On the line, flexible electronics wafers don’t forgive thermal excursions. A soft bake that drifts even a little throws off critical dimensions in the next lithography steps. A hard bake that runs hotter than it should can crack thin-film layers or kick off stress migration. The fallout is scrap, rework, and yield loss that compounds across the lot. What matters under the hood We built the heater around short-wave infrared, so you get sub-millimeter thermal uniformity across the substrate. During photoresist bake, it holds wafer-level temperature control to ±0.1°C, and the repeatability stays inside the thermal budget of delicate polyimide and ultra-thin carrier stacks. Infrared energy drives straight into the photoresist, cutting thermal lag and letting you ramp fast without overshoot. The platform is cleanroom-ready for Class 1–100, with materials and surfaces chosen to keep particle counts down. And “zero particle generation” isn’t a tagline—we measure it against metrology thresholds inside the real process window. Here’s why it sticks in flexible electronics: you need heat in the resist, not bleeding into the tool. This heater locks down the bake profile for both soft bake and hard bake, so line-width control and adhesion stay consistent wafer to wafer. Tight uniformity cuts edge-bead anomalies and trims the need for extra trimming exposures. You use less energy because the infrared source heats only the target, not the chamber around it. Reliability comes from components rated for 24/7 cadence, with documented uptime in production where unplanned downtime translates straight to missed lots. A few practical notes. The heater plugs into standard semiconductor equipment interfaces, but it needs its own dedicated electrical circuit and clean dry air supply to keep infrared output and cooling stable. Plan a short commissioning window to dial the thermal profile to your resist stack and substrate thickness. Once calibrated, it holds setpoint with minimal drift—even when you swap carriers.
