Mechanical Engineer (Vacuum Chamber Design)

Job Description

1. Design the complete structure, sealing modules, thermal control system, and gas distribution system for Kiyo/Versys series etch vacuum chambers using Creo/NX UG , including 3D modeling, detailed drawings, and complete BOM preparation.
2. Perform multiphysics finite element analysis (FEA) using NX Nastran and COMSOL , including thermal stress analysis, vacuum structural strength analysis, internal gas flow simulation, and plasma thermal distribution to optimize temperature control and gas flow uniformity.
3. Select suitable chamber materials and metal sealing solutions for halogen plasma corrosion environments. Prepare vacuum chamber engineering specifications, assembly torque procedures, and manufacturing drawings in compliance with SEMI standards .
4. Lead prototype validation, including helium leak testing, ultimate vacuum performance testing, and thermal cycling reliability testing. Identify design issues such as vacuum leakage and temperature non-uniformity, and implement design improvements.
5. Coordinate with HQ R&D teams and local CNC precision machining suppliers in Penang to support prototype fabrication, Engineering Change Orders (ECO), and production issue resolution.
6. Collect long-term field failure data, prepare failure analysis reports, and continuously improve chamber structural designs to enhance product reliability and lifetime.
