Summer 2027 - Process Simulation Engineering Intern - MS/PhD

The Office of the CTO is where innovation takes center stage. We inspire our global technical community to take on grand challenges, understand emerging trends, identify the critical inflections, and drive our sustainability, Environment, Social, and Governance (ESG) practices that will define the next generation of semiconductors and continued impact.

As a Process Simulation Engineer Intern, you’ll help build a virtual twin of plasma etch processes. You’ll develop physics-based models of how plasma etching works and fast machine-learning surrogate versions of those models, together connecting tool settings to predicted feature profiles. Your work will directly support data-driven process development for Lam’s etch products.

• Build and refine models of how plasma etches a surface: ion and neutral species interactions with the wafer, sticking and reaction probabilities, redeposition, and ion energy and angle effects.
• Calibrate model parameters against measured profiles (CD vs. depth from SEM/TEM images).
• Design simulation experiments (parameter sweeps, design of experiments) to generate training data.
• Build and validate fast surrogate models of the slower physics simulations, including checks on accuracy and uncertainty.
• Use surrogates to explore which settings matter most and to optimize process conditions.
• Write Python tools to automate simulation runs, data processing, and plotting.
• Document the workflow and present results at the end of the internship.

• Currently pursuing an MS or PhD in chemical engineering, physics, materials science, chemistry, or a related field.
• Strong Python skills, including hands-on experience building and training models in PyTorch (or a similar framework such as JAX or TensorFlow).
• Background in reaction kinetics, transport phenomena, or surface/plasma science.
• Hands-on experience building machine-learning or regression models.
• Strong analytical and communication skills, and the ability to work effectively in a team.
• Note this is an onsite-flex position (3+ day in the office).

• Coursework or research in plasma physics or plasma-surface interactions.
• Experience with surrogate modeling methods: Gaussian processes, neural networks, polynomial chaos, or reduced-order models.
• Experience with GPyTorch/BoTorch, physics-informed neural networks, or uncertainty quantification.
• Experience with design of experiments, sensitivity analysis, Bayesian calibration, or optimization.
• Experience with physics-based simulation tools (finite element, Monte Carlo, or feature-scale/profile simulators).
• Familiarity with semiconductor etch processes or SEM/TEM image analysis.

We believe it is important for every person to feel valued, included, and empowered to achieve their full potential. By bringing unique individuals and viewpoints together, we achieve extraordinary results.
