About ACM Research
We supply advanced, innovative capital equipment developed for the global semiconductor industry.
Our products are designed to address yield-critical and performance-sensitive process steps that become increasingly difficult as semiconductor devices scale to smaller geometries and more complex structures. We focus on developing differentiated process solutions that enable effective particle removal, uniform material deposition, and reliable process control, while helping customers manage cost of ownership, throughput, and environmental considerations. We believe this approach has supported broader adoption of our tools across multiple technology nodes and device types.
