Biography

Dr. Kato currently serves as the Head of Research and Development for Synopsys’s mask data preparation (MDP) technologies—including industry‑leading products such as CATS and SmartMRC—where he leads global R&D teams and advances essential solutions for next‑generation photomask manufacturing.n

Abstract

When manufacturing semiconductor devices, electronic circuits are created on the wafer; however, the circuit layouts themselves are defined on the photomask, whose two‑dimensional patterns are optically transferred directly onto the device. Although these layouts are generated using EDA tools, the associated data processing steps are often perceived as complex and difficult to understand by engineers working in the mask industry.
This presentation aims to provide fundamental knowledge of semiconductor manufacturing data processing. It will explain the basics of data formats and processing flows, followed by an accessible overview of recent trends.
Furthermore, device scaling continues unabated, with technologies advancing beyond the N2 node and toward the emerging A14 node. The combination of multi‑beam mask writers and curvilinear data has become indispensable, and the P49 (Multigon) format defined by the SEMI standard is now being applied in production. This presentation will also offer a concise outlook on the latest manufacturing flows based on the new curvilinear data paradigm.
