Semiconductor Equipment Contract Manufacturing
Keller Technology Corporation (KTC) is a trusted partner in contract manufacturing for semiconductor OEMs. With deep experience building high-complexity machinery, cleanroom-compatible systems and vacuum-integrated assemblies, we provide the precision, repeatability and supply chain reliability demanded by the world’s most advanced fab tool manufacturers. Our vertically integrated capabilities support build-to-print and semi-custom production of high-level assemblies (HLAs) and turnkey equipment for front-end and back-end semiconductor process equipment.
Specialized Capabilities for Semiconductor OEM Manufacturing
Semiconductor equipment manufacturing requires a unique blend of advanced precision, contamination control and system integration. Keller supports your needs with:
Precision Fabrication and Machining
Keller delivers precision fabrication and machining for complex weldments, machined structures and vacuum chambers. Our capabilities include 5-axis machining of large-envelope components and tight-tolerance fitment across multiple mating surfaces to support high-accuracy assemblies.
Cleanroom-Compatible Assembly
We support cleanroom-compatible assembly through ISO Class 7 and 8 assembly areas designed for contamination-sensitive builds. Our team produces subassemblies and HLAs intended for cleanroom tool integration, with contamination-controlled packaging and delivery.
Vacuum System Integration
Keller provides full vacuum system integration, including welding and fabrication of vacuum enclosures and subcomponents. We support helium leak testing and RGA, along with cleaning and bake-out processes, and integration of turbo pumps, gauges, valves and vacuum plumbing.
Electro-Mechanical & Fluid Integration
Our team supports electro-mechanical and fluid integration for complex HLAs, including routing and termination of cable assemblies. We install pneumatics, fluid handling and gas distribution systems, and complete final test and debug of power, control and motion systems.
