On the lithography floor, you learn fast that a 0.5°C drift in bake temperature will move critical dimensions by nanometers—and that’s how a whole lot of wafers turn into scrap. Short-wave infrared heaters for micro wafer parts hit the problem where it lives, locking thermal behavior inside the process window.
What matters, technically
We build short-wave infrared emitters with a fast-response quartz envelope, tuned to semiconductor thermal budgets. Across the bake zone, wafer-level uniformity stays at ±0.1°C, so photoresist flow and solvent removal stay repeatable, lot after lot. The heaters run with low particle emission, fitting cleanroom Class 1–100. Output stays stable over 5,000+ hours, with minimal drift.
Why this works where it matters
Soft bake and hard bake set the photoresist profile that carries the mask image. With infrared heating, you get rapid, controlled ramps—shorter bake steps, no overshoot. The payoff is tighter CD control and less scum showing up in the etch steps. Energy use drops, too, because the emitters convert electrical input to heat efficiently and the thermal mass is low.
Here’s what you need to plan for
Installation comes down to matching the tool’s voltage, connector type, and aperture dimensions. You also have to align the emitter to the wafer path—otherwise you lose the uniformity you’re after. Infrared systems need a clean optical path; any shielding or window coating can change the spectrum and shift temperature. Plan on routine calibration to keep that ±0.1°C spec intact.
