Post-deadline submissions will be considered for the poster session, or oral session if space is available
Photomask Technology, formerly known as BACUS, stands as a distinguished forum where professionals and academics from the semiconductor industry and related organizations come together to present and discuss the latest advancements in photomask technology. The event covers a wide range of topics, including materials, design, fabrication, quality control, and wafer imaging characterization in EUV, DUV, and other related technology areas. The event is also situated alongside the EUV Lithography Symposium, and this co-location provides participants with a comprehensive scope and an opportunity to engage in productive discussions, exchange insights, and address challenges related to photomask and its crucial role in lithography.
With EUV lithography integrated into several generations of semiconductor products, the necessity for multiple patterning across more layers becomes inevitable. Given the significant costs associated with patterning, there is an imperative need for innovation in materials for EUV masks and pellicles, MDP (OPC, MPC, fracture) methods, writing techniques, metrology, and inspection capabilities to enhance resolution, yield, and productivity. Furthermore, the introduction of high-NA EUV scanners to the field necessitates the immediate securing of the entire infrastructure and refining of mask-making processes. Legacy technologies also require improvement to support existing applications and explore new opportunities in areas such as 5G, silicon photonics, IoT, MEMS, automotive, AR/VR, and others.
We extend a warm invitation to technologists, researchers, and students in the photomask and related fields to actively participate in our conference. This event serves as an excellent platform to exchange knowledge, insights, and ideas crucial for advancing the semiconductor industry. We encourage submissions covering a wide range of topics related to photomask research, development, manufacturing, and application. While we have a particular interest in the areas highlighted below, we welcome submissions from all related fields leveraging photomask technology. So, submit your abstract today and join us in shaping the future of our industry.
