Japan’s hard CMP pad market is driven by demand from semiconductor manufacturing equipment and electronic component manufacturers, with use expanding particularly in the planarization process for 300mm wafers. The market is expected to grow as advanced technologies and high-volume production investment continue, while 200mm demand is expected to remain stable.
Japan’s hard CMP pad market is seeing expanding demand, mainly from semiconductor manufacturing equipment and electronic component manufacturers, with use increasing particularly in the planarization processes associated with advanced logic and 3D NAND stacking. Government subsidies and investment incentives are also supporting the market, while demand is rising for hard pads that enable high-precision polishing. In cost-sensitive fields, however, adoption remains cautious, limiting demand growth.
By application, the market primarily serves 300mm and 200mm wafers and is becoming bifurcated because the two segments are at different stages of growth. For 300mm wafers, miniaturization and the increasing number of 3D NAND layers are driving demand for greater uniformity and longer service life. The 200mm segment is a mature market with stable demand, but is more susceptible to the impact of alternative technologies.
Major companies include DuPont, CMC Materials and 3M, while domestic production maintenance and technological improvements are progressing. The market is expected to grow at approximately 11.30% over the next several years, with continued semiconductor miniaturization expected to be the main growth driver. However, factors including export-control risks, higher raw-material costs and the emergence of alternative technologies could affect supply.
