the U.S. state of Florida, as well. At our research center in TEL Technology Center, America*⁴, advanced R&D in the areas of front-end, back-end*⁵, and advanced packaging process areas are being carried out daily.

Additionally, we collaborate with the National Institute of Advanced Industrial Science and Technology (AIST), one of Japan's largest public research institutions. There we leverage AIST's world-class research environment and personnel to enhance our own development by conducting MRAM*⁶ and 2D material-related research. We do this to address the needs in the field of semiconductor technology development, which is becoming increasingly diverse.

From fiscal year 2022, we are also participating in iSyMs*⁷, an open consortium led by the Tokyo Institute of Technology and the University of Tokyo, to broaden the scope of our collaboration. We have also been working with SRC*⁸, a globally known U.S. consortium, and contributed to the production of the Decadal Plan for Semiconductors*⁹ published in October 2020.
