Disco Corporation President Kazuma Sekiya stated that the company holds over a 90% market share in advanced back-end semiconductor manufacturing equipment used for AI applications.
Context
Japanese semiconductor equipment giant Disco has confirmed it maintains a dominant market share of over 90 percent in specialized back-end tools required for high-end AI chips. CEO Kazuma Sekie highlighted that the company’s precision grinding and dicing machines are now essential for producing High Bandwidth Memory (HBM), the high-performance storage used in Nvidia GPUs and other AI accelerators. This near-monopoly positions Disco as a critical bottleneck and primary beneficiary of the global generative AI infrastructure build-out.
The company's dominance stems from the technical difficulty of 3D packaging, where memory layers must be thinned and cut with extreme precision to allow for vertical stacking. As AI hardware evolves toward more complex architectures, the demand for Disco’s proprietary thermal and mechanical processing technology continues to outpace the broader chip market. For investors, this high barrier to entry and overwhelming market lead provide Disco with significant pricing power and a direct link to the capital expenditure cycles of major global foundries and memory manufacturers.
