Sr. Electron Optical Systems Design Engineer

To make electronics you need chips wafers transistors reticles and... To make these you must see test and manufacture them at scalefaster and better than ever before. Thats where KLA comes in. Whether youre early in your career or an experienced professional youll 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 KLAs 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 e-Beam division plays a critical role in KLAs inspection ecosystem with tools that deliver high-resolution timely insights into defects and critical locations on the wafer. Used alongside KLAs patterned and bare wafer inspectors e-Beam systems help our customers quickly identify and understand yield-impacting issuesenabling faster more effective actions to correct the manufacturing process.
