ACM Research Receives Orders from Major US-based Global Semiconductor Manufacturer for SAPS Single-Wafer-Cleaning Tools

FREMONT, Calif., Dec. 01, 2021 (GLOBE NEWSWIRE) -- ACM Research, Inc. (ACM) (NASDAQ: ACMR), a leading supplier of wafer processing solutions for semiconductor and advanced wafer-level packaging (WLP) applications, today announced the receipt of two orders for ACM’s Ultra C SAPS V 12-chamber cleaning tools from a major U.S.-based global semiconductor manufacturer. Both tools are expected to be installed in the prospective customer’s U.S. facilities for use in its advanced processes. The first order, scheduled for delivery in the first quarter of 2022, is an evaluation tool to further confirm the tool’s cleaning performance and finalize specific features. The second order, scheduled for delivery in the second quarter of 2022, is a production tool intended for a high-volume manufacturing line.

“These orders mark a significant milestone in ACM’s globalization strategy and build upon recently- announced successes from three major semiconductor manufacturers with fabs in China. Today’s announcement demonstrates further success of ACM’s strategy to prove our proprietary and differentiated technologies with key customers in Asia and then expand to top-tier global players,” said Dr. David Wang, President and Chief Executive Officer of ACM. “This manufacturer chose ACM’s solution based in part on ACM’s ability to meet its advanced performance specifications. We believe the successful evaluation and deployment of these SAPS megasonic tools can lead to larger business opportunities with this prospective customer and other major customers in the region.”

ACM’s proprietary Space Alternated Phase Shift (SAPS) advanced wafer-cleaning technology employs alternating phases of megasonic waves in the gap between a megasonic transducer and the wafer. Unlike the stationary megasonic transducers used in previous generations of megasonic wafer-cleaning systems, SAPS technology moves or tilts the transducer while the wafer rotates, enabling megasonic energy to be delivered uniformly across all points on the wafer, even if the wafer is warped. SAPS is a faster process than conventional megasonic cleaning and does not experience material loss or create a rough wafer surface. SAPS achieves more thorough, comprehensive cleaning and has been demonstrated to 1xnm DRAM devices and beyond.

Forward Looking Statements
Statements in the first and second paragraphs of this press release with respect to the expected delivery of two Ultra C SAPS V 12-chamber cleaning tools, and the potential for additional sales of SAPS megasonic tools to the same customer in the future, are not historical facts and constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements, which are, in the case of the two identified tools, only expectations and, in the case of potential future sales, only projected goals, reflect management's current views and projections, are based on certain assumptions, and involve risks and uncertainties. ACM may not be able to deliver the two identified tools within its expected time frames for reasons outside of, or unknown to, ACM, and there can be no assurance that ACM will succeed in selling additional tools to the customer at any time in the future. Moreover, even if ACM succeeds in delivering the two identified tools on a timely basis, the tools will be subject to evaluation and acceptance by the customer and therefore there can be no assurance that the deployments will result in revenue to ACM. ACM undertakes no obligation to publicly update forward-looking statements to reflect events or circumstances that occur after the date hereof or to reflect any change in its expectations regarding these forward-looking statements or the occurrence of unanticipated events.
