Day-to-Day Responsibilities
Run wafer-processing tools, such as oxidation, photolithography and etching equipment, using the process recipe set by engineers.
Load and unload wafers and follow cleanroom entry, gowning and contamination-control rules at every step.
Monitor process readings and equipment logs, and report any deviation from specification to the shift engineer.
Support diffusion and doping steps, where wafers are heated in furnaces and dopant atoms are introduced to set the electrical properties of the silicon.
Carry out routine preventive maintenance and help diagnose faults on tools, escalating complex problems to maintenance engineers.
Record each lot and wafer run accurately so that the output can be traced and audited for quality.
Follow safety procedures for gases, chemicals and high-voltage equipment, and take part in structured shift handovers.
