On the fab floor, a 1°C drift in the soft bake can wipe out an entire wafer lot. We built custom infrared heaters to take that risk off the table. They give you repeatable, wafer-level thermal control across wafer drying, photoresist baking, package curing, and post-clean drying. What matters under the hood The core is near-infrared with a tailored spectral profile, heating the target directly—no bath, no contamination. Wafer-plane uniformity holds at ±0.1°C, and shot-to-shot repeatability stays within ±0.5°C. Response is under two seconds, so the loop can stay tight. Cleanroom Class 1–100 is achieved with a quartz/ceramic assembly, zero-outgassing materials, and a particle-shed design that keeps counts down. These units are built for 24/7 operation, with MTBF in the tens of thousands of hours and swap-in modules to cut unplanned downtime. In lithography, soft bake and hard bake set the tone for critical dimension control. Our heaters lock in the photoresist thermal budget, which drops line-width variation and lifts yield. For wafer drying and post-clean drying, fast, uniform heating keeps streaks and watermarks off the surface—without contact. In packaging, the same platform delivers consistent curing profiles for encapsulants and underfills, shortening cycle time while holding adhesion and reliability. Energy use drops, too, because the heat goes straight into the process, not into a big chamber mass. Here is the thing: these heaters are tailored to your tool. Chamber geometry, clamp style, and sensor placement all matter. Commissioning is quick, and you’ll need clean, dry carrier air to keep the window clear and setpoints stable. Matching the spectral output to your substrate stack is essential; we provide the application data to tune emissivity and reflectivity for each process.
