On a 300mm line, a 0.5°C drift in bake temperature will wreck CD control and push scrap higher. In a Class 1–100 cleanroom, one particle from the heater is all it takes to kill a die. We built our cleanroom infrared heater to eliminate both failure modes. What matters, technically We run short-wave infrared emitters for fast, direct energy transfer, and hold wafer-level uniformity at ±0.1°C across the bake zone. Temperature ramp and soak are repeatable run-to-run, so your soft bake and hard bake profiles stay locked. The heater body is cleanroom-friendly—smooth surfaces, low outgassing materials—and it produces zero particle emission while it runs. The control is tight enough to preserve thermal budget on advanced nodes, where margin is paper-thin. Why it fits the track In lithography tracks, you need heat that hits fast, holds steady, and doesn’t leave anything behind. Our infrared heater snaps to setpoint quickly, cutting cycle time without giving up profile control. It runs 7×24 with zero unplanned downtime, and the emitter life supports long campaigns without frequent swaps, so your line stays in state and maintenance stays predictable. The payoff is stable critical dimension, less scrap, and consistent yield. What you need to plan for The heater interfaces with standard track setups, but the thermal profile is sensitive to chamber geometry and airflow. Commissioning means mapping the hot zone and tuning the emitter layout to the specific bake chamber. Block out a short integration window, and verify particle count at operating temperature before you release the process.
