|---|---|
| Optical or viewing requirement | Inspection windows require band, wavefront and coating control; opaque process quartz may prioritize purity. |
| Temperature and thermal cycling | Specify bake/process temperature, ramps, thermal cycling and CTE interface. |
| Chemical and cleaning exposure | Plasma, acids/bases, process gases, ionic contamination and cleaning sequence are critical. |
| Mechanical and mounting load | Vacuum/pressure differential, handling automation and clamp/contact points require fracture control. |
| Pressure or vacuum boundary | Semiconductor Equipment Glass: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Use semiconductor-compatible high-purity cleaning; control particles, ions, organics, water marks and non-contact clean packaging. |
