Out on the fab floor, the photoresist profile is nailed down during soft bake and hard bake. A half-degree drift across the wafer is enough to shift critical dimensions, throw overlay off, and wipe out hours of lithography work. The reflector in the curing lamp isn’t just a passive part — it shapes the thermal budget that keeps the process repeatable.
What matters under the hood
This reflector is built for wafer curing lamps in the semiconductor line. It holds wafer-level thermal uniformity within ±0.1°C, meets cleanroom classes 1–100, and is engineered for zero particle generation. The quartz reflector keeps output stable under 24/7 duty, with units running 5,000+ hours and dropping less than 5% in output. Run-to-run, shift-to-shift, you get the same temperature profile and the same photoresist response, every time.
Why it holds up in production
This reflector translates into solid photoresist processing. In the bake track, the setpoint lands across the whole wafer, which cuts edge bead and tightens CD control. The payoff is fewer rework lots, lower scrap, and cycle times you can plan around. Energy use comes down because heat stays focused on the wafer instead of bleeding onto the chamber walls. You get consistent soft bake and hard bake profiles, even when the line is running mixed products and tight lots.
What you need to get right
Installation hinges on exact lamp alignment to the reflector’s focal axis — misalignment of just a few milliradians can create hot spots and kill uniformity. The reflector works with standard halogen and short-wave lamp fixtures, but you still have to verify the tool-specific mounting brackets for each track model. After the swap, run a quick qualification: check temperature uniformity and particle count before you put the tool back into production.
