On the fab floor, a half-degree drift during soft bake or hard bake is enough to wreck linewidth control and CD uniformity. The thermal budget doesn’t negotiate. When RTP lamps miss their mark, you don’t just pay for lamps — you pay in scrap and rework. We build RTP lamps — short-wave, medium-wave, and carbon-fiber-based — to hold wafer-level temperature uniformity within ±0.1°C across the process window. Quartz parts and sealed assemblies keep particle generation at zero, so you stay inside cleanroom Class 1–100. Output stays flat within 2% over 5,000+ hours, and the fast ramp rates keep high-throughput recipes moving without sacrificing repeatability. Precision terminations and matched impedance mean these drop straight into AMAT, Applied Materials, TEL, and similar RTP platforms. In lithography and photoresist processing, consistent soft bake and hard bake temperatures translate into fewer defects, tighter CD distributions, and a higher first-pass yield. You keep the process window in spec, cut down on metrology re-qual, and see fewer unplanned line stops. Energy efficiency comes from lower voltage operation and optimized spectral output — you reduce power draw while keeping thermal response where it needs to be, so operating cost comes down along with the replacement lamp price. Installation is straightforward, but thermal coupling and lamp positioning have to match the chamber geometry. After replacement, double-check emissivity settings and calibration offsets — even a high-precision lamp will underperform if the sensor feedback loop is off. Plan lamp swaps during PM windows to avoid recipe drift and keep uptime steady.
