Enhancing Technology for Next Generation Lithography
Organizer: Koji Asakawa (KIOXIA)
The performance of semiconductors has been boosted by on-going reduction of their fabrication sizes.   However, it is realized not only by reduction in lithographic resolution but also strongly by peripheral technologies such as multiple pattering, pattern transfer techniques and high etch durability materials.  This symposium focuses on the emerging materials and technologies that empowers the conventional methods to be finer, harder, and more precise for device fabrication.
