ACM Research: the history behind semiconductor wet-processing equipment

ACM Research was founded in California in 1998 to develop capital equipment for the semiconductor industry.

How ACM Research developed

Its early work included stress-free copper polishing and advanced wet-processing technology. The company established major operations in Shanghai during the 2000s and built a portfolio around wafer cleaning, plating and other process steps while retaining a US-listed parent.

ACM Research in 2026

By 2026, ACM Research supplied wet-processing and cleaning equipment used in advanced semiconductor manufacturing, with much of its development and production conducted through its China operations.

ACM’s growth reflects both the technical complexity of chip fabrication and China’s effort to develop more domestic semiconductor-equipment capability.
