On the lithography floor, photoresist bake isn’t just a thermal step—it’s a dimensional one. A 1°C drift in soft bake will show up in critical dimension control and sidewall profile. We built our infrared lamp for photoresist around that reality, aiming for wafer-level thermal uniformity of ±0.1°C and bake profiles that repeat across the entire lot. What matters, technically We run short-wave infrared with a fast-response emitter to deliver heat that’s fast and clean. The system holds setpoint tightly during both soft bake and hard bake, with closed-loop control that compensates for lamp aging and line voltage swings. The build is compatible with Class 1–100 cleanrooms, using materials and seals that keep particle generation down. In production, that means fewer defects, stable yield, and photoresist performance that stays consistent from the first wafer to the last. Why this works on the floor Wafer drying, photoresist pre-bake, and post-exposure bake all have the same requirement: control the thermal budget without adding contamination. Our infrared approach heats only the target, so you don’t load up the surrounding hardware, and you cut energy use. The payoff is shorter cycle times, a stable process window, and predictable line-of-sight heating that keeps up with advanced nodes. You get repeatability you can document for audit, and uptime you can actually plan around. A few practical notes Infrared bake performance comes down to matching lamp spectrum and power density to the resist stack and wafer size. Expect a short commissioning window to tune emissivity, scan speed, and temperature profile for each recipe. Also, the lamp has to integrate with your existing controller or SECS/GEM interface—plan on one afternoon for electrical and communication alignment so you don’t see drift after startup.
