Halogen lamp for RTP system

Out on the fab floor, a 0.2°C drift across the wafer during photoresist bake can quietly eat your overlay margin and yield. In RTP, that lamp isn’t just a heat source—it’s the last word on thermal uniformity and repeatability. We build halogen lamps for RTP systems with tight spectral control and fast response. The filament geometry, quartz envelope, and reflector path are all tuned to give you a stable hot zone where wafer-level uniformity holds ±0.1°C. Output stays steady over thousands of cycles, so your critical thermal budget doesn’t drift from lot to lot. The assembly is cleanroom-compatible, using low-outgassing materials and particle-controlled construction to keep counts down where lithography simply won’t tolerate contamination. In lithography, the soft bake and hard bake steps need precise temperature profiles to lock in critical dimension and sidewall angle. Our lamps settle the hot zone fast, shorten ramp time, and cut thermal overshoot. The payoff is consistent photoresist behavior lot after lot, fewer reworks, and CD control you can count on. Energy use drops because the lamp heats on demand with minimal standby loss, and it’s engineered for 24/7 operation—less unplanned downtime. Here’s the reality with halogen lamps: they respond quickly, but you need stable power delivery and proper cooling to hold that ±0.1°C target. Match the lamp to the chamber geometry, and double-check electrical compatibility with your RTP controller. Filament life is finite, so plan preventive replacement intervals that line up with your process volume. Treat the lamp like a calibrated component, not a throwaway consumable, and your thermal process stays in control.
