Role summary

Lam Research is seeking an Engineering Technician 4 for their SEM Lab in Tualatin. The role involves processing samples using FEI/Thermo Fisher Helios SEM tools for top-down and cross-sectional imaging, including AutoTEM prepped lamella. Responsibilities include following lab methodologies for sample preparation, optimizing workflow for efficient throughput, communicating work estimates and feedback to management, and ensuring team alignment. The position requires 0-2 years of experience with a BS in physical science or equivalent training, and experience operating single beam SEM tools, particularly for XSEM imaging. Precision cleaving experience is a plus. The role offers a hybrid work model and a compressed back-end of week day shift schedule.

The group you’ll be a part of

The SEM Lab in Tualatin is committed to providing best-in-class microscopy services to support Lam’s engineering and development efforts. Through technical development and continuous improvement we solve difficult analysis problems and leverage efficiencies to increase our throughput and reduce our time to data.

The impact you’ll make

Your major responsibility will be to process samples using FEI/Thermo Fisher Helios SEM tools. Sample types will consist of top-down imaging, and cross-sectional SEM imaging. Additional responsibilities include imaging AutoTEM prepped lamella using installed STEM detector on SEM Tool.

What you’ll do

  • Follow lab methodology for TDSEM/XSEM sample preparation consistent with quality standards.
  • Optimize personal workflow for efficient throughput of samples.
  • Communication with lab management to provide work completion time estimates.
  • Provide feedback to lab management for continuous improvement opportunities in lab workflows.
  • Communicate with team members to ensure alignment on methodologies.
  • Protecting customer material and IP at all times.

Who we’re looking for

  • 0-2 years of experience with a BS degree in a physical science, or a specialized AS degree or equivalent professional training on materials science and analytical techniques. 
  • Experience operating single beam SEM tools, with particular focus in the preparation of cleaved cross-sections for XSEM imaging.
  • Sample prep experience in precision cleaving tools is a plus.
  • Ability to work a Compressed, Back-End of Week Day Shift Schedule. (Thu - Sat, rotating Wed)

Preferred qualifications

  • Knowledge of the physics involved with SEM tools, such as vacuum systems, voltage/current effects, and ways to work around charging issues.
  • Familiarity with key developments and materials in the semiconductor industry is a plus.
  • Experience creating and presenting technical documentation.
  • Experience in customer IP protection and sample handling is a plus.
