Senior Optical Design Engineer

KLA is a global leader in diversified electronics for the semiconductor manufacturing ecosystem. Virtually every electronic device in the world is produced using our technologies. No laptop, smartphone, wearable device, voice-controlled gadget, flexible screen, VR device or smart car would have made it into your hands without us. KLA invents systems and solutions for the manufacturing of wafers and reticles, integrated circuits, packaging, printed circuit boards and flat panel displays. The innovative ideas and devices that are advancing humanity all begin with inspiration, research and development. KLA focuses more than average on innovation and we invest 15% of sales back into R&D. Our expert teams of physicists, engineers, data scientists and problem-solvers work together with the world's leading technology providers to accelerate the delivery of tomorrow's electronic devices. Life here is exciting and our teams thrive on tackling really hard problems. There is never a dull moment with us.

With 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 Surfscan group includes a team of engineers, technology development, apps engineers and product marketing focused on technology that enables wafer, IC and equipment manufacturers to develop, qualify and monitor their process tools. Defects and process non-uniformities detected on Surfscan equipment allow for early identification of yield excursions. The flagship Surfscan products include the SPx platforms for wafer surface quality and wafer defect inspection tools and systems for inspection of polished wafers, epi wafers and engineered substrates during the wafer fabrication process.

Job Description/Preferred Qualifications

Responsibilities:

• Facilitate the optical specifications, lens design, and supplier integration of new optics enabled products for the Optics Development Engineering group.

• Effective use of Code V or Zemax to design low residual aberration generating imaging lenses, relays, spatial/polarization beamsplitters and zoom lenses both from nominal design process to final Monte Carlo tolerance analysis and error budgeting.

• Construct complex system models using above components having all imaging paths with critical parameters needed to produce accurate and efficient raytracing simulations of Strehl/WFE performance, coherent and incoherent PSF size/shape, focal depth of field and pupil, multiple bounce ghost and non-sequential stray light analysis, and polarization ray tracing to quantify transmission, retardance, diattenuation.

• Interferometry experience preferred.
