VR SOP Training for Photomask Manufacturing

Precise, contamination-free steps from blank to inspected mask

Mask shops require immaculate handling and exact recipes. Spark creates bespoke VR training that mirrors your blank inspection/clean, resist coat/bake, pattern writing, develop/etch/strip, metrology and final clean/pack—so technicians practise the exact sequence safely.

Common pain points

• Cleanliness: defect prevention, particle control and storage discipline.
• Process control: resist thickness, exposure/dose, etch time and CD targets.
• Metrology: CD/overlay, defect maps and rework criteria.
• Handling: tools, carriers, ESD and shipping packs.

How our custom build helps

1. Capture SOPs & SPC: recipes, limits and alarm responses.
2. Create scenarios: coat/bake, write, develop/etch, inspection and clean/pack.
3. Coach in VR: clear prompts that match your MES and travellers.
4. Assess: right-first-time, excursion trends and retraining needs.

Benefits

• Lower defectivity and tighter CDs.
• Safer chemical and clean handling.
• Faster readiness for new hires and tool moves.

Why Spark

We mirror your mask flow and limits—so skills transfer straight to the shop.
