Process Engineer

Role: Process Engineer
Reporting to: Process Development Director
Location: Silicon Valley, CA

Design semiconductor processes to realize novel optoelectronic devices. Tasks include:

  • Fabricate components in a wafer fab, including process steps such as lithography, dielectric and metals deposition and semiconductor etching, implantations and anneals.
  • Design fabrication process flow including all process steps enumerated above.
  • Mask layout for various lithography tools such as contact aligners, steppers, or direct-write laser.
  • Manage technicians and operators in using semiconductor processing tools, such as e-beam evaporator, PECVD, sputtering, dry and wet etching .
  • Source and manage contractors and vendors to complete process steps
  • Characterize processes, including using profilometer, SEM, electrical and optical test.
  • Work with outside laboratories to characterize processes and devices.
  • Electrical and optical testing of components.
  • Failure analysis and modelling of optoelectronic devices throughout process.
  • Reliability testing, analysis, and troubleshooting.


  • Knowledge of lithography and mask design software (L-edit, Klayout, etc.).
  • Knowledge of with clean room environment and with semiconductor wafer fabrication processes (metallization, etching, dielectrics, thin film characterization, etc). 1 year or more experience preferred.
  • A B.S. degree or higher in electrical engineering, materials engineering, chemical engineering, physics, or equivalent (M.S. preferred).
  • Excellent interpersonal/communication skills and ability to overcome unforeseen challenges in a dynamic work environment with shifting timelines.
