On the fab floor, photoresist bake isn’t optional—it’s the spec. Push off by 1°C on soft bake or hard bake, and your CD control drifts. One particle excursion, and you can scrap the lot. We designed our chip-on-wafer infrared lamps to take that variability off the table, matching the thermal behavior that advanced semiconductor tools demand. What matters under the hood We use near-infrared (NIR) emission to dump energy straight into the wafer and photoresist. That gives you fast, localized heating with low thermal inertia. Across the process zone, you get wafer-level uniformity within ±0.1°C, and repeatability that keeps you inside tight thermal budgets. The system is built for cleanroom life—good to go in Class 1–100—and it’s set up so steady-state running doesn’t trigger particle excursions. In qualifying installations, it has run 24/7 with zero unplanned downtime, and it supports the kind of precise thermal control lithography and photoresist bake sequences need. Why this works in production In a real fab, heat has to arrive fast, hold steady, and leave nothing behind. NIR heating slashes bake ramp time without overshoot, so you cut cycle time and improve throughput. With tight uniformity, you reduce the risk of edge-bead issues and thickness non-uniformity—yield on patterned wafers improves. Energy use is lean because heating is on-demand and standby losses are small, so operating cost drops. The lamps also give you a validated, performance-equivalent option to international equipment standards, so you can swap them in without requalifying the whole line. What you need to get right Installation comes down to matching the tool’s mechanical and electrical interfaces. Confirm voltage, connector type, and mounting clearances before you swap. The lamp performs best when the optical path stays clean and the target distance doesn’t move—any drift shifts the intensity distribution. We include application notes for alignment and cleanroom handling so you can keep particle counts stable.
