Trends in Japan’s semiconductor process pump market

Semiconductor process pumps are essential in the global market for exhausting corrosive gases and by-products during processes such as etching, deposition and ion implantation. As EUV lithography and 3D NAND become more widespread, demand is growing for highly reliable, corrosion-resistant pumps. Rising demand from the automotive and AI sectors, along with investment in new plants in Asia, is driving market growth, with the market expected to post annual growth of approximately 13.5% in the future.

Unlike the global market, Japan’s customer base is weighted toward IDMs rather than foundries and OSATs, with production focused on specific applications such as power semiconductors, sensors and analog devices. There is a strong tendency to prioritize energy efficiency and long-term reliability, as well as resistance to continuous operation on highly utilized production lines and long maintenance intervals. On the supply side, a conservative procurement approach that values business relationships with established domestic pump manufacturers remains firmly entrenched, creating high barriers to entry for emerging foreign companies. Technology adoption is cautious, with existing models gradually improved, validated and then introduced into production lines.

The applications attracting the most attention in Japan are etching and deposition, including CVD and PVD. Reliability is considered critical for high-performance pumps that can stably exhaust corrosive gases and by-products during these processes. Because the quality of etching and deposition directly affects yields, demand for pumps used in these applications is strong.

There are numerous pump manufacturers and related companies regarded as leading domestic players, but procurement and adoption practices in the Japanese market continue to place emphasis on long track records and reliability.
