Job Description


  • Make architecture design of new generation electron optics system according to electron optics system performance requirement.
  • Simulate electron optical performance of new designed electron optics system, modify and finalize the architecture design, and define requirement of electronic modules which support the electron optics system.
  • Make mechanical design of new generation electron optics system based on the simulation result.
  • Assemble, and test the new-designed sub-modules, then integrate the sub-modules into an electron optics system, and perform basic performance testing in the test bench and write test reports;
  • Integrate new developed electron system onto the system platform; Verify and test the control functions of electronic and software controls modules.
  • Characterize the electron optical system?s resolution, current, distortion, and other optical characteristics on the system platform;
  • Make plans and lead electron optics performance experiments on the platform, analyze and interpret test data, develop solutions that optimize system performance. Diagnose complex subsystem problems across algorithms, software, electronics, mechanics, vacuum and electron optics.
  • According to the test result, provide input to new electron optics system specifications, system error budget, interfaces and working parameters for the optimum hardware/software solution.
  • Work with application engineers, according to the application practice and requirement from different wafers, provide the technical support to application engineer in the live demonstration and result analysis, and also provide significant input for the electron optics system improvement.
  • Occasional travel to vendors and customers might be required.



  • Master or Ph.D. degree in applied physics, or electrical engineering with a strong foundation in the fundamentals of physics and charged particle physics is required.
  • Experience with electron scanning microscopy, charged particle optics, high voltage, charged particle physics, vacuum systems and semiconductor fabs is desirable.
  • Strong diagnostic and trouble shooting skills in electron optics subsystems such as sources, optics and detectors.
  • The candidate must be hands-on and have good team working spirit.
  • The candidate must be self-driven and innovative.
