Advanced logic processes drive increased demand for wafer cleaning cycles
Wednesday, February 25, 2026 at 06:35 AM
Advanced semiconductor manufacturing processes are requiring a significantly higher number of cleaning steps, benefiting suppliers of wafer cleaning equipment.
Context
Screen Holdings is seeing a significant valuation boost as the global semiconductor industry transitions to 2nm and Gate-All-Around (GAA) transistor architectures. These advanced logic processes require a dramatic increase in wafer cleaning cycles to prevent "killer defects" at the atomic scale. As feature sizes shrink and 3D structures become more complex, the number of critical cleaning steps has climbed to over 200 per wafer. This shift has made high-precision cleaning equipment indispensable for maintaining yields in high-volume AI chip fabrication.
The market for wafer cleaning systems is projected to reach $6.91 billion in 2026, sustained by a compound annual growth rate of roughly 7.5%. Screen Holdings maintains a dominant competitive position, controlling approximately 27.6% of the batch cleaning market and sharing over 40% of the multi-chamber single-wafer segment with its primary rival. With major foundries ramping up 2nm production throughout 2026, the company is uniquely positioned to benefit from the growing "clean-etch-clean" loops required for the next generation of AI and high-performance computing hardware.
