Full job description
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.
Group/Division 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 Broadband Plasma (BBP) division is the market-leading optical inspection system used by logic, foundry, and memory customers to detect critical defects at advanced nodes. These tools combine broadband plasma technology with unmatched sensitivity and speed to support high-volume manufacturing.
What You'll Do In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.
-
Design, prototype, and build the next generation of broadband plasma (BBP) wafer inspection opt-mechanical assemblies.
