KLA Careers

Photophysics Research Engineer

Company Overview

Calling the adventurers ready to join a company that's pushing the limits of nanotechnology to keep the digital revolution rolling. At KLA, we're making technology advancements that are bigger—and tinier—than the world has ever seen.

Who are we?  We research, develop, and manufacture the world's most advanced inspection and measurement equipment for the semiconductor and nanoelectronics industries. We enable the digital age by pushing the boundaries of technology, creating tools capable of finding defects smaller than a wavelength of visible light. We create smarter processes so that technology leaders can manufacture high-performance chips—the kind in that phone in your pocket, the tablet on your desk and nearly every electronic device you own—faster and better. We're passionate about creating solutions that drive progress and help people do what wouldn't be possible without us.  The future is calling. Will you answer?


The Office of the Chief Technology Officer (CTO) plays a critical role in developing advanced long-range technology in collaboration with product divisions and strategic marketing, working on future technology like light sources, lasers, and sensors. We are engaged in the research and development process, and once the technology is mature, we partner with product engineering groups who then build products based on the technology we’ve developed.

The Office of the CTO also provides technical input into KLA’s strategic planning process, program reviews and Product Life Cycle (PLC) phases. We provide our broad technology expertise and cross-division experience to ensure we leverage the collective knowledge within our company.



This position requires a solid understanding of interaction mechanism between photons and materials, and its application to photochemistry, photocontamination, and materials selection under high power ultraviolet light exposure. The candidate must have high proficiency in experimental and data analysis, demonstrate the ability to extract clear results from complex data sets.

The candidate will provide guidance and leadership in the following areas:

  • Surface analytical and data analysis; Extraction of clear results and conclusions from data sets.
  • Making actionable plans from analysed data and discussions with subject matter experts.
  • Failure analysis while working closely with other engineering groups, such as material research scientists, optics engineers, opto-mechanical engineers and laser systems engineers to ensure the feasibilities of new material/process to KT products
  • Strong team building with CTO team in Milpitas and other groups involved in the projects.
  • Understands UV driven photo contamination, and implementation of control via materials selection, cleaning processes and purge control. Establish the reliability model of optics under certain UV radiation conditions.
  • Provides guidance to opto-mechanical engineers to meet reliability and performance specs of our next generation opto-mechanical sub-systems.
  • Guiding the design teams on proper contamination control packaging/materials selection
  • Conducting laser damage test and analysis as needed
    • Optical coating improvements
