Key Responsibilities
Lead or play a major role in the architecture design, development, and verification of next-generation FIB systems or core subsystems (e.g., high-performance ion sources, low-aberration optical columns).
Solve critical technical challenges during product development and manufacturing, enhancing system performance, reliability, and yield.
Write detailed technical requirements, design documents, test plans, and patent applications.
Collaborate with technology suppliers and academic institutions to evaluate and introduce new technologies and components.
Provide top-level technical support to marketing, sales, and application teams, deeply understanding customer needs and feeding them back into product design.
Requirements(Core Technical Areas)
1.Ion Optics / Electron Optics Theory: Proficiency in the theory of charged particle beam generation, focusing, deflection, scanning, and aberration correction. Deep understanding of the sources and control methods for spatial resolution, beam current density, and aberrations (spherical, chromatic, etc.).
2.Ion Source Technology: Deep mastery of the principles, design, fabrication, lifetime, and key stability technologies of Liquid Metal Ion Sources (LMIS). Knowledge of other novel ion source technologies (e.g., plasma ion sources) is a plus.
Ultra-High Vacuum (UHV) Technology: Expertise in UHV system design, material selection, surface treatment, vacuum acquisition, and measurement techniques. Deep understanding of the impact of the vacuum environment on beam stability and sample contamination.
Precision Mechanics & Motion Control: Knowledge of design and simulation for ultra-precision motion stages (nanometer accuracy), vibration damping, stress control, and thermal management.
5.Detection & Signal Processing: Proficiency in the principles of detecting, amplifying, processing, and imaging signals such as secondary electrons, secondary ions, and backscattered electrons. Familiarity with integrating attachments like Energy Dispersive X-ray Spectrometers (EDS) and Electron Backscatter Diffraction (EBSD) systems.
