Group/DivisionWith over 40 years of semiconductor process control experience, chipmakers around the globe rely on KLA to ensure that their fabs ramp next-generation devices to volume production quickly and cost-effectively. Enabling the movement towards advanced chip design, KLA's Global Products Group (GPG), which is responsible for creating all of KLA's metrology and inspection products, is looking for the best and the brightest research scientist, software engineers, application development engineers, and senior product technology process engineers. The RAPID division is the world leading provider of reticle inspection solutions for the semiconductor industry. The company provides inspection solutions to both the mask shops and the semiconductor fabs to ensure that lithography yields are consistently high thus enabling cost-effective manufacturing.
Job Description/Preferred QualificationsKLA is launching its most advanced reticle inspection tool, built on a multi zone, ultra clean vacuum (UCV) architecture. As a Senior Vacuum Architect, you will own the end to end vacuum operation scheme-from architecture and contamination control strategy to pump down/vent/transfer sequencing, interlocks, and factory acceptance criteria. You will lead cross functional design reviews, translate platform requirements into subsystem specifications, and ensure the vacuum system enables world class optical performance, reliability, and high volume manufacturability. Aligned to the internal Vacuum System Design Review process and architecture-level responsibilities for a designated Vacuum System Architect.
Qualifications- Education: MS/PhD in Mechanical Engineering, Applied Physics, Materials Science, EE, or related discipline.
- Experience: 8-12+ years designing and operating UHV/UCV systems in complex, multi-chamber tools (semiconductor or equivalent precision instrumentation). Demonstrated ownership of vacuum operation schemes and PLC-controlled interlocks for high-reliability platforms. (Practice areas reflected in KLA's vacuum architecture materials.
- Technical depth: Pumping/conductance modeling, contamination control (hydrocarbon, particles), hydrogen/ozone processes, getters/TMP selection, vacuum gauging, GCMS methods, materials/finishes for UCV, and vibration/isolation fundamentals.
- Tools: Proficiency in system modeling (e.g., COMSOL/ANSYS or equivalent), scripting for analysis (Python/Matlab), PLC/HMI collaboration, and CAD/PLM workflows.
- Soft skills: Cross-functional leadership, clear technical writing, supplier engagement, and mentoring.
Nice-to-Have- Experience with EUV-compatible materials, reticle handling/transfer, and optical contamination control.
- Background in precision metrology systems and multi-column imaging platforms.
