RF & Plasma Technologist

To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale—faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology.

The Semiconductor Products and Customers (Semi PC) business unit designs, builds and sells KLA’s product portfolio to help chip manufacturers meet high-quality standards for technologies like AI, data centers, automotive and electronic devices. Our inspection, metrology, and analytics systems detect and monitor defects across logic and memory chips, specialty semiconductors, wafers, reticles, advanced packaging, process equipment and materials. We also develop technologies for specialty processes, IC substrates, and PCB manufacturing, including etch and deposition, component inspection, and imaging and analytics.

The SPTS division provides advanced wafer processing solutions—including etch, deposition and vapor-based technologies—designed for R&D through high-volume production. With a global presence and strong customer support network, SPTS helps manufacturers across industries improve performance, yield and cost-efficiency. It also offers comprehensive service and spare parts through a worldwide network of service centers and qualified local agents.

In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.

Working as part of our Advanced Development group, this role is designed for an experienced technical expert who wants to remain hands-on while developing leadership capability.

The RF & Plasma Technologist will design and develop RF sub-assemblies and plasma hardware for advanced semiconductor etch and deposition systems. The successful candidate will work closely with process, electrical, mechanical, software and manufacturing teams to create robust subsystem solutions that deliver world-class plasma performance.

• Develop hardware associated with Etch & Deposition sources, electrodes, electrostatic chucks, gas distribution and chamber internals.
• Work with process engineers to relate hardware changes to plasma uniformity, ion energy, etch rate, selectivity and process repeatability.
• Apply vacuum, thermal, materials and contamination-control principles to subsystem design.

• Design, model, build and test RF matching networks, RF feed structures, transmission systems and grounding assemblies at proto-type level
• Investigate impedance matching, power-coupling efficiency, losses, harmonics and parasitic current paths.
• Characterise performance using network analysers, RF voltage-current probes, oscilloscopes and other RF diagnostic tools.
• Generate specifications, drawings, test methods and development reports.

• Plan and conduct laboratory experiments, analyse data and document conclusions.
• Support troubleshooting, failure analysis and structured root-cause investigations.
• Support prototype build, system integration, qualification and release into product development.
• Coordinate design reviews, risk reduction and structured root-cause investigations for projects in Advanced Development

• Support strategic customer engagements and communicate technical findings to internal and external stakeholders.
• Contribute to platform and subsystem technology roadmaps.
• Identify invention opportunities and support intellectual-property development.

• Work closely with…
