Business Units & Products

MKS Instruments enables technologies that transform our world. We deliver foundational technology solutions to leading edge semiconductor manufacturing, advanced electronics and specialty industrial applications. We apply our broad science and engineering capabilities to create instruments, subsystems, systems, process control solutions and specialty chemicals technology that improve process performance, optimize productivity and enable unique innovations for many of the world’s leading technology and industrial companies. Our solutions are critical to addressing the challenges of miniaturization and complexity in advanced device manufacturing by enabling increased power, speed and feature enhancement for optimized connectivity. Our solutions are also critical to addressing ever-increasing performance requirements across a wide array of specialty industrial applications. We are organized in three divisions: Vacuum Solutions, Photonics Solutions and Materials Solutions.

Vacuum Solutions Division

MKS provides advanced automation solutions including controllers and I/O devices, software and analytics for Industry 4.0 and smart factory automation, and custom control systems. The MKS automation portfolio enables advanced process control by providing EtherCAT® connectivity, programmable safety, multizone temperature control, edge analytics, and IoT/cloud connectivity.

MKS provides gas flow and delivery products including mass flow controllers and in-situ mass flow verifiers to precisely measure and control gas flow. Upstream pressure controllers with integrated mass flow meters provide pressure measurement and control while monitoring mass flow rates for critical process applications. MKS flow ratio controllers accurately and repeatedly divide gas flows into precise flow streams. EtherCAT is available on select products.

MKS provides gas analysis solutions for real-time vacuum quality control, contamination detection, process monitoring, and compositional analysis. Products offered include residual gas analyzers (RGAs), process RGA systems, atmospheric pressure mass spectrometers, and optical gas analyzers. MKS also offers flexible and scalable software platforms to leverage sensor data and enable powerful process optimization and monitoring capabilities for advanced manufacturing environments.

MKS provides plasma systems that deliver fluorine, oxygen and hydrogen radicals. We manufacture ozone generators that produce ultra-pure, high concentration ozone gas and dissolved gas delivery systems supplying ozonated water, dissolved CO2 and dissolved NH3. In addition, Microwave Plasma Delivery Subsystems are available in 1.8 or 3 kW and provide safe delivery of atomic species to the wafer. EtherCAT is available on select products.

MKS provides high reliability RF power and microwave generators. Our RF generators deliver solid state power from low to very high frequencies (VHF) and combined with our Impedance Matching Network and V/I probe provide a complete RF delivery system. Our industrial microwave generators and systems generate power levels from 1 to 75kW and are adaptable to a wide range of applications.

MKS Baratron® capacitance manometers provide highly accurate and repeatable direct pressure measurement and are insensitive to gas composition. In addition, MKS has a wide range of indirect pressure sensors, transducers and modules that use hot and cold cathode, Piezo and Pirani gauge technologies. These products measure pressure in corrosive and noncorrosive environments over 14 decades of range from above atmospheric to ultra-high vacuum. EtherCAT is available on select products.

MKS provides a variety of vacuum valves including butterfly valves for pressure control, isolation valves and gate valves. Heated and unheated configurations are available as well as specialty valves for high cycle count and highly corrosive environments. In addition, MKS provides integrated vacuum solutions including complete turn-key solutions for foreline plasma clean, effluent management with heater jackets and controllers, process traps, virtual walls, and integrated vacuum measurement and control assemblies. EtherCAT is available on select products.

Photonics Solutions Division

MKS provides a wide range of high precision motion control products including linear and rotation stages, hexapods, controllers, piezos and industrial OEM sub-assemblies. Our vibration isolation solutions, specialized light sources, laser power measurement and beam characterization instruments, optical to electrical converters, solar simulators and laser diode control are used in photonics applications. Products used to mount, position, or support optical components and systems are also part of the MKS offering.

MKS develops and manufactures advanced pulsed and continuous wave diode-pumped solid-state, fiber and hybrid fiber lasers for precision applications. Pulse widths span nanosecond, picosecond, and femtosecond, and wavelengths range from infrared and visible to the ultraviolet.

MKS provides precision optical components and complex lens assemblies across the infrared, visible and ultraviolet spectrum. In addition to custom subsystem solutions, products include optical filters, thin film coatings, high performance gratings, replicated mirrors, windows, spherical, aspherical and cylindrical lenses, laser optics, refractive, reflective, catadioptric optical assemblies on a build-to-print or build-to-spec basis, and off-the-shelf high-performance IR thermal imaging lenses and continuous zoom lenses.

MKS provides fiber-optic sensing solutions for high-precision measurement of temperature and position in extreme environments with high RF power, high temperature, vacuum, plasma and reactive gases.

MKS provides laser-based micro manufacturing and component test systems including high-speed laser processing of flexible PCBs and flex interconnects, microvia drilling systems for high-speed HDI laser processing, IC packaging and substrate processing. Our ESB solutions also include a line of high-volume, multi-layer ceramic capacitor (MLCC) test systems with technology expertise to deliver high-speed testing of over 1 million chips per hour.

Materials Solutions Division

MKS provides coating chemicals and equipment for the production of printed circuit boards, package substrates, semiconductors, lead frames and connectors. We offer leading horizontal plants and wet chemical process technologies in the areas of surface treatment, metallization, electrolytic coating and finishing, as well as pad metallization, copper coating, RDL, TSV and dual damascene coating.

MKS provides leading functional and decorative surface finishing solutions—from pretreatment to final sealing. Our comprehensive systems-and-solutions approach combines chemistry, equipment, and service in a wide variety of applications including automotive, smartphones, next-generation connectivity and cloud computing, big data processing infrastructure, medical equipment, household appliances and more.
