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 Broadband Plasma Division (BBP) provides market-leading patterned wafer optical inspection systems for leading-edge IC manufacturing. Logic, foundry, and memory customers depend on BBP products to detect yield-critical defects for process debug and excursion monitoring at advanced process nodes. BBP flagship products include the 29xx and 39xx series which leverage Broadband Plasma technology to capture a wide range of defects with ultimate sensitivity at the optical inspection speeds needed for inline defect monitoring. Job Description/Preferred Qualifications

We seek an expert in theoretical and computational electromagnetism to join the technology development team in the Broad Band Plasma division at KLA. This division develops the world’s most sophisticated optical inspection technology deployed by all semiconductor manufacturers to detect critical defects in wafers patterned with logic and memory devices.

An individual in this role will perform modeling and simulation to help understand, from first principles, the sensitivity challenges in optical detection of nanometer scale defects in semiconductor devices. The individual will contribute to building the future optical inspection technologies.

The individual in this role is expected to investigate research ideas through simulation and/or experiment, and to provide a solid theoretical basis for the results. The individual is expected to gain confidence of key stakeholders by demonstrating predictive value of models and simulations through collection and in-depth analysis of data.

The individual may initially spend significant time in performing simulations to optimize the geometry and composition of specialized device patterned wafers to increase sensitivity to critical defects. This work will be carried out in collaboration with major semiconductor device manufacturers.

We prefer candidates with at least 5 years of research experience in electromagnetism, and a proven track record to build and perform simulations in any sub-field of optics. Candidates should be skilled in scientific computing.

Education Requirements:

PhD in Physics, Electrical/Computer Engineering, or related fields.

Minimum Technical Skills:

Fourier optics for modeling of coherent and incoherent imaging systems, including the understanding of wavefront aberrations.

Deep familiarity with electromagnetic scattering theory and perturbation methods.

Ability to setup simulations of complex nanoscale circuitry of highly dispersive metals and dielectrics using finite difference time-domain and/or finite element frequency domain approaches.

Ability to verify results, perform convergence studies, and accurately choose numerical parameters for each simulation approach.

Design and execute experiments to test predictions of simulations and investigate novel detection approaches and algorithms on optical inspection platforms.

Knowledge of Python and C/C++ ecosystem for scientific computing.

Proficient with scripting workflows on Linux-based high performance computing clusters.

Additional Skills:

We will give strong preferences to candidates with proven track record in one or more of the following areas:

Image processing, signal processing and knowledge of linear systems.

Machine learning and classical techniques of modeling probability distributions in high-dimensional spaces.

Modeling of light-matter interaction in bulk solids and nanoparticles, including knowledge of time-dependent density functional theory and/or non-equilibrium Green’s functions.

Minimum Qualifications

PhD Degree + 3 years, or Master Degree + 6 years, or Bachelor Degree + 8 years

The company offers a total rewards package that is competitive and comprehensive including but not limited to the following: medical, dental, vision, life, and other voluntary benefits, 401(K) including company matching, employee stock purchase program (ESPP), student debt assistance, tuition reimbursement program, development and career growth opportunities and programs, financial planning benefits, wellness benefits including an employee assistance program (EAP), paid time off and paid company holidays, and family care and bonding leave.
