Recently, semiconductors are developing around technologies that can store and process vast amounts of data. At its core are EUV lithography and packaging technology. However, data for understanding trends in semiconductor technology development are insufficient. Thus, in this study, patent analysis was conducted by subdividing EUV lithography and packaging technologies. As a result of patent analysis, EUV risography is mainly developing technology to produce pelicles and blank masks. Packaging technology is mainly developed in Fan-out technology, especially technology that realizes high density by increasing the number of chips, or reduces the actual field area by stacking vertically. These analysis data are expected to help establish future research directions.
