The growth rate of the semiconductor upstream material industry is lower than that of the semiconductor industry. Compared with semiconductor products such as DRAM and Flash Memory, it is one of the less volatile semiconductor sub-industries. Due to the need for advanced chemistry and materials technology, despite Japanâ€™s market share in the semiconductor market declining year after year, it continues to have a high market share in a number of semiconductor upstream materials.
