About MKS
MKS makes precision instruments, integrated systems, components and process control technology that manufacturers rely on to keep production running smoothly. Its equipment is designed to sense, monitor, move, test, power and control key conditions on factory floors worldwide, and the company has built a name for itself in vacuum control, laser and photonics gear, and tools used in circuit board production.
The company organizes its work into three areas. One group focuses on vacuum and pressure handling, along with flow, valve and power delivery equipment used in processes like etching and deposition. Another group builds laser products, motion control hardware, optics and measurement instruments applied in photonics and wafer manufacturing. A third group makes laser-based tools for producing printed circuit boards, covering both flexible and rigid interconnects as well as testing equipment for ceramic capacitors. Customers come from semiconductor production, industrial fields, life sciences, research institutions and defense, and MKS reaches them through its own sales force, outside distributors and representatives, plus direct online ordering.
MKS traces its founding back to 1961 and runs its main offices out of Andover, Massachusetts. The stock trades on the NASDAQ under the ticker MKSI.
